I have a lenovo laptop that came with Windows 8 x64.
I used ProduKey to extract the license key of my Windows 8 x64.
I downloaded a Windows 8.1 x64 ISO and tried to do a clean install of Windows 8.1 using a USB. It asked me for a key, so I put in the key that was extracted. It said the key was in valid
I also went to this website, Upgrade Windows with only a product key - Microsoft Windows Help, and tried to use the key for both Windows 8 and 8.1, but both of them didn't work.
I booted the USB in legacy mode (NOT UEFI mode)
