Multiple distros on USB

[admrt]

Hi everyone,

I'm trying to setup an USB flash memory that has several bootable Linux distributions on it. One of them will be BackTrack 4. There was no problem before BT4 used casper. But I have other distributions that use casper too. For example, I have BackTrack 4 files on the /bt4 directory on the USB, and Ubuntu 9.04 files on the /ubuntu directory on the same USB.

The only thing I have found looking up hundreds of pages is to use the kernel parameter live-media-path to indicate a directory to the files different from /casper, where files are searched for by default. But it doesn't work, or I'm doing something wrong. Has anyone been able to achieve this?

Thanks in advance

You could probably achieve this easily by splitting the USB drive into seperate partitions and treating it as an internal drive.

Titan is right. Load each distro on a separate partition. You can make these partitions with cfdisk, fdisk, or gparted. Then, when you install grub, be sure to (manually) combine each /boot/grub/menu.lst file into one so you can boot to either distro.

I would like to do the same thing. I do not want to use multiple partitions if I don't have to because I am using syslinux in FAT32 to easily create and manage the multiboot usb. I had a drive with BT3 and Mint working but I want to reorganize the file structure. The kernel boots but then can't find the BT3 directory because I moved it. A flag to specify its location would be great!

I'm working on building a similar multiboot device with the following tools:

Backtrack4
DamnSmallLinux
Mint
Ultimate Boot CD
Derik's Boot & Nuke
BartPE winXP
PartedMagic
NTPasswd
OphCrack
Untangled

As well as additional files / utilities:
Drivers
Installers
Templates
Scripts

In order to keep the drive somewhat in order the folderstructure for bootable images is:

Root (w/ syslinux, syslinux.cfg etc)
\images\[toolname]


I am using syslinux as well to manage as with this many different tools a fixed partition scheme would be difficult and an unnecessary waste of time for managing. The first partition on removable drives is the only one recognized by windows boxes without making a few changes. Leaving everything in the root makes things a mess to manage and leaves things like
\boot
\casper
\data
commonly used and conflicting.
