Okay, I have Win7 Ultimate on a machines, and I want to put Ubuntu 12.4 on it instead. I made a boot disc, flipped my boot order to CD first in my BIOS. It gets a little ways in to POST, and says "Booting from CD..."
Then it just starts windows anyway without doing any unbuntu boot stuff at all. But it doesn't boot right to Windows, it boots to a 'Windows has failed to properly load, enter start repair or start windows normally screen.
Anyone have any idea how I can make this work?
