Installing and boot a Linux operating system on a USB stick
So you just downloaded an .ISO image of your favourite Linux distro but don’t have any blanc discs laying around to burn it to. UNetbootin allows you to install your Linux operating system on a USB flash drive and makes the USB bootable.
The utility will either download and install a specific Linux distro for you or you can point it to an .ISO file that you previously downloaded. The utility will install the .ISO file onto a USB stick and make it bootable. The utility is very easy to use, the screenshot pretty much explains itself.
The utility supports many linux distros: Ubuntu, Debian, Linux Mint, OpenSUSE, Arch Linux, Damn Small Linux, Slitaz, Puppy Linux, gNewSense, FreeBSD, NetBSD, Fedora, PCLinuxOS, Sab, Gentoo, MEPIS, Zenwalk, Slax, Dreamlinux, Elive,CentOS, Mandrive, LinuxConsole, Frugalware, etc…
You can visit the UNetbootin website for the download link and additional tutorials. This utility can be installed in Windows, Linux or a Mac.
