LiveUSB Install is another nice third party Live Linux Bootable USB Creation tool created by Krasimir S. Stefanov. It can be used to quickly install a Live Linux distribution of your choice on a thumbdrive from ISO, CD/DVD, or torrent download. Other unique features include the ability to customize the syslinux.cfg file, use WinGrub, or write an IMG file to the flash drive.
LiveUSB Install was written in python and will create a Live Linux USB from within Windows or Linux, so it is an optimal choice for those who prefer not to use Windows.
