One of my gigabyte utilities said there was a bios update and I did it and the computer starts and the GIGABYTE Ultra Duriable logo comes up and then it says " An operating system wasn't found. Try disconnecting any drives that don't contain an operating system" I didn't disconnect anything so why can't it find my os? How can i fix it?
