On the computer in my signature, I've been trying out a few different operating systems, and I had success doing it before on this machine, but then for whatever reason it stopped wanting to boot from USB to install the OS (don't have an optical drive). The HDD and USB flash drive both used to show up in EFI boot sources, but then they randomly moved into legacy boot sources in the BIOS with no way to change them back. I reset the BIOS back to stock with the same issue. I could hold down F9 at boot and force it to boot off the flash drive, but it the screen just goes blank with a flashing cursor.
I removed the CMOS battery for about 10 minutes, and now when I boot it I get a message about "161 real time clock power loss" so I have to go back into the BIOS to set the defaults which I've done, but this happens every time I start it up and I still can't get it to load the OS. It just beeps every time I start it telling me about the CMOS, and even after saving the default settings this still happens.
