Repair your computer in Windows 8 and 8.1By Margus Saluste, www.winhelp.us. Last modified: 2015-02-13.

If Automatic Repair fails and you cannot even get into Safe Mode, then most probably there are some errors or missing files on your hard disk that prevent

Windows 8 or 8.1 from starting correctly. Bootable installation media (DVD or USB) or Recovery Drive/System Repair Disc are helpful in such cases.

Those who have Windows 8 or 8.1 installed on SSD, beware: turn off built-in Disk Defragmenter; there is a known bug in it that starts defragmenting (not

using the TRIM command) SSD-s. This will lead to decreased lifetime and failure of the drive.

This is a two-page article - page 2 covers Refresh your PC, Reset your PC and restoring a system image.

Common problems with Windows 8 and 8.1 installations

Here is a list of problems that users encounter most often:

Endless Automatic Repair failures and restart loops - you cannot disable Automatic Repair, but you can boot from installation media or Recovery

Drive to fix errors and make Windows 8 or 8.1 usable again.

The behavior can also be an indicator that Windows 8/8.1 does not have required drivers for a disk controller. You can then enter BIOS/UEFI and set your

disk controller mode (aka SATA mode, RAID mode) to Standard (aka Standard IDE or SATA, Legacy) instead of AHCI or RAID (take note of the original

setting first!). This will often ensure that Windows knows which drivers to use for booting from the system drive.

In case you have multiple hard drives, power off your computer and remove its power cord. Then disconnect drive cables from all hard disks other than the

one where Windows is installed. Plug the power cord back in and see if this helps Windows to boot properly.

After Windows 8/8.1 starts, upgrade storage drivers and software using Intel's Driver Update Utility or find the driver software from AMD's site. This often

solves all problems.

If nothing helps, boot into Recovery Environment from Recovery Drive/System Repair Disc or Windows 8/8.1 installation media, open Command Prompt

and follow these instructions to disable Automatic Repair completely.

Disk check runs each time Windows 8/8.1 starts - on multi-boot systems (Windows 8 or 8.1 is installed along with an older version of Windows or

some other operating system) you need to disable the Fast Start-up feature in Shutdown settings. The feature (previously known as Hybrid Boot) enables

significantly shorter load times while Windows 8/8.1 starts after a shutdown or sleep/hibernation, but the file that contains fast boot information can be

damaged by starting another version of Windows or another OS (Linux, for example). This causes Windows to run a disk check each time.

To resolve the issue, open Control Panel in Windows 8 or 8.1. Type "power" into search box and click Change what the power buttons do.

In the Define power buttons and turn on password protection window, click Change settings that are currently unavailable.

Then, in the Shutdown settings section, clear the Turn on fast start-up (recommended) check box and click the Save changes button.

Windows 8 or 8.1 is unable to boot from a GPT drive on UEFI-enabled devices - if you formatted or converted your system drive from MBR

partitioning to GPT, you must ensure the EFI boot options state "UEFI only". Windows 8 and 8.1 require UEFI for GPT drives, this is a must and there is no

workaround.

In old BIOS mode, Windows 8/8.1 will not detect your GPT hard drives or partitions correctly. No booting, no Refresh Your PC or Reset Your PC until "UEFI

only" is set. Credits go to Sol for confirming this issue.

You can easily verify whether UEFI works correctly by opening Troubleshoot and Advanced Options in Windows 8/8.1 Advanced Startup

screen. If "UEFI only" is set, you'll see the UEFI Firmware Settings option listed. Thanks Sol for providing the screenshot:

"The drive where Windows is installed is locked. Unlock the drive and try again" and "Unable to reset your PC. A required drive partition is

missing" errors while refreshing or resetting Windows 8 or 8.1 installation, and error code 0xc000000e "A required device isn't connected or

can't be accessed" while booting.

Most of these errors appear on UEFI-enabled PC-s and indicate that boot information or file system is corrupt. See how to rebuild boot information for

Windows 8 and 8.1.

In some cases, Windows forgets the proper drive/partition order and tries to load files from a wrong one. Again, power off your computer and remove

power cord. Then disconnect cables from all hard drives except the one where Windows 8 or 8.1 resides, connect power cord and see if boot process

completes properly now.

Or, if Windows still works somewhat, try upgrading storage drivers and software using Intel's Driver Update Utility or find the driver software from AMD's

site. This often solves all problems.

Unmountable boot volume error (Blue Screen of Death) while starting Windows.



