My PC updated on its own and now I can't boot

[Garrzilla]

I am part of Windows 11 insider and I guess a new update bricked my PC. I woke up to my PC recently updated, everything was fine for an hour. Then it started to lag, eventually froze and started a loop of the WHEA_UNCORRECTABLE_ERROR BSOD. I load up a USB with Windows 11, do a custom install of Windows, select my C drive and try installing another instance of Windows. Now I have 2 installs on my C drive, and when I try to load both I get this same error "The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. The install Windows, click "OK" to restart the computer and then restart the installation."

 

I also ruled out hardware by removing the C drive and putting it into another perfectly working PC. Any ideas on saving my data or do I need to wipe it all?

You should be able to get your data back by installing the C drive into a computer that has a working boot drive/OS, and navigating to your user folder. (This method works only if you have BitLocker disabled or if you have your BitLocker key).

 

Then I'd suggest a clean reinstall (wiping the defective installs and reinstalling Windows).

If you're a Russian Roulette player don't wonder why you get killed 1/6 of the time  

 

Boot sector on your drive may be broken, so creating new windows install on it won't help, you have to create another boot drive to access your current drive

I mean it's a risk, and I won't do that without a stable boot backup drive
