I'm new to Linux and have a possible stupid question regarding booting multiple liveCD ISOs from external HDD. I found this link in the forum (http://ubuntuforums.org/showthread.php?t=1288604) and have a few questions.
My first question is, can this be applied to my USB External HDD? and can i use a more up to date Ubuntu live CD? Will i need to format my HDD to EXT4 before hand?
Thanks for any help.
