To include win7. Win8, from usb or dvd, will install and boot in efi mode with secure boot and fast boot enabled/disabled. Win7 will install in "efi-ish" mode but needs launch csm enabled. I only list the win7 issue to show that it is not isolated to linux. Ubuntu, fedora, linuxmint, basically any linux distro I found (x64) that supports efi will not boot even in live mode efi. The same media for the linux distros will boot in efi on my wife's asus x501a. I suspect it is related to the ami aptio efi/bios implementation.
