view story

http://askubuntu.com – This is a new computer that can only boot in UEFI mode. ( or at least I do not know how to switch to normal BIOS mode). I am not able to install ubuntu 12.04.1 or ubuntu 12.10 using the livecd. The live CD does not boot properly. I get error message with subsequent kernel panic. It came with windows 7 preinstalled. bcdedit indicated that windows in UEFI mode. The problem is not solved even when I disconnect the windows disk. (HowTos)
