I do not know who started the page and wrote most of it, but i merged http://grub.fsij.org/TestingOnEFI with http://grub.fsij.org/TestingOnMacbook (since the latter had more info, but the page itself is appplicable to both Apple and non-Apple systems). Most of the troubleshooting part was written by http://ubuntuforums.org/member.php?u=1121774 (nickname metatech). He is active in http://ubuntuforums.org/forumdisplay.php?f=328 sub-forum. You can try these instructions http://www.rodsbooks.com/ubuntu-efi/index.html written by the author of GPT fdisk (aka gdisk). If loadbios does not work, you can try fakebios, although i cant help you there since i have not used that option and i do not own a mac (i did my testing in a proper UEFI 2.3 x86_64 firmware - non Apple system). > http://bugzilla.redhat.com/show_bug.cgi?id=691609 > Basically this problem blocks Live CD's from natively EFI booting a large > class of EFI supporting hardware.
