In another thread some one told me that if I buy a new mobo, processor, RAM, video card then I can't use my old hard drive with WinXP on it. Cuz it wouldn't recognize it or something.
Is this true? Do I have to buy a new HD/OS to use the new parts?
do that, then move the data you need from your slave (old) drive to the new (primary) drive... then format your old drive and move back (if you want to)
