dont know if your bios has an flash utility. i know asus has, and i've flashed with it before and it was ezflash. Thought Asrock might too since they operate uefi.
My bios has instant flash?
you havent been very clear to what you're answering too which is confusing.
I suggest rereading how to flash you're bios. Seems to me you tried flashing your bios through windows for god whatever reason and it screwed up. Now, the only way to restore your bios's firmware is to go through these steps mentioned above.