First, if your PC has multiple hard drives (including external USB drives!), power it off and remove its power cord. Then disconnect drive cables from all

hard disks other than the one where Windows is installed. Plug the power cord back in and see if this helps Windows to boot properly.

Second, enter BIOS/UEFI and set your disk controller mode (aka SATA mode, RAID mode) to Standard (aka Standard IDE or SATA, Legacy) instead of

AHCI or RAID (take note of the original setting first!). If this one fails, try other options until Windows starts properly.

Third, run a RAM check to verify that memory modules are working correctly. If errors are detected, reseat memory modules and re-run the check. If the

tests fail repeatedly, replace or remove faulty module(s).

Fourth, verify that hard drive/SSD SATA or IDE cables are seated properly. Unplug the cables and reseat them properly.

Fifth, enter Recovery Environment, run Automatic Repair, and then open Command Prompt to run chkdsk.

Unable to update firmware or drivers after push-button reset of Windows 8.1 device. This is because new value for driver or firmware dependency

in Windows 8.1 cannot be handled correctly. Download and apply the patch listed in Microsoft support article KB 2913760. Windows 8.1RT users can

install it using Windows Update only.

Options to try before using Recovery Environment in Windows 8 and 8.1

Always boot to Safe Mode at least once - this often repairs corrupted file system and essential system files.

If Windows is able to boot, use System File Checker and icacls.exe to repair corrupted system files.

While Windows is running, use free WhoCrashed for determining BSOD (Blue Screen Of Death) causes.

Reliability Monitor might also reveal faulty drivers or software.

Use Windows Update troubleshooter if your PC is unable to apply updates, or offers them repeatedly.

In case of Windows Store apps (aka Metro UI or Modern UI apps) failing to run or update, being unstable or requiring constant repairs, clear Windows

Store cache: open Start screen, type wsreset and click the result. Next, repeat the process, but right-click (or tap and hold on touch-screens) the result and

choose Run as administrator.

Use DISM (Deployment Imaging and Servicing Management) tool to fix Windows Component Store corruption as instructed in the System Image Backup

in Windows 8.1 tutorial - this often resolves a multitude of problems.

In case DISM RestoreHealth command fails with error 0x800f081f, then Non-destructive reinstall of Windows 8 or 8.1 is about the only option that fixes it.

Prerequisites of Windows 8 and 8.1 Recovery Environment

If Windows 8 or 8.1 is able to start and run, you can reboot right into Recovery Environment or use the Refresh and Reset your PC options.

To access Repair your computer/Recovery Environment (aka Limited Diagnostic State), you must have either Windows 8/8.1 installation DVD or Windows

8/8.1 Recovery Drive (USB) or System Repair Disc (CD/DVD) available in case Windows is unable to start.

To put Windows 8 or 8.1 installation media onto a bootable USB drive instead, see the Create bootable Windows installation media on a USB

stick guide on our sister site, www.winhelp.info. The tutorial also shows how you can download and create proper Windows 8/8.1 DVD from

Microsoft if you only have product key.

If you do not have the Windows installation DVD (e.g. Windows came pre-installed) or Recovery Drive/System Repair Disc, see the instructions on creating a

bootable Windows 8 or 8.1 installation media (DVD or USB).

Warning: do not use Windows 8/8.1 media for repairing Windows XP, Vista or 7 installations, or vice versa! You can only use the Command

Prompt option for fixing file system errors in older Windows installations.

If you can borrow a correct Windows 8 or 8.1 installation DVD from a friend, make sure you get the right version: you can only use 32-bit (x86) Windows disc

for repairing 32-bit Windows installations and 64-bit (x64) Windows disc for fixing 64-bit Windows installations!

Because Windows 8 and 8.1 Recovery Environment does not include RAM testing module, you should use Memtest86+ for checking if your computer's

memory modules are fine. Please do this before using tools provided in Recovery Environment - there is no point in repairing Windows if defective memory

will ruin it again soon.

The last resort is to use my Data Recovery CD/USB for fixing errors on disk or repairing Master Boot Records (MBR), but other options of Repair Your

Computer are unavailable. You can also use the CD/USB for recovering your files from the unbootable hard drive in case nothing else helps.

Getting into Recovery Environment in Windows 8 and 8.1 withoutinstallation media

In Windows 8 and 8.1, the good old F8 key trick for getting into Advanced Boot Options does not work anymore (but it can still be enabled manually). If

Windows is unable to start, you can get into new Startup Settings after Windows detects it was unable to start - click See advanced repair options

in Recovery screen, or after Automatic Repair fails - click Advanced options.



