Wp Wordpress

hi i got a problem I make a bt stick like in the video tut. I use the 5th menu option to edit the system and so on. But wehen i use the default option to boot then no change is ther. Is ther a way to use the changed backtrack but all aditional changes get lost until i boot the 5th option in grub to add more changes?

I need a mode were i can do changes and one were i use a changed system but changes in this mode should be forget after shutdown.
