Success: Multiple live distros in a single external HDD with GRUB2
So, here I am, with my brand new external USB HDD and wonderign what can I do with it. Of curse!! an "all terrain" rescue hard drive with all the live distros I need!!
This is a HOWTO create a rescue HDD containing multiple (or single... but that's not so funny) live distros with the extra feature of implementing GRUB2.
- You have a formatted and sized partition on your HDD
- Your host system has GRUB2 (1)
Part I - Preparing the files
Here I assume you are on your HDD-mounting-point folder
1.- create a file for the boot folder in your HDD (one for each OS)
Part II - Installing and configuring GRUB2
For this part I assume you are at /etc/grub.d/
4.- install grub in the HDD
5.- create a xx_os script for each OS IN THE HOST SYSTEM
* take this data from the menu.lst/isolinux.cfg or equivalent from the boot/ folder of each OS
* REMEMBER to ADD /os-boot/ at the start of each line. This is to give GRUB the right path. More details in step 4 of the first source (below)
6.- generate the grub.cfg
-first, set permissions for 10_linux script to 644 in order to avoid the inclusion of the host system
remember to restore the permissions to 755 for 10_linux script.
I also recomend to delete, change location or change permissions (to 644) for every new script you made for this.

(1) This was indeed the root of all my problems. I have GRUB2, and all the howto's I found implemented GRUB Legacy.
