Asus P4P800 E Deluxe...

I just replaced my motherboard with an Asus P4P800-E Deluxe and i want to reinstall windows for a fresh start but i can't get it to boot from the cd drive. I entered the bios and changed the boot order to boot from the cd drive 1st but it still just starts into windows. Is there something i'm missing here? Everything else is working so far, just can't get it to boot from the cd..... Any help would be appreciated. Thanks

Are you using a raid setup?

No, i'm not using Raid. I figured it out, my old system was a compaq so to boot to the cd i had to press F1........ Thanks for the reply matty.

Pressing the f8 key on post brings up the boot options on p4p800e and p4p800se.
