Ubuntu: How to create a bootable USB drive from ISO file

I no longer trust CDs, it's time we phase out CDs and put it in the category we created for floppies.

So, if you have a Ubuntu iso file (if not, get it from here) how do you get it installed using your flash drive?

Step 1: Get UNetBootin

• add the following lines in /etc/apt/sources.list

  http://ppa.launchpad.net/gezakovacs/ubuntu hardy main
  deb-src http://ppa.launchpad.net/gezakovacs/ubuntu hardy main

• sudo apt-get update
• sudo apt-get install unetbootin
• if you run into dependency issues, run 'sudo apt-get -f install'

• if you are installing from windows/mac, download the corresponding version of unetbootin from here.

Step 2: Launch UNetBootin

• click on the Diskimage radio button, and add path to the iso file
• select Type as 'USB Drive' from the drop down menu, and add the Drive letter in the next drop down.
• for linux users, you have to check the 'Show all drives' checkbox and select the appropriate one (do a 'mount -l' to confirm)
• it will now extract the files to the USB and make necessary configurations to make it bootable
• select 'reboot now' option to install on the same machine, or unplug the USB and boot with it on another machine
