Install BackTrack 5 Revolution 2 on external hard drive

[ Thanks to finid for this link. ]

While you can install it on any computer, I think the
best practice is to install it on an external, USB hard drive.
Doing that, gives you a pentest distribution on the go plus all the
extra storage you might need.

You may also opt to install it on a USB stick (a flash drive),
but if you choose to go that route, be sure to have one with a
capacity of more than 18 GB. Why? A default installation of
BackTrack 5 R2 takes up just a little bit more than 18 GB of disk
space. It is huge.
