Norton Ghost 14, System Recovery Point on DVD, PC dosn't boot from it.

I have tried everything,

 

I have even set the bios to only boot from cd in all boot options,

 

when I boot, it says "boot from cd/dvd"

 

I click "enter" and it then boots from the system hard drive anyway?

 

CD drive is Plextor PX-800A

 

Motherboard is Gigabyte P55-US3L

 

Windows XP Professional Service Pack 3

 

Any help would be greatly appreciated.
