Ok, I want to create a DVD with all four K/X/L/Ubuntu live CDs on it. I'm going to make one with the LTS versions and one with the latest.So first question, is it possible to partition a DVD? If so, how can I do it? Can I install each Live CD on a partition and give me a boot option (with GRUB 2 or other bootloader). Or, can I combine all of this into one .iso file and burn it to the DVD? That way I could distribute it and make it easer for other people to do the same. My goal here is to make it easier to show people Ubuntu. With all of the derivatives in one place, it would be pretty easy. I will probably eventually get a USB to do this, but I don't have spare one. The only one I have is being used for all my Wii hacks.
