So I'm switching motherboards, and my previous board had an OEM version of windows that wont transfer over the license. I can get a free product key for Windows 10 Education through my university, my question is how would i go about reinstalling windows on my boot drive? Would i have to clear everything off of the drive then reinstall windows, or when i reinstall windows will all the old files get automatically deleted or replaced.I'm referring to the old OS files because im moving over from windows pro to education.
