How to install more than one distribution on a single external USB drive


Well, with this forums help, I finally installed Ubuntu on my external USB hard drive so that it will only boot if it is attached. Thank you!

Being the glutton for punishment that I am, I would now like to install more than just Ubuntu on this drive. I would like to have a choice of which distribution to use when I attach the drive.

Is this possible and, if so, how do I do it?

It would be just like using a normal HDD. Partition and install as usual (to the USB drive).

1. Install but don't choose to install the bootloader. On various installers this will be in the advanced section/tab/button, or it might be a seperate installer all together. Just look for key words GRUB, LILO (only for a few), bootloader, advanced options, extra options. Do NOT install the bootloader.
2. When you reboot your computer after installing the Linux, reboot into Ubuntu (or the distro you installed GRUB too) and run:
sudo update-grub
. If your new system installed correctly, GRUB will find it and make an entry on your bootloader automagically.

If you do that you are not at risk and therefore cannot be punished (:
