Okay so I'm trying to install windows xp back on my mac using boot camp. I start the installation, pick the correct partition and let it start to install. Well after the first menu is done, it says it needs to restart. Well it does, then it comes up and says something about booting from a cd. So pretty much, it starts the installation completely over. Why is it doing this and what can I do to fix it? I've had windows xp installed on my mac before using bootcamp..
