In my earlier post I had posted an article on "Bootable Windows 7 Flashdrive". This time I will give an idea on how to make a persistent(i.e. all your data including desktop settings will remain intact) Linux flash drive. Booting from Linux is great but its better if you can carry your whole Operating System with you. This insures that you are always secure from malicious objects and also add that little personal touch wherever you go.
