fist of all you need to know how to install backtrack on usb with persistant chnages
meaning your changes are persistant lol
download : http://www.linuxliveusb.com/
and install it with the persistant mode box ticked if you have problmes just pm me
unetbootin requires to install a larger casper-rw but we wont get into that now
