I have just built this computer http://pcpartpicker.com/p/NJwL4D
I turned it on and configured BIOS to boot from CD/DVD drive, and inserted my Windows 8.1 OEM DVD. However when I boot up the computer it says please choose a different place to boot from or insert and then reboot. I've tried IDE and AHCI mode, I've tried UEFI and UEFI-Legacy, in UEFI it just goes to the start screen. What am I doing wrong?
