UNetbootin Live USB drives under linux or windows

http://unetbootin.sourceforge.net/

Introduction

UNetbootin allows you to create bootable Live USB drives for a variety of Linux distributions from Windows or Linux, without requiring you to burn a CD. You can either let it download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list.

Requirements

• Microsoft Windows 2000/XP/Vista, or Linux. If you are having trouble with the Linux version, try the Windows version, it usually works better.
• A broadband internet connection to download the distribution's .iso file (unless you're using pre-downloaded files)

Features

UNetbootin can create a bootable Live USB drive, or it can make a "frugal install" on your local hard disk if you don't have a USB drive. It can load distributions by automatically downloading their ISO (CD image) files, or by using existing ISO files, floppy/hard disk images, or kernel/initrd files, for installing other distributions.
