I want to install window 8.1 enterprise (uefi), but I couldn't. The problem is Dvd drive not recognise uefi dvds. I try many dvds of uefi. when I start to install window, it says - can't install, disk drive is of gpt style. I have try every bios setting. this is not the first time I installing uefi window. I have another uefi enabled boot disk (3TB - window 8.1). what can I do now?
