Thats not your productkey but Product ID only. We need to know something, not just what build and version. Have you tried anything ? what loader did you use ? slic 2.1 in bios ? etc..
I tried with many loader and nothing, i tried insert a product key wich a find ond this forum for hp an nothing, slic 2.1 in bios i did not tried
Downloaded windows 7 from here ? If not you might have pre-activated crap, if so read sticky and that'll help you.
