Looks like OP's error is trying to upgrade with a non Windows 8.1 key.
Upgrade Install to Windows 8 or Windows 8.1
ok recently installed windows 8, now im trying to install windows 8.1 but it doesn't take me to a place to type in the product key, it just gos straight to saying that the key cannot be validated, any ideas??
Windows 8.1 Core 334NH-RXG76-64THK-C7CKG-D3VPT
Windows 8.1 Pro XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB
Install with the correct key for the version you have a legal key for, once your installed activate with your KEY these keys will only allow you to install they will not activate. This is how I Clean installed win 8.1Pro from a Win 7 HP OEM, I had bought the key for $14.95 Win 8 pro in July before win 8 was released. I didn't install until 8.1 was released.
it says that windows failed to validate the product key, when I havnt even put the product key in yet is what im saying
Your computer started out as a win7 hp? so you don't have an embedded product key. I can't understand where your 8.1 install is picking up a Key with out you inputting one?
I didn't try the upgrade path as I know from experience that clean installing it the best way to go, less issues and windows gets a fresh start
