dual/triple boot USB drive
OK, so I have a few questions regarding the set up of a bootable USB drive.
I realize I can set up a USB drive to boot up an OS. SO, is it possible to have the USB drive partitioned correctly to boot up an OS, and within the USB drive have it partitioned to be able to open once its in the OS to open certain software/programs/utilities within the same USB drive?
Lets say I install OS ubuntu 11.04 as a Live USB, then once I have booted up in ubuntu on the computer be able to open up folders within the USB drive and operate them or install them in the OS. I know just setting up the OS within a HDD would be much simpler as going in and just setting up the programs/utilities with the HDD but I am trying to set this up to where I can go to any computer and just run a Live OS then use the tools within it accordingly.
If this is possible (which I presume) what programs would I use to set up/partition the USB drive to do this with? Also, which program would be the easiest to do this with?
Better yet, could I apply more than one OS on this USB drive and have maybe a boot menu like GRUB or something similar to give me a choice of which when the USB boots of having an option of which OS I want to boot up, then use the programs accordingly?
Another question, would be how much space or size of the USB would you recommend? I am thinking about ordering a 8G USB drive, but maybe a 16G would be better for what I'm trying to do here. :confused: Opinion, please.
On top of this, could I still use the USB drive to just store files from my regular OS I use on a daily basis, that would of which I could add more programs/utilities to so then I could open them up with my USB Live OS?
My OS now is Ubuntu 11.04 Natty, which I will be using to set this bootable USB drive up with to use on any computer.
Any information would be helpful and the more the better, details/tutorial links please :D
EDIT: What type of USB drive should I get, or can just any of them be set up to do this?
