This is my first post on these forums, so please bear with me! I am not very technology capable, but I try to be able to follow directions and figure stuff out. Here is the scenario. I have an HP laptop that is not doing well. The hard drive was the problem, I believe. I switched the hard drive with a similar one (same manufacturer and size). How do I get the copy of Windows 7 that was on the old hard drive onto the new one? To make matters worse, the new hard drive was formerly used in a Dell laptop (which is no longer with us, may it rest in peace). It has a copy of Windows 7 on it already. Is there a way that I can erase that copy of Windows 7 and put the copy of Windows 7 that was originally on the HP onto it? The Dell hard drive had Home Premium on it, the HP drive has Professional on it, if that is any help. Thanks for any help!
