You got extremely lucky. @Bios Bricks more MB's than it works on with these modded Bios files. You should always flash from DOS when possible, FLASHSPI (which is included with almost every Gigabyte Bios Download) has proven to be the safest utility to Flash these with. Thanks for the feedback though.
Thanks for letting me know. I have no FDD or USB flash disks atm, and I wanted some quick fix. If only I had known btw, i re-tested the bios. Flashed with the original F5 and windows wasn't genuine. Reflashed with the one you provided - genuine! Once again, thank you.
