So, I've been trying to install Elementary OS Freya for a while now and realised I needed the 32 Bit version because Mac Minis have a 32 bit limitation for kernels. But when I tried the USB method, the mac mini wouldn't boot into the USB. So I followed the next steps, to use a disc; only thing is, it wouldn't boot with the disc burnt with the iso.
Edit: When trying to use the disc, it would get stuck on a white screen... Had to force reboot.