If Windows 8 or 8.1 is able to start and run, open Settings charm using keyboard shortcut WINDOWS KEY+I. The fastest way is to click Power and then hold

down SHIFT key while clicking Restart. This will reboot into Windows 8/8.1 Advanced Startup screen.

The longer way is to click Change PC settings in the bottom.

In Windows 8, click to open General tab of PC settings app, scroll all the way down to Advanced startup section and click Restart now.



In Windows 8.1, open Update & Recovery tab on the bottom left and then click Recovery tab. Click Restart now in the Advanced startup section.

This is how Windows 8/8.1 Advanced startup screen looks like.

Click Troubleshooting in Choose an option screen.



Booting to Recovery Environment with Windows 8/8.1 installationmedia or Recovery Drive/System Repair Disc

If your computer does not start from CD/DVD or USB drive, read about changing boot order.

After you boot your PC using Windows DVD or System Repair Disc, a black screen appears with gray text "Press any key to boot from CD or DVD". Press

some key on your keyboard (SPACE and ENTER are the most common ones ) within 5 seconds to launch Windows from the disc.

This screen will not appear while booting from USB Recovery Drive.

Windows will then load some files from the disc or drive, this takes some time.

In case you booted from Windows 8/8.1 Recovery Drive or System Repair Disc, Choose your keyboard layout screen appears. Click your keyboard layout,

or if one is not visible, click the See more keyboard layouts link until you see the correct layout.

If using Windows 8 or 8.1 installation DVD, Windows Setup dialog appears. Select your preferred settings from Time and currency format and

Keyboard or input method combo boxes. I suggest you leave Language to install to "English" here to better understand this article.



Click Next to continue.

Windows installation media users will then see a big tempting Install now button. Do not click it! Click Repair your computer in the lower left corner

instead.

Choose an option screen then appears. Click Troubleshoot.



Let's see an overview of the tools next.

Troubleshooting steps to take in Windows 8 and 8.1 RecoveryEnvironment

Please note that if you are using a wrong media here - e.g. Windows 7 installation DVD on Windows 8 PC, or 32-bit version of Recovery Drive/System

Repair Disc on 64-bit Windows - you can use the Command Prompt option only. While the other options are not disabled in the list, using these end with

error messages and might damage your broken Windows installation even more.

Step 1 - Automatic Repair and Startup Repair in Windows 8 and 8.1

Unless you started Windows 8/8.1 Recovery Environment from a failed Automatic Repair attempt, the very first option to try in case Windows is unable to boot

is the Automatic Repair (in Windows 8) or Startup Repair (Windows 8.1) that will check the condition of your hard disk and see if files needed to

launch Windows are present. The process takes from a few seconds to half an hour, depending on the problem.

Automatic Repair/Startup Repair can be used to fix file system corruption and Boot Configuration Data issues (for example, the 0xc000000f "The Boot

Configuration Data for your PC is missing or contains errors" error).

To access the option, click Advanced options in Troubleshoot screen.

In the Advanced Options screen, click Automatic Repair or Startup Repair.



Next, choose a target operating system by clicking on its button. In most cases, you should have only one Windows 8 or 8.1 installation visible.

Windows will then look for problems on hard drive(s) and verify that all required files are intact. This might easily take 10 or more minutes. Please stand by.



In case Automatic Repair was unable to fix problems, click Advanced options to access other recovery tools.

If repairs were successful, your PC will restart automatically.

Step 1.1 (optional) - use Command Prompt for fixing disk errors, restoringmissing system files, or preventing Automatic Repair from launching

If you do not have the correct Windows 8/8.1 installation or Recovery Drive/System Repair media, but you still need to check for and fix errors on disks, click

Command Prompt in the Advanced Options screen.



A black Command Prompt window opens on drive with letter X. It is a special temporary disk created entirely in the Random Access Memory (RAM) of your

PC. No hard disk space is used for this drive.

First, we need to locate the drive where Windows is installed. Most probably this is a drive with letter C, D, E or F.

Type echo list volume | diskpart and press ENTER. This will display all drives/volumes/partitions available. You need to use this command to

verify that no partition/volume is listed as having RAW file system type.

Ignore all volumes that have "CD-ROM" written in Type column.

The volume that has "System Rese" (part of "System Reserved") written in Label column, is the recovery partition, and it typically has drive letter C in Ltr

column. Such partitions are usually small in size - about 300 to 350 megabytes (MB). You should check this partition for errors, because normally Boot

Configuration Data (BCD) is stored there.

Please note that not all computers have the recovery partition.

