OK, so i downloaded the Ubuntu 7.04 image and burned it to a disk. I play it from windows and everything goes great. Then I set my boot sequence as CD-ROM first, reboot, and it pops up with the Ubuntu menu. I felt like I was flying. Then I try to use the arrow keys to move up and down to choose, and it wont let me. So I press enter to start or install it, and it wont let me. So I wait until the time runs out and then it says something to the effect of "BIOS error". So I reboot and put my HDD as first boot, then I am here talking to you in XP Home. Help!
