Instalando o BackTrack no USB

This method of getting a live install to a USB drive is the simplest available using Unetbootin. Note that we will format the USB drive and erase its contents.

1.     Plug in your USB Drive (Minimum USB Drive capacity 2 GB)

2.     Format the USB drive to FAT32

3.     Download Unetbootin from http://unetbootin.sourceforge.net/

4.     Start Unetbootin and select diskimage (use the backtrack-final ISO)

5.     Select your USB drive and click “OK” for creating a bootable BackTrack USB drive

6.     Log into BackTrack with the default username and password root / toor.

Esse outro método é um pouco diferente, mas funciona. Assista o video aqui.