So, in the example above, the Windows 8 partition has drive letter D (note the Ltr column). You can also use the Size column for verifying that you have

located the correct one. Do not mix up megabytes (MB) and gigabytes (GB).

To double-check the Windows drive letter, type bcdedit | find /i "OSDEVICE" and press ENTER.

This outputs something like osdevice partition=E: where the very last letter is your Windows/system drive letter. It might be some other letter in your case.

In case your Windows partition showed up as RAW in Fs (File System) column, you still need to run chkdsk and take note of the results. Normally, Windows

partition should list "NTFS" in Fs column.

Now type chkdsk : /F /X and press ENTER. Replace with the letter of drive where Windows is

installed (or the drive that has files badly messed up), for example chkdsk d: /F /X or chkdsk c: /F /X.

This command will find and repair errors on the partition/volume (the /F switch) and if required, unmount it first (the /X switch).

If you want to run a full disk check with recovering data from unreadable clusters, use the chkdsk : /R /X command instead.

Note that the exhaustive test might take several hours to complete.



The process might take quite a while (up to an hour without the /R switch, and several hours with the /R switch). After it is completed, verify that there is a line

stating "Windows has checked the file system and found no problems" in the report.

If there were errors on the volume, repeat the last command (press ARROW UP key to recall the last command) until the no problems message appears.

Please check other partitions, especially the 300-350 MB "System Rese" one for errors, too. If you have more than one hard drive installed or more than two

volumes/partitions, do not forget to run disk check on these - this might solve your problems.

If Windows partition was listed as RAW in diskpart and you see the "A disk read error occurred c0000185" message before chkdsk completes, you need

to either reseat or replace hard drive cable (turn off your PC, disconnect power cord, then unplug and replug the SATA cable both on motherboard side and

hard drive/SSD side). If your PC case is very dusty inside, clean it with compressed air before reseating or replacing the cable.

Another method that works surprisingly often in this case, is resetting BIOS/UEFI to defaults. Reboot your PC and press F1, F2, F10, F12 or DEL (aka

DELETE) key to get into BIOS/UEFI (the correct key is usually displayed on screen first). On some computers you might have to press ESC key to see options

list. Then find and use the option that is similar to "Restore defaults" or "Load defaults". Intel motherboards have F9 key for this purpose.

Please note that you might encounter the "Windows failed to start, File: \Boot\BCD, Status: 0xc000000f, Info: The Boot Configuration Data for your PC is

missing or contains errors" screen after resetting BIOS to defaults. This can be easily fixed with Automatic Repair/Startup Repair or bootrec as shown here.

If reseating/replacing SATA cable and resetting BIOS/UEFI to defaults does not help, run Memtest86+ to verify that RAM modules are working correctly. If a

RAM module has errors, remove or replace it.

Ignore any failure messages about event log: this is because event logs are not available in Recovery Environment.

After chkdsk repairs file system errors on all volumes, close Command Prompt by clicking the X mark on the top right. Click Continue in the Choose an

option screen to try starting Windows normally and see if the problem has been solved.

If no disk errors were found, read on.

Recover missing or corrupted system files with SFC

You can also try restoring missing system files using the SFC (System File Checker) tool. This is useful in cases where Windows boots up, but all you

see is black screen with mouse pointer and keyboard shortcut CTRL+ALT+DEL does nothing.

Type sfc /scannow and press ENTER. Let the scan finish, it will take about half an hour.

If you see the error message "There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again.", use alternative

command sfc /scannow /offbootdir=C:\ /offwindir=D:\ (replace D:\ with the correct drive letter for your CD/DVD or USB drive if

necessary).

Prevent Automatic Repair loop

If your Windows 8 or 8.1 PC is stuck in Automatic Repair loop, try disabling the feature via Command Prompt. Type bcdedit /set {default}

recoveryenabled NO and press ENTER Key. If the message reads "The operation completed successfully", then Automatic Repair will not appear until

you re-enable it with the bcdedit /set {default} recoveryenabled YES command in an elevated Command Prompt.

Close Command Prompt window and and click Continue to see if this helped to get your Windows 8 or 8.1 PC running correctly again.



Step 1.2 (optional) - temporarily enable the F8 key for getting into Advanced BootOptions menu at computer startup

Because Windows 8 and 8.1 have no support for F8 key by default, you might be unable to get into Safe Mode or Low-resolution video mode for

troubleshooting unless Windows starts properly. Somehow Microsoft couldn't foresee this vicious circle happening to many users.

