I installed this ~a month ago with the modded bios (Asus) for my ASRock 939Dual and it activated properly - Genuine Windows. A couple days ago my drive order was changed after I added my backup installation to the boot menu and it apparently became unactivated, along with my backup installation. I went through the activation procedure with my backup system and it reactivated fine but my main system will not reactivate. I've went through this a few times to no avail: I've removed the keys with slmgr -cpky and slmgr -upk too but it made no difference. Oddly, when I check with MGADiag, it sez that my system is Genuine but I still have the 15 days for activation in System properties. Anyone have an idea what's wrong?
