Hi, for some reason my computer will not boot. it gets so far then says that wimdows/system32/system is missing. try R with cd rom - or something like that. I tried reinstalling and repairing the computer with the original cd but it gets so far and stalls. when i press R to repair it asks me to press a number, i press 1, then it wont do anything more. It just stalls. when i try reinstalling xp, it asks me to press F8 if i agree to the terms then it says its looking for previous Operating systems then it stays like that and wont go any further than that action. What must I do?? can someone help me?