Luckily, you can enable the good old trick in the Command Prompt window described in Step 1.1 above. Please note that legacy boot options should not be

turned on forever because they can cause trouble on UEFI systems. This is just a temporary workaround.

In the black Command Prompt window, type bcdedit /set {default} bootmenupolicy legacy and press ENTER key. You should see "The

operation completed successfully" message after this.

Close Command Prompt window and restart your computer. Pressing F8 key repeatedly before Windows 8 or 8.1 starts loading should now bring up the

older Advanced Boot Options menu.

To revert to the newer Modern UI version of troubleshooting tools, open elevated Command Prompt while Windows is running (use WINDOW KEY+X to open

Quick Links menu and click Command Prompt (Admin)). You can also boot from Windows installation media or System Repair Disc/Recovery Drive and

open Command Prompt in Recovery Environment.

Type bcdedit /set {default} bootmenupolicy standard and press ENTER key.

Close the Command Prompt window and reboot your PC. Now your computer uses the Modern UI boot options again.

Step 1.3 (optional) - repair Boot Configuration Data with bootrec

If Windows 8 or 8.1 BCD (Boot Configuration Data) becomes corrupt after a crash, power outage or some other reason, you'll encounter the "The drive where

Windows is installed is locked. Unlock the drive and try again" and "Unable to reset your PC. A required drive partition is missing." errors while refreshing or

resetting Windows 8 or 8.1 installation, and error code 0xc000000e "A required device isn't connected or can't be accessed", 0xc0000001 "A required

device isn't connected or can't be accessed" or 0xc000000f "The Boot Configuration Data for your PC is missing or contains errors" while booting.



Please note that Windows partition must be listed as NTFS (or FAT/FAT32 in very rare cases) in Fs column of echo list volume |

diskpart results, otherwise there is no point in running the following commands. See how chkdsk results can sometimes reveal the cause for

Windows partition listed as RAW.

Type the following commands and press ENTER after each one:

bootrec /fixmbr

bootrec /fixboot

bootrec /rebuildbcd

If you see a prompt to add one or more detected Windows installations after the last command, press A and then ENTER on keyboard. This means that BCD

has been fixed successfully: close Command Prompt and restart your PC.

But in many cases, the bootrec /rebuildbcd command results in 0 total identified Windows installations instead. The screenshot below illustrates this

situation:

To resolve this problem, you first need to locate the drive where Windows Boot Manager resides. In Command Prompt window, type bcdedit and press

ENTER. Locate the entry Windows Boot Manager (usually the very first entry with identifier {bootmgr}) and see the second line, device. In this example, the

line reads "partition=C:", meaning that Windows Boot Manager is on the partition/volume with drive letter C. In many cases, the drive letter might be

something different.

Run the following commands in case your PC is in legacy boot mode (uses BIOS, or is set to legacy boot). If necessary, replace drive letter "C" with the

previously detected drive letter in the first two commands.

If the first command fails with "Path not found" error, your PC is not in legacy boot mode, or you used a wrong drive letter. Do not worry, try the UEFI boot

mode commands instead, or double-check the drive letter from bcdedit output.

attrib C:\Boot\BCD -h -r -s (removes hidden, read-only and system attributes from BCD folder)

ren C:\Boot\BCD BCD.old (renames BCD folder to BCD.old)

bootrec /rebuildbcd (retries the rebuild)

In case your computer is in UEFI boot mode (the commands above resulted in "The system cannot find the file specified" error), use the following commands

instead (replace drive letter "C", if necessary):

attrib C:\EFI\Microsoft\Boot\BCD -h -r -s (removes hidden, read-only and system attributes from BCD folder)

ren C:\EFI\Microsoft\Boot\BCD BCD.old (renames BCD folder to BCD.old)

bootrec /rebuildbcd (retries the rebuild)

Now, in the Add installation to boot list line, type A and press ENTER. The new BCD is ready, close Command Prompt and restart your computer.

Step 2 - System Restore

The next step is to try System Restore from Advanced Options screen. This works only while using the correct Windows installation or System Repair

Disc. Using Windows 7 media on Windows 8/8.1 installation (or vice versa) ends with an error message about no available Restore Points.

System Restore will literally turn back time for your PC: while your documents and files will always remain intact, all programs or drivers installed after the

selected Restore Point might disappear and must be reinstalled. Also, if you changed your Local Account password recently, it might be reverted to the

previous one by the selected Restore Point.

Please note that this System Restore cannot be undone (but you can still restore another Restore Point later).

