UNetbootin allows you to create bootable Live USB drives for Ubuntu and other Linux distributions without burning a CD.

You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file.

Features:

• UNetbootin can create a bootable Live USB drive.
• It loads distributions either by downloading a ISO (CD image) files for you, or by using an ISO file you've already downloaded.
