Booting Linux from a USB Memory Stick
Linux on a Stick
Everyone knows you can boot Linux from a live CD,but have you thought about putting Linux on a compact and highly portable USB memory stick?
Abootable “live” CD like Knoppix  or Kanotix  gives the user a fully portable operating environment. You can carry your system with you and boot it from anywhere. Your tools, your files, and your workspace will follow you wherever you go – even to another PC with a different operating system. Live CDs are also used by system administrators for troubleshooting computers that won’t boot normally. What could be more portable than a live Linux CD? What about a live Linux USB memory stick? A tiny USB memory stick is even more portable, and often more durable, than a CD, and writing to USB memory is typically smoother and faster than the business of “burning” data to a CD.
