Hello. I am trying to recycle a laptop to my nephew and wanted a clean/fresh install. It was originally a win8.1 then upgraded to win10. Ive tried unsucessfully to reinstall windows 10 using a flash drive created with the win10 tool. But I keep getting an
error about corrupt install file. Tried 2 different usb drives and reinstalled the tool multiple times.
Do I have to install 8.1? Can I upgrade it to 10 if i do? I do not want to fumble around and end up invalidating my copy of windows.
