UNetbootin (Universal Netboot Installer) – allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. It runs on Windows, Linux, and Mac OS X. 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

• It can also load floppy/hard disk images, or kernel/initrds, or (some) ISO (CD image) files, for installing other distributions.
• The current version has built-in support for automatically downloading and loading the following distributions, though installing other distributions is also supported:
