hi, following this link : http://www.pendrivelinux.com/creatin...e-usb-from-cd/
i created a usb stick ubuntu 12.04 .
it says in the article that i could have a persistent live usb persistent ubuntu OS.
after i done it, it still gives me a choice between installing the OS ubuntu 12.04 or to try it.
i was under the impression that i could use this has a regular portable OS.
should i install it now or i just use the try it option and the difference between a live cd is that any change i made will be registered, meaning i do not need to choose the installed option ?