Hi Team Winhelp, this is really help forum, i did step 1.1 in my notebook but find some trouble here (i dont know how to post an image here) this is the result of my

"echo list volume | diskpart" [IMG]http://i57.tinypic.com/2z3tjk0...[/IMG] there is 7 disk volume (0-6) but volume ## 3,4,5,6 doesnt have drive letter and this is result

of my chkdsk drive C [IMG]http://i62.tinypic.com/2ztj7kj...[/IMG] i did it 4 times but the result always show "1208 KB bad in bad sectors".

My Question is :

1. How to run chkdsk command for the drive that doesnt have drive letter in my case volume ## 3,4,5,6 ;

2. What is mean of the result chkdsk drive C that always shown "1208 KB in bad setors" and what should i do? reset the PC to factory setting?

3. How to know my notebook is bootable or non-bootable ?

Thanks team, thats all my problem so far, please give me some sollution.

Oh ya my notebook failed update from windows 8 >>> windows 8.1 (action centre always show "solve a problem with intel Rapid Storage Technology" even i was

installed it)

Hi!

Have you updated Intel Rapid Storage Technology software lately? Scan for driver and software updates using this Intel tool at

http://www.intel.com/p/en_US/s...

Answers:

1. Type "diskpart" without quotes and press Enter. Type "select volume 3" without quotes and press Enter. Type "assign" and press Enter. This assigns

drive letter to the volume. Repeat "select volume " and "assign" commands for volumes 4, 5 and 6. Type "list volume" without quotes,

press Enter and take note of the new drive letters. Type "exit" and press Enter to quit diskpart. Now you can run chkdsk on the volumes 3-6 using their new

drive letters. To remove the drive letters, run diskpart again, select volume 3, type "remove" without quotes and press Enter. Repeat the same procedure

for volumes 4-6 and exit diskpart.

2. Resetting your PC does not resolve bad sectors on a drive. Bad sectors are unreadable parts on your computer's hard drive, and this means that the

hard drive may fail soon and you might lose all data on it. If your notebook has a valid warranty, you can get a replacement drive for free. I strongly suggest

backing up your hard drive to some external drive, please see https://www.winhelp.us/configu... or https://www.winhelp.us/system-... for instructions.

3. Your notebook is bootable when Windows 8 starts and you can sign in to your account. Non-bootable means that Windows does not start or crashes at

startup, and you cannot sign in.

Hi Zia! What is the exact error you are trying to resolve?

\Device\HarddiskVolume2 is the Volume 2 in the Diskpart List Volume output, or drive letter D according to your post.

But looking at volume sizes, boot manager should probably be on volume 5 (drive letter H) instead.

You might want to try the following commands:

1. diskpart

2. select disk 0

3. select partition 5

I am getting Inaccessible_Boot_Device on a rig with BIOS boot. It happened during reboot from a Winderz update. Chkdsk reports no errors. I can delete and

rebuild the bcd, it finds Winderz and I type "A", but still won't fire up afterward. On my 3rd time through after rebuilding I did a scanos which found no OS, seems

like it should have been able to find it after the rebuild? Any other ideas to try? I hate to reinstall, the number of programs and updates to the updates for the

updated updates is a full day of monotonous boredom but this is a work rig so time is more critical than my enjoyment.

Hi Jeff! Go into BIOS setup and write down the current SATA emulation/disk controller mode. Most usually it is either AHCI/Enhanced or IDE/Standard. Now

switch the mode to the alternate value (for example: if it was IDE by default, set it to AHCI, or vice versa), exit BIOS setup saving new values and retry

booting.

Second option is to boot from Recovery Drive or Windows installation DVD and run Automatic Repair/Startup Repair in Troubleshoot, Advanced Options.

Hey There,

Thought I would be a good netizen and follow up on this. Switching controller mode did not help and I was out of time for trying to repair so did a

complete re-install. Once installed, updated and configured I used other articles on your site and learned how to create an image and several other

steps I could take so that I will be better prepared next time. I expect that I could now have a complete failure and be back up and running in a couple

hours instead of a couple days with in the worst case scenario less than a single day's work/email lost to the gremlins. Thank you for sharing your

knowledge and attention to detail in your writing it was a big help in developing and implementing the strategy I now have. I don't bookmark many

things but your site has made the cut, and those bookmarks are now backed up daily.

I have refreshed my computer several times now and it will work for a day or so and then either shut off on its own or when I turn back on my toshiba laptop I get

stuck in the automatic repair loop again and again. tried some of the steps above but honestly most of this is like Greek to me. I think I am making a recovery

image disk now. Not even sure what to do with it once it is done. Could you please talk to me like I'm 8 years old and help me fix this problem. I have read a 100

different ways on line on how to troubleshoot this but don't understand most of it. I'm sorry but I'm ignorant on all this and just want help in fixing it . I don't even

understand how this is happening? Is it caused by a virus?

