You can get your Install ISO here, most likely
Win 7 Home Premium 64 bit installed UEFI
Be sure to download all your hardware drivers from
Asus Support Downloads, Chipset, IRST, IME, ATK WIFI, LAN Audio,Video have these ready to install once Windows is installed. I usually turn off windows update until you have at least the Chipset IRST IME drivers installed I find it easier to install the latest drivers before windows update then as you allow windows update to run hide any hardware drivers they throw at you.
