I am building a desktop and everything is working fine except when I turn it on and want to install Windows it just goes to BIOS and there's no other options presented. I burned Win7 to a DVD-R and as far as I can tell the disc is usable, so I don't know what the problem is and I can't find an answer anywhere I look.