Hi Michelle! Is your laptop getting hot before shutting down? Please use free WhoCrashed to check if this is a temperature-related problem:

https://www.winhelp.us/analyze...

To check your laptop for viruses and other malware, use free Malwarebytes Anti-Malware. See https://www.winhelp.us/install... for installation instructions

and then run Threat Scan as instructed here: https://www.winhelp.us/malware...

First, thanks for your quick response. Ok I did the above steps recommended. No valid crash dumps and I downloaded the Malwarebytes and

performed scans. Threat scan said completed success, no malicious items found. So I then removed the Malwarebytes and reloaded my Vipre

Internet Security since it seemed it has been doing its job given the successful scan Malwarebytes and I've never had a problem with vipre the past

few years I've had it. So all seemed to work well for a few hours then internet lost connection and a wireless keyboard I am using quit working all of

a sudden. I been using a netgear wireless adapter that plugs into USB the past few weeks because I kept having connection problems with the

wireless"whatever it's called" on my laptop (while other devices like my ipad and phone never have internet connectivity problems). My wireless

keyboard also is plugged into USB . Anyhoo, I had to restart my laptop and I just knew it was going to go back into that stupid automatic repair loop

and it did, but I got a sad face blue screen for the first time that said "PC ran into a problem and needs to restart...if you'd like to know more, you can

search online later for this error:DRIVER_POWER_STATE_FAILURE .... So now I don't know what to do, maybe start drinking- but it might be too

early in the day for that. I am in the troubleshoot screen and don't know if I should refresh computer again, type in some magical commands or

what. I have read that this automatic repair loop could be caused from an automatic windows update 8/8.1 which my computer may have done one

last week when all this started, but not sure and I also read USB issues may be connected to this repair loop, but again, I'm clueless. Also I do not

have my windows 8 disc and can't get to it for another month and I tried doing a system restore image disc- not even sure what that is Or why I

should do it, but read that I should and that was a failure. I just need to fix it and don't know what to do at this point. I have moved past frustration and

to tears and am pretty close to the grief stage. Can you help me at all for what I could try next? I do think I will have that glass of wine now though.

The "DRIVER_POWER_STATE_FAILURE" error has many possible causes, I suggest going to your laptop manufacturer's support site first

and updating all drivers and manufacturer-provided software for your laptop from there.

You can also use SlimDrivers Free ( https://www.winhelp.us/update-... ) for updating drivers, but manufacturer-provided ones are preferred.

Hi, I encounter an error code when trying to create a restore point 0x80070005. What can I possibly do to solve this problem? Thank you!!

Reply

www.winhelp.us a month agoMod > Alfrd

Hi Alfrd! Do you have update rollup from May, 2014 ( http://support.microsoft.com/k... ) installed?

Second, use keyboard shortcut Windows Key+W to open Settings Search. Type "services" without quotes and click "View local services" in the results.

Make sure that "Microsoft Software Shadow Copy Provider" and "Volume Shadow Copy" services are set to Manual startup, not Disabled.

Third, what is your anti-virus solution? Norton and BitDefender are known to cause this error.

Reply

Alfrd a month ago> www.winhelp.us

I update my drivers and everything is alright except the installation of AMD Radeon so I just do the Factory Restore and after that I uninstall

unnecessary apps including my built-in Mcafee Antivirus using their removal app. After uninstalling Control Panel prompt me about Windows

Defender so I turn it on after that I tried to create restore point but the error preventing e to create one. I don't have any other software installed at

that time except for Firefox 35 and Chrome 40 also I already check "Microsoft Software Shadow Copy Provider" and "Volume Shadow Copy" and

they are both set to manual.

Open File Explorer using keyboard shortcut Windows Key+E.

Open the View tab and click "Options".

In "Folder Options" window, open View tab and clear the "Hide protected operating system files (Recommended)" check box. Click Yes

when you are prompted to confirm the change.

Click OK.

Open drive C in File Explorer. Right-click the "System Volume Information" folder and click Properties.

If the Read-only attribute is checked, uncheck it and click OK.

Retry creating a restore point.

