Constantin mentioned earlier and I shared this feedback with another user. They suggested using the Windows USB installer for a "Repair" — sometimes cloning isn't as straightforward or dependable as it should be. They reported around a 40/60 success rate, meaning 40% of attempts succeed and 60% fail. If it works, it saves a lot of trouble, but if not... The cloning idea is promising, though the error rates need improvement, possibly due to Microsoft's efforts to curb piracy.
