if you install norton system

works in windows, there should be an option lets you burn a bootable cd. I myself made one such way.
BTW, you can use nero to burn a dos booable cd, but not a ghost bootable cd.
(a ghost bootable cd with u*****/firewire support, combined with a u***** or firewire external hard drive, makes a perfect system backup solution for home computer, highly recommanded to everybody!)
