So I'm trying to reinstall windows, but I'm using an old backup copy of my windows xp cd, so I'm not sure if it'll still work... I don't suppose I can reinstall it without a CD can I? I tried to run boot camp, and I don't think I can install a 3rd partition as a test for the CD, and it looked like the only way to get the reinstall windows is to remove my windows partition and then install a new one. If I kill my windows partition, is there any way to get it back if my CD fails?
