Cant install windows 10 from USB drive, cpu is i7-7700k

Hi, will start describing the situation.

My pc is very old, its a gygabyte GA-Z270-HD3P. I want to use it again since i7 is quite decent even for 2022. The issue is i stopped using it because of some unkown issue no one ever helped me with, now when i restarted it, it keeps giving me this error: exception scope invalid or Kmode  exception not handled after saying "preapring for automatic repair".

I thought "okay, lets just install windows from 0 using a USB drive". However the result, with both windows 11 and windows 10 is "unsupported processor".

I have not found ANY issue stating that windows 10 cant be installed on my CPU, and even though there are many vids and threads helping install on unsuported CPUs, i cant even do that since i cant get out of bios.....Its in a constant loop of restarting itself, entering repair, and giving the error.

Does anyone have any idea how i might solve this? Thank you
