fwiw, when I install windows fresh, I will boot off a usb flash drive/installer and choose the Custom install,, delete windows and all the system partitions - somewhere along the line it presents a list of windows versions, in my case its edu, edu N, enterprise, enterprise n, Pro, Pro n, more...
It didn't offer you a choice ?
you might download the insider iso for Enterprise, 'for use on another computer' as its installer doesn't even have an option for regular Home.
Maybe make the installer for pro 'for use on another computer. Or try the Microsoft Store and search Windows, it will offer Windows pro and use the key there. Maybe you'll get lucky. The oem key is for use on a computer that has no embedded key.
