UNetbootin is now available in several languages.
It works by extracting an ISO file to the USB drive and creates the proper syslinux config making your distro bootable. Make sure your BIOS settings are configured to try booting from a USB drive when present.
From there, you can now run your Linux distrubition and boot from it. Usage is simple and with Windows, you can grab an ISO, select a target drive and once done, reboot. It loads distros from ISO images you've downloaded from a particular site and those that you've created yourself. The program can run on Windows, Linux and Mac OS X. It can turn a USB drive with sufficient space. UNetbootin is a utility allowing you to create a live, bootable Linux Distro such as Ubuntu, Redhat, Fedora, Debian, etc without having to waste a CD. Excellent software for users of Linux or BSD for creating bootable media for the most popular Linux distros.
