Thanks for the response.

If I use the boot options and copy /KNOPPIX, "asking me for the size of the persistent image" sounds like I am copying the ISO files and not replicating a regular install. Is this correct? I am trying to at least simulate a regular install to sdb7 and use sdb8 as the swap. This way I can keep it updated.

Maybe this will help explain my situation. I can always take three live dvd disks with me (2 live dvds, 1 live cd -- 3 different distributions), or because of ease of use I have an 8gb USB with the same distro ISOs on it. I would like the 3 distros on this high speed USB (30mb/s - 32gb) as regular installations so that I can keep it updated and add certain packages to certain distros, because each one does certain things better than the others. It is the custom ISO image format installs that I am inexperienced with.

I may be trying to do something that is not possible with the given software and setup without serious modification. But if this is workable, could you post the Grub section for the Knoppix boot commands and parameters, and then I should be able to use and edit that since I currently do not have a running multi-boot installation with Knoppix.

Thanks for your help.
