Cannot Boot From Windows 8x64 Boot Disc

I have Windows 8 x64 preinstalled on my Toshiba Laptop. I created a startup disk (DVD) but i cannot boot from the DVD/CD Drive. I set my BIOS to boot from my DVD Drive but i think the problem may be my autoplay settings from DVD Drive. I just don't know how to set them up. the Disk is fine it is not scratched or anything. I don't know how to set up my media devices especially optical so that i can boot from the DVD Drive! Can you help me? Thank You

1) Reset the UEFI/BIOS firmware setting back.

2) On boot up press the F12 key for the One Time Boot Menu.

3) Boot the DVD in UEFI mode.
