First off I have an emachine 3626 with 1gb memmory I just put in a new GeFORCE6100SM-M motherboard and an athlon 64 processor in it. I installed vista home and it installed on d drive so I erased the harddrive to start over. This time I installed windows 7 and put it on c drive where it should be, My problem is that when it starts it keeps asking whether I want to load windows vista or windows 7 and there is no vista on it. I'm kinda new at this so please any help would be greatly appreciated.
