UNetbootin creates bootable Live USB drives for Ubuntu and other Linux distributions without burning a CD. It can download supported distributions or use a Linux ISO stored on the computer, and lists a USB drive or hard disk as an installation target. Its built-in downloads include Ubuntu, Debian, Fedora, Arch Linux, Linux Mint, and FreeBSD, among other distributions. It can also load system utilities such as Parted Magic, SystemRescueCD, and rescue disks. The site says most Linux ISO files should work, though some need extra boot options or modifications, 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 options 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 a targetdrive option if the destination is not detected. UNetbootin is free, accepts donations, and identifies its license as GNU GPL Version 2 or above.
