I have an olded computer. When it turns on and shortly after everything turns off. The old hard drive has some things on it I would like to save. I have another computer (both have xp), can I pull the hard drive off the old one and put it in the new one? Both hard drives have xp so if I put it the other one in will it dual boot acceptable or will I have to temporarily disconnect the other drive to get access tp my older drive?
