i just made a seperate partition on a windows 7 laptop for windows xp os. i put the cd in, installed it there. now it wont let me go back to windows 7. wtf? i did everything right but it still didnt work. idk if its worth noting but my packard bell c:\ changed to e:\ in windows xp, and c:\ was called system reserved. so now i can only access windows xp. and i cant find any drivers either. i tried changing my sata mode back to ahci mode and it still wouldent boot to win 7. it just crashed. but it should have a list of os's windows 7 and windows xp but it dont.
