I installed windows 7 from a .ISO file I downloaded. After the 30 days I attempted to activate it with DAZ activator without reading everything about it. I believe it was 2.something. When I tried to reboot it would not boot. This computer will not boot from a CD and the only thing i have gotten it to boot from was a Hirens boot USB drive. The problem is I don't know what to use from here to fix it or if I can fix this problem from Hirens boot CD. Any help would be greatly appreciated. Windows starts to load then I receive a blue screen of death saying Unmountable_Boot_Volume. I also get errors from within HBCD when attempting to look at the drive. The HDD was fine before this though.
