I don't exactly know what you try to accomplish, but you should first understand how booting from a CD works: The BIOS of your computer acts as if it is booting from a floppy. While a boot floppy is restricted to 1.4 MB (under Linux I usually format them to 1.7 MB), the limit for a floppy filesystem image is 3.4 MB (note: Especially older BIOSes will not boot from big floppy images!). So what you need first is a bootable floppy image. A floppy image is the complete content *including* the filesystem metadata ripped into a file (just like an ISO image is a complete CD filesystem in a file). Once you have created an image of a bootable floppy (with dd or by using one of the bootfloppy images on the first Red Hat Linux CD), you may need to change something inside, so it will boot the way you want. You can do so by mounting the image (as said, it's a complete filesystem!) using the -o loop option of mount (man mount for details). There are several hhowtos about booting, search on http://www.tldp.org/ for "boot". The most important is: http://www.tldp.org/HOWTO/Bootdisk-HOWTO/ After you have your boot floppy image, you create a bootable ISO image. For this you use the -b /path/to/bootimage.img option of mkisofs. The boot image must be included in the files you include in your CD, of course. Then you burn the ISO image onto a CD with cdrecord. If you are using a graphical tool like X-CDroast or a burning software on another OS like Windows or MacOS, look in the menu of that program. It should offer to create a bootable CD. When you choose this option, it will ask you for the boot floppy image you want to use to boot the CD.
