I have a 2TB WD Black HD with a copy of windows 10 which is upgraded from Windows 7 OEM, i plan on getting a new PC soon which comes with windows 10 Pre-installed, now heres the problem i want to use my 2TB WD harddive on this new PC and im pretty sure i cant use the drive on a new PC with an OEM so does anyone know of a way that i can either use my old HD with the old install or a way to swap the pre-installed windows 10 on the new hardeive to my old drive?
