I was just wondering, is there a way to burn the image to a USB Key instead of a CD? I want to use my USBKey to boot some utilities. It is so much easier than carrying around a cd. Please let me know. Thanks.
Yes there is a way, kind of. Some Linux distributions (that's what they are called) have support to boot from a USB key disk. How is this useful to you? Well, there are programs called boot loaders that are in charge of "booting" the operating system: Windows, Linux, Solaris, BSD, etc. There are ways to install such boot loaders to boot multiple operating systems from a USB key disk.
Here are some links to USB bootable Linux Distros:
