So I have this old emachines computer that has system32 errors and won't boot.. So I put in the windows xp install cd in there and the booting process just continues as if the cd isn't even in there.. I put the windows xp cd in my primary computer and it recognized it so it's not the cd. I put the windows 7 install cd in the emachines computer and it recognized it so that means the cd drive works. I am totally stumped as to why the computer won't boot the disc. Thanks for help in advance! Henry
