I've been trying to do a Factory Reset on this Asus X54C laptop and I can't get it to go back to Windows 7, which it came with. I think there is a recovery partition on the drive still, which I'm accessing via F9 at boot, but to complicate matters further, everything there is in Spanish. Doing my best to translate the options there, the best I've been able to do is a fresh install of Windows 10.
I tried downloading the Windows 7 ISO from Microsoft with the machine's product key but Microsoft isn't accepting an OEM product key.
I'm looking for some legal way to get this machine back on Windows 7 without having to buy a new copy.
