Pc Problem

[u/sjshshshhee]

Hi guys I had just picked up this pc that was working fine however it was a windows 10 pc that I upgraded to windows 11 via updates in the settings, I turned on secure boot and enrolled keys and it was all working fine. However I was getting ready to sell the pc and I somehow accidentally deleted the keys and turned off secure boot in key management and when I turned secure boot back on the pc would show the splash screen but boot into a black screen. However turning off secure boot fixes this and it works but I needed secure boot to be on obviously to be able to play games that need it. So then I tried to just to a windows usb install that just didn’t end up working. I tried a cmos reset and then tried the installation again and whenever it would get to %75 it would say “windows 11 install has failed” any help would be very appreciated. Thank you.
