1, 2 and 3 is what I have done. I haven't ventured into the realms of 4. All the linuxes I played around with were fine with ext2/3. Also, these are experiments from 4 years ago, so you might need to test it once today. 1 is simple. I used GParted, you might want to use fdisk. Whatever floats your boat. 2 - Loop mount the iso and copy all files into the partition created above. If that ISO is LILO/GrUB compatible, things are damn easy. If it's ISOLinux, you'll need to take a little more effort in the next step. 3 - My experiments were mostly with GrUB 1.x. The high level steps remain the same, the actual changes differ for 2.x. Install grub on the MBR for the thumb drive. For 1.x, I manually edited the grub.cfg and used the appropriate grub commands. If it was ISOLinux, I had to chainload here, otherwise directly provide the vmlinuz and initrd paths to the right devices. For 2.x, the configuration file is a lot more complicated, but the bare basic process is similar. I tried doing this a few months ago, but it was all trial and error. So, I can't help you right now with it. Read the instructions for smaller distros like Slax, DSL and Puppy to get an idea of the commands and the process. Another tip: Plug the thumb drive to your box, boot up to the grub shell, and probe all the different devices and partitions correctly on it. Note it down (on a pen and paper), and then boot to your normal Linux. Then, go and edit the grub cfg files. Also, remember that the device numbers will differ, depending on whether the grub is from your internal disk, or your thumb drive. So, set the root correctly. I had to do a lot of trial and error for this. HTH. Ninad S.
