I had to reformat a laptop that had Windows 8.1 Pro (laptop has a sticker Windows 8), I did not backup the tokens (didn't know about that). I used the iso for multiple editions, but during install I was not asked to select version, and it installed 8 standard. And in all cases, Windows is not activated. I got the key from the bios, but when I enter it in the slui 3 it says not usable. Tried using KMSPico, it also says bios key found, skipping... What other solutions are there? can I force the installation of pro and use the bios key?
