You may have to wipe it from the usb key … I’ve been trying to get more information on this forum on how to do that but it doesn’t seem like there are any active users.
I don’t think that any of these copies of windows (from ezpad and similair providers) are legit because they would be way more expensive if properly licensed … also the normal windows recovery would work out of the box if that was case as well … thinking of just returning mine.
