Hey, I activated 7 using a loader, Windows showed it was activated. However, after restarting it, I was back to trial mode. What may have happened and how can I resolve this? My mainboard is a Biostar Gf7050 M7 V6.x. I'm a bit shy to flash my bios since I don't really want to possibly brick my board. I remember exactly the same thing happening back when I tried activating Windows Vista via a loader.
