In my last post I mentioned UNetbootin – a great tool for Windows and Linux that allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions (VMware ESXi) without burning a CD. Here's another such tool, but with few extra features added.
Universal USB Installer is a Live Linux USB Creator that allows you to choose from a selection of Linux Distributions to put on your USB Flash Drive. The Universal USB Installer is easy to use. Simply choose a Live Linux Distribution, the ISO file, your Flash Drive and, Click Install. Other features include; Persistence (if available), and the ability to format the flash drive (recommended) to ensure a clean install. Upon completion, you should have a ready to run bootable USB Flash Drive with your select Linux version installed.
I particularly like the "Persistence" feature to create Linux LiveUSB that allows me to save data changes back to the USB storage device instead of leaving the information in system RAM. This data can then be recovered and used again on subsequent boots, even when booting from different machines. Now I always have a bootable Linux USB in my pocket.
