Windows 10: Bootloop after Windows 11 Update

I was prompted to do an update for windows 11, but after restarting my pc it got stuck in a bootloop with an BSOD. Following things happen, first it tries to automatically reset changes made and after a few minutes i get a Bluescreen with SYSTEM_SERVICE_EXCEPTION and Ntfs.sys. I also cant do an automatic Repair as i tried multiple times but it wont boot into the screen where i can go into safe mode. Any idea on how to fix this?

Windows 11 stuck in bootloop

Perform a hard shutdown two times during the Windows boot screen. On the third time, Windows should boot to the recovery environment, something like this.

Choose Options (winre.azurewebsites.net)

If you get a screen that says you would need to use Recovery tools, you would need to use another computer to create a recovery/installation media. You may also need to use Installation media if Windows Recovery environment says your password is incorrect.

Boot from the USB Flash drive-Make sure you have disabled Secure boot/Fast boot in BIOS Settings and changed the boot order if required.

When you have successfully booted from the Installation media, click Repair your computer at the first screen after choosing the keyboard layout.

1. Use Startup repair: The first option you can try is to use Startup repair, which automatically detects problems and fixes them. Depending on the severity of the problem, it may or may not be successful.

2.Uninstall Updates

• The second step you can try is to uninstall the latest updates if Windows 10 fails to start after installing updates.
  
• Choose Uninstall Updates.
  
• Uninstall the update based on what was installed – a feature update or a quality update. Usually, the former is responsible.
  

3.CHKDSK:

If uninstalling did not help and is unrelated, the next step is to try using a Disk Check.

• Choose Command Prompt in the list of troubleshooting.
  
• Get the Current Windows Installation drive letter, which is either C, D, or E, Type BCDEDIT, and Press Enter. Note the letter.
  
• Enter the command given below:
  chkdsk X: /f /r (Replace X with the Current Windows Install Letter)
  
• When done, you would see the output and restart the PC to check.
  

4.Another try you can give to fix is SFC SCANNOW through Offboot switch. For this follow the steps below:

1. First, find the Windows Install drive letter using BCDEDIT command.
   
2. Then, try entering the following command:
   sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
   
3. After the scan completes you would see the results.
   
4. You can also try using DISM: dism /image:C:\ /cleanup-image /revertpendingactions
   

5. Reset this PC or clean install.

The last Step is a Reset. The catch with Reset is, all applications would be removed and files would be kept(you would be presented with the option to erase everything). Also, for this step, A healthy Reset Image is required, which maybe would be affected by corruption. If you are using an Installation media, you can do a clean install after rescuing your files.

Windows 10 Anniversary Update Bootloop

I successfully applied this workaround to install update 1607:

Windows 10 Upgrade reboot loop or error 0xC1900101- 0x20017

Workaround

The workaround is to not use the “English (Europe)” locale. Use the following steps to change this for all accounts:

• Go to Regional Settings
• Change the Format to English (United States) – or anything other than “English (Europe)”
  • You can also select a different language or change any of the date/time formats per your needs
• Select the Administrative tab and hit Copy Settings
• Select the bottom two checkboxes and hit OK.
• Reboot the PC and start the Windows Anniversary Update. Windows should upgrade.

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.
