My computer is an old quad core, and I don't think it's EFI. Despite that, two of my drives are GPT and Win8 refuses to install for this reason. Currently running Win7 installed via ISO/Rufus, and I have Linux Mint on another HD installed via the same method, so I know it works with other O/S's, but cannot figure out why it won't work with Win8.
I've tried varying Rufus several different ways and experimentally changed several switches in BIOS to no result. Either Win8 refuses to install because the partition is GPT, or the USB drive is not even recognizes and the whole system hangs on boot.
Is there something different between Win7 and Win8?
