Seems like you have tested most of the stuff what about the hard drive. It works fine if you run from the usb with something like knoppix but not if you run from the drive? Your output doesn’t mean anything to me I just hadn’t heard you say anything about the hard drive. Or verify all was well booting from another source.

I plugged in a live USB. It loads the grub but if I try to load the live version or comparability version it stops during loading and reboots to BIOS
