If your system doesn't want to boot directly from optical media, that
ultimately comes down to your BIOS and its settings, which I'd recommend
checking. That said, GRUB should be able to chain into a CD-ROM.
http://www.lrz.de/~bernhard/grub-chain-cd.html indicates how you can do
so with legacy GRUB (0.9x); I see no analogous instructions for GRUB 2,
but it looks like it should work to load the biosdisk and iso9660
modules and then boot the CD's kernel and initial RAM disk.
