Multiple bootable distros on one portable hdd?
 

Hey,
I want to be able to use multiple linux distros from one portable hdd (not all at once). But they're live distros. Just download, burn onto CD and boot from CD.

I want to be able to use these from my portable HDD but how can I do that?

the main 3 i want to use are PLAC, HELIX and knoppix-std.

Is there a program that does something similar to daemon tools but but bootable?

Hope I've been clear enough with my question.

Well, you can install live-cd on hard disk, but there is hell of work needed to cut all of live-cd startup scripts and configure the normal booting. Why didn't you want to use regular distros to avoid this headache?
