Lenovo Tiny M73

I had this running Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina, then tried upgrading to Big Sur which kind of worked, wifi did not work.

Decided to reinstall Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina and for some reason now I can't

No matter what I do, I cannot boot off the USB flash drive.

I reset the BIOS using the jumpers on the motherboard, rest to defaults in the BIOS a dozen times or more, nothing I do can get it to boot to the USB flash drive which I know works, I have used it to boot on another computer and it worked fine.

I am really at a loss as to what to do next.
