The cdimage that\'s for download from this site, is really only made to make Microsoft Windows NT/2k/XP bootable CD\'s. If you\'re talking about a different cdimage, I\'m not sure then.
I would recommend looking into Norton Ghost. It can make an entire backup of your whole drive, or just certain partitions. If you make a floppy image that will help restore this image, then you could make your cd bootable by using thta floppy image. Most CD burning programs let you choose a floppy disk or an image of one to use to make the cd bootable.
