New computer boot problem

I just finished building my computer and I'm getting an error.

I'm running:
AMD 3500+ Venice
EVGA 6800GT PCIE
OCZ DDR500 VX 2x512MB
DFI UT LP Ultra-D
Seagate SATA 80GB HDD
Thermaltake Shark Case

Everything is running nice, nothing really heating up. The only problems I've been having is with my case. It appears TT seems to round off their measurements to the nearest inch, which makes fitting the mobo tray up against the back panel an ass ache.

I turned on the computer for the first time and all the bells and wistles were sounding correctly. It went through the initial BIOS settings for confirmation and everything was perfect. It then started with a:

DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER

I'm still not sure what it could be. Anyone able to point out my ignorance?

My hard drive is showing up as 80GB which is correct.

Check the boot order in BIOS - it should have CD ROM before hard disk.

failing that, take hte error message at face value and make sure the cables to the CD are installed correctly and the CD is recognized in BIOS.
