LOL first you're in xbox hardmods. Second you should be able to access your bios and make sure your boot priority is set to boot from the cd drive before the hard drive. To access the bios watch when the computer starts up, try hitting the esc key a couple times, and you should see a message on the bottom like press f1 for setup. It's pretty simple. If you have a bios lock password and you forgot what it was just take the comptuer apart and take out the little button-cell battery on the motherboard. I'm sure when your topic gets moved you'll get more help if you need it.
