	Actually, I'm on the quest, Colin is trying to assist. Thanks for the 

	What I've done so is I've used Unetbootin to get my 1GB FAT32 USB key 
setup as a Ubuntu install device, have ~250MB leftover for saving data 
between boots. I also have is a 60GB external HDD setup to run Ubuntu 
12.04.1. Nice, I can take my Ubuntu desktop with me in my pocket... :) 
So between the 2, I'm doing OK.

	What I would like to be able to do is have the ability to kick off a 
Ubuntu install from the 60GB HDD (eliminate the needs for the 1GB USB 
key). I have a couple of possible options:

1 - use "dd if=/ubuntu.iso of=/dev/sdc1" to write the iso straight to 
the external HDD. Once I verify that works, use gparted to expand the 
partition to the rest of the drive.
2 - Leave a small FAT32 partition at the start, use the rest to have my 
Ubuntu desktop. Then use Unetbootin to install the casper goodness on 
the FAT32.
3 - Anyone else got any ideas?
