Repair Windows 8 and 8 1 Solution
Repair Windows 8 and 8 1 Solution
| ||||
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.
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 enterBIOS/UEFI and set your disk controller mode (aka SATA mode, RAID mode) to Standard (aka Standard IDE or SATA, Legacy) instead ofAHCI 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 Intels Driver Update Utility (Internet Explorer installs ActiveX control, other browsers require Java) or find the driver software from AMDs site. This often solves all problems. - 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 changesbutton. - 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, youll 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" errors while refreshing or resetting Windows 8 or 8.1 installation. 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 Intels Driver Update Utility (Internet Explorer installs ActiveX control, other browsers require Java) or find the driver software from AMDs site. This often solves all problems.
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.
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.
If you do not have the Windows installation DVD (e.g. Windows came pre-installed) or Recovery Drive/System Repair Disc, grab the 90-day Windows 8 Enterprise evaluation DVD from MSDN (you need to sign in with your Windows Live ID).
Warning: do not use Windows 8/8.1 DVD for repairing Windows Vista or 7 installations, or vice versa! You can only use the Command Prompt option on the wrong disc to fix file system errors.
If you can borrow a correct Windows installation DVD from a friend, make sure you get the right version: you can only use 32-bit Windows disc for repairing 32-bit Windows installations and 64-bit 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 computers 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 ofRepair Your Computer are unavailable. You can also use the CD/USB for recovering your files from the unbootable hard drive in case nothing helps.
Getting into Recovery Environment in Windows 8 and 8.1 without installation media
In Windows 8 and 8.1, the good old F8 key trick for getting into Advanced Boot Options does not work anymore (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 and you can use at least one monitor, 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.

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.

Booting to Recovery Environment with Windows 8/8.1 installation media or Recovery Drive/System Repair Disc
If your computer does not boot from CD/DVD or USB drive, read this article on how to change boot order.
After you boot your computer 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.

) 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.