Hi ahmm I'm just wondering because I notice that every time that I perform a Factory Restore my primary Hard Disk reduces its free space

by a couple of gigabytes approximately 5GB. Does Windows 8 restore some files from the previous account and is it possible and safe to

delete them? thanks a lot XD

Reply


Use Disk Cleanup ( https://www.winhelp.us/free-up... ) for this task, the entry is probably called "Previous Windows installation".

Thank you so much it solve the problem and save me a lot of time because my other option was Factory Restore that take almost an hour

When i try to make the command attrib C:\Boot\BCD -h -r -, it says C:\Boot not found, what can i do?

Reply

www.winhelp.us a month agoMod > #TimBeta

Hi TimBeta! Run "echo list volume | diskpart" without quotes and see which drive letter your Recovery Partition has (it probably has "System" or "System

Reserved" for label). Then replace "C:" with the Recovery Partition drive letter. For example, if the partition has drive letter D, then type attrib D:\Boot\BCD -

h -r -s

Hi although I manage to restore my laptop to factory default now I have a problem because my explorer crashes every now and then I sent to your mail the

Your crash dump shows that the reason is in the QtCore_Ad_SyncNs_4.dll file. This is a part of AutoCAD, their support forum suggests right-clicking

AutoCAD icon, unchecking "Start Autodesk when I log into Windows" and rebooting.


How will I exactly do that? I already done that after the system restore, I disable unnecessary programs on startup https://onedrive.live.com/?cid...

but every time I log in some processes always persist. I always saw some processes on my task manager that I don't know how to prevent from

automatically starting like Autodesk Content Service, Microsoft Upload Center, Dell Backup and Delivery Toaster and Update Launcher, Dell Digital

Delivery Windows Service. Power DVD, QuickSet etc. I also tried using services.msc to set automatic processes to manual like the Autodesk

Content Service but when I start Autocad more service/process associated with it pops up on my task manager sucking up my CPU, Memory &

Hi Aron! Section 1.3 is not the correct solution for this. Please boot into Recovery Environment as described in this article, and then follow instructions in

thanks, I tried everything on this page. I cannot recover windows 8, I can't restore or re-install windows either. I spent 40 mins on the phone with

ASUS tech support and they of course want me to mail the laptop in and the warranty is expired. I took the hard drive out and copied all my user

files to my windows 7 laptop. I have a device that i can connect a hard drive and connect via USB to a computer. I am basically just trying to re-

install windows which seems to be almost impossible. I can access a command prompt, when i try to reinstall windows I get an error message

"unable to reset your pc a required drive partition is missing". When i try to restore i get an error message "the drive where windows is installed is

locked. unlock the drive and try again". My laptop is an ASUS S500c for the record.

What is the output of the "echo list volume | diskpart command" - is any of the partitions listed as having RAW file system? This is the one

you need to run "chkdsk /F /X" on. If the partition does not have a drive letter assigned, type "diskpart" without quotes and

press Enter.

Type "list volume" without quotes and hit Enter.

Note the volume number for the volume with RAW file system.

Now type "select volume " without quotes, replacing with the volume number from previous step. For example, "select

volume 2". Press Enter.

Type "assign" without quotes and press Enter.

Type "exit" without quotes and press Enter.

Now this RAW volume has a drive letter and you can use it for running chkdsk. Post exact error codes and error messages during or in the

end of the process, ignoring only the status 50 about Event Log.

Thank you very much for your help. Mission accomplished. The volume with the raw file system is now "D", I ran chkdsk how you said and i

get an error message, "The drive, the path, or the file name is not valid".

I basically retried this whole guide and i set drive letters for all the volumes and ran chkdsk, I still can't boot into safe mode, I can't restore or

re-install windows. I missed some steps the first time but still same issue. I didn't do the memtest yet, I assume that may be the cause?

When you boot your PC, does it restart by itself or does it show some error code/message? If it restarts too quickly, enable the "Disable

automatic restart on system failure" option from Troubleshoot -> Advanced Settings -> Startup Settings menu. Then post the exact error

message and code.

0xc000021a was the error code, then it reboots, then i get a recovery screen with the error code 0xc0000001

Go to Command Prompt and enter the following commands:

1. dism /image:C:\ /cleanup-image /revertpendingactions

2. cd C:\Windows\WinSxS

3. move pending.xml pending.old

The last one might fail if the pending.xml file does not exist. Now reboot your computer and see if it starts.

First of all thanks you very much! I ran the first command and got Error: 0xc0000135 an error occurred while attempting to start the

The solution to recovery screen with code 0xc0000001 seems to be running "bootrec /rebuildbcd" without quotes in Command Prompt. It

might work now when all your partitions are accessible (volume 5 was unreadable before).
