Turning restore partition into a bootable dvd

I can quite understand the gooddell site on the restore partition. All i want to do is pop the dell restore ghost image onto a dvd, and make it bootable so i can restore the os onto the pc when i sell it at some point in the future. I want to install linux and experiment with osx but the dell mbr doesnt like those partitions and fails to boot ontil i reinstall windows or axe the 25meg dell auto boot mbr thingy.

Does anyone have a step by step guide to copying the ghost image to a dvd, and booting from the dvd to restore the os?
