Changing the boot order to DVD drive should work if you have an original disk! You should get prompted to by post to press a key to start from DVD if the boot order is correct.
Are you saving BIOS settings after changing the boot order?
Yea, I've been saving the settings.
I think the problem is that I'm not using an actual windows 7 disk. I have an original, working key, but my friend had to burn me a copy of windows 7.
Tell me something. I have a computer running windows xp right now. If I put the CD into that computer while windows is running, would you expect that an install screen would come up? Because right now, the only thing that comes up is a folder showing me the contents of the CD. Does this mean my friend burned it as a data CD instead of an image?
