Hi, I am trying to install Windows XP on my 2008 PC. I used rufus on my main PC to mount the Windows XP .iso onto my USB, but I am clueless how to get my USB key to be recognized at all by the older system. I've looked this up online, and I think it all has something to do with MBR vs. UEFI. The old pc had Windows 10 on it, which installed the latest BIOS for the Phenom ii, so I think I just need to find a super old BIOS file to replace the new one so that it will allow the Windows XP USB to start.
Does anyone know what I'm talking about? The system is from 2008, so it can definitely physically run Windows XP, the trouble is all the updates hating on W-XP. Any advice appreciated.
