I bought a new motherboard, so I had to format it and when I wanted to boot the CD (Windows 7 Installation) when I restart, it won't show anything even if I click F12 and boot CDROM. My motherboard is Gigabyte G41M-Combo
I think you are asking about Bootable CD becuase you can operate this disc before to ctart the windows and this si only windows XP and other bootable disc so you shouild buy a windows cd for operate this disc in startup..
