This is nuts. I've configured BIOS/UEFI, Fast Boot, Legacy and Secure Boot in so many different ways and NONE of them change a damned thing.
So far not one 32 bit live CD or live DVD distro will boot (including Ubuntu 12.04, 12.10 and 13.04). The only Live media to boot have been 64-bit editions of Ubuntu 12.04/12.10/13.04. And a couple 64-bit Ubuntu-based distros. Other than that, nothing boots. Not Fedora, not OpenSUSE, not SolusOS, not Fuduntu, not PCLinuxOS, not Manjaro, not Gparted...
UN FREAKIN' REAL.
