two hard drives one computer windows 7 and old windows XP
Would like to take hard drive from my old computer that over heats and is dieing and add it to my new computer with all new parts and faster. Would like to tell it which one to boot to when turning on and be able to go from one system to the other by way of key board without turning everything on and off if possible. If this can be done please give me the complete steps to take and what I may need. Do not want to format and lose programs or data on either hard drive no good then.
