Windows 10: Unable to boot after upgrading to Windows 11

Hello, I just attempted to upgrade to Windows 11 on my brand new PC i just built and now when I attempt to boot I get a black screen with the options to boot windows 10 or 11, either selection leads to the PC crashing, rebooting and going back to the same screen. Everything was working fine prior to update.I went to advanced options, and hit "repair your computer" I've attempted to launch in safe mode, reset the PC, restore to my latest backup version, and uninstall any recent updates, but all of the above just leads to a bliue screen with the error WHEA_Uncorrectable_Error,, any suggestions?S

:)

Hi Samid,

Thank you for posting your query on Microsoft Community.

I suggest you check if you are able to boot into Windows Recovery Environment using installation media. Follow the steps provided below and check.

• • Insert the installation USB and boot Windows 10 from it.
  • In the ‘Windows setup’ page select the ‘language to install’, ‘Time and currency format’ and the ‘keyboard or input method’ and click on ‘next’.
  • Click on ‘Repair your computer’ and select ‘Troubleshoot’.

Check if you are able to boot to this window. If you are unable to boot to this window, I suggest you to contact the manufacturer and check.

Upgrading to windows 11

I have a few questions about windows 11...

1. How many GB it is? when my pc suggested the upgrade yesterday, it said it's about 4GB just want to be sure.
   
2. I'm using a windows 10 pro so if I upgrade, will it upgrade to a windows 11 pro?
   

 

Windows 11 upgrade failed.

Thanks.

The BCD or the EFI boot partition's file system is corrupt. Rebuilding the EFI boot partition fixes this issue.

If you need step-by-step assistance in this regard, boot into WinRE Command Prompt.

Then run:

• mountvol y: /s
  
• bcdedit
  
• diskpart
  
• list vol
  

For each command, photograph the screen and upload it to OneDrive.
