I've just finished building my pc and I'm a bit co friars on how to install windows. When the splash screen comes i press f11 to get to boot order and it says "no boot device detected" If I then select configuration it takes me to the same bios menu that I get if i dont press f11 in the beginning. Ive plugge in my optical drive Into the sata 3 port on the mobo. It's an LG CH12 combo drie. Help?
