Well, here is the latest. They system totally crashed. I couldnt boot from C:, even into safe mode. I could not even boot from a clone of C I made a few months ago. System recovery or system restore also crashed. Repair disk also didnt work.
Finally, I was able to get the machine to boot from the original Win 10 DVD. Unfortunately that is a very old version of Windows. I cant even install my gpu drivers because it is so old. I am running update after update, hoping to finally get to 22H2. (I had to reformat C: to get Windows to reinstall from the DVD). So we will see. Still hoping to get Win 22H2 to install and decide what to do from there.
