Neverluke, shouldn't the OP be able to reconnect the hard drive and just verify that windows is a genuine copy regardless of the version of windows, even if it takes a phone call? Years ago I swapped from AMD to Intel and I didn't have to reinstall everything, but I'm not sure what version of windows I was running then.
Dont think so. When you install windows, it also install drivers that are compatible with your hardware. The problem comes when you want to change that hardware and windows cant boot because it does not have the drivers it needs to handle thath new hard, and cant download it also, because, of course, it cant boot.
Seems like Windows 10 got that resolve, dont know how. As I say, I upgraded from a FX 8320 and a Saberthoot mother to the I7 and the Gaming 7, and I got a very nice surprise when it just worked.
