I swapped the hard drive out of my mothers computer to my sisters, and my sisters to my mothers, both get to the option to load windows, but neither will. my sisters comp restarts, and my moms comp freezes after i tell it to run normal or in safe mode. i tried the jumpers the way they were, then i tried swapping the jumper on my moms hard drive to the way my sisters was. and it had the same problem. any ideas whats wrong? both were masters. and i loaded them both as masters.
