Scott wants to know if he can take the hard drive out of an old computer and then put it into a new one. Leo says yes, but he should only use it as a data drive. He could probably put it in an external USB enclosure so he can plug it in when he needs to. He could install it as a secondary hard drive as well. If he wants to use software from that hard drive, that's a lot more problematic due to registry issues. He may be able to dual boot from the older driver, but the device drivers won't work. So he'll have to work around that and use a boot manager.
