I have a brand new pc build with a MSI a78m e-35d motherboard I have plugged everything in correctly and the bios is running fine, I have set the boot device as my disc drive. I put in my burnt disc copy of windows 7 and it doesn't boot, ive tried everything and it still doesn't boot, is this because my motherboard doesn't work with burnt copies? Im in desperate need of advice because I don't know whether it is my motherboard or if it is the disc, thanks
