I have managed to somehow screw up the boot.ini or what used to be called the boot file. When I boot it says: Reboot and select proper boot device. The bios won't let me move the boot drive up to the top of the boot settings. I have a Gigabyte GA-Z77-D3H Motherboard. The Bios has QFlash and can be updated. I don't think I have upgraded it because there was a warning not to do it if the computer worked properly. But now I have the boot problem where it picks the wrong drive to boot to. Please help. Thanks much.
