error on booting

[zao400]

hey people,

ok here is the deal, I am creating a mult-boot dvd from this website http://flyakite.msfnhosting.com/. I did the XP pro part, and Windows 98SE part, and did the codding for the menu in cd shell. Well I decided to go ahead and complie cd cd image with cdimage. Then burn it onto a dvd using nero 7. Now here is the part that is troubling me, when I reboot the system with the boot cd in. It started to boot up and then displays an error message. It says can not boot from CD/DVD, please press a key to reboot. and at the bottom on the screen it displays this. 80800AF9.

So can anyone help me on how to fix this.

Thanks
