I'm involved with Windows 11 insider and suspect the latest update may have caused issues. My PC worked normally for a while before lagging, freezing, and displaying the WHEA_UNCORRECTABLE_ERROR message. After installing Windows via USB with a custom setup, I now have two versions on my C drive and encounter the same error when trying to boot both. I checked hardware by removing the drive from another functioning PC and ruled out physical problems. Any suggestions on preserving data or wiping everything?
Retrieve your files by placing the C drive on a computer with a functional boot drive or OS, then moving to your user directory. (This approach applies only when BitLocker is turned off or you possess the key.) Alternatively, consider a fresh installation to erase faulty setups and start over.
If you're a Russian Roulette player, you might be puzzled by the fact that you die about once every six tries. A broken boot sector on your drive won't fix the issue, so simply installing new windows there won't work. You need to make a fresh boot drive to reach your existing storage.
It's a risk, and I won't proceed without a reliable boot backup drive.
