... That is terrible advice. You can't transfer over a drive with an operating system already on it. No exceptions.
Not only that, but windows doesn't care about what HARD DRIVE it was installed on. it cares about what hardware was used to activate it. New mobo = new activation.
Two bits of incorrect advice in the same sentence. Please edit the post so others don't believe they can simply take their SSD and put it in a new system.
