UNetbootin
What it is
UNetbootin creates bootable Live USB drives for Ubuntu and other Linux distributions, allowing users to prepare an installation without burning a CD. It can download a supported distribution or use a Linux ISO already on the computer, with a USB drive or hard disk as the target. Built-in download support includes Ubuntu, Debian, Fedora, Arch Linux, Linux Mint and FreeBSD, among other listed distributions. It can also load system utilities such as Parted Magic, SystemRescueCD and rescue disks. The site says most Linux ISO files should work, although some need extra boot options or changes and some cannot boot from USB as-is. Non-Linux operating system ISOs are not expected to work because they use a different boot mechanism. Linux download choices include an Ubuntu PPA, 32-bit and 64-bit binaries, packages for several distributions and source code. The FAQ points to command-line options, including targetdrive for cases where a target drive is not detected. UNetbootin is free, donations are accepted, and its source is available on GitHub under GNU GPL Version 2 or above.
