how to make USB install NOT persistent

[nullman]

Hi im new here and i couldnt find this on the forums

i successfully installed bt4 on a 8gb sundisk cruzer blade and it works perfectly
the problem is that i want to be able to load it without saving changes so if i mess something up i could just reboot... but so i would still be able to log with persistence when required to update programs and install stuff

i use the default grub menu that came with the install and i tried to insert the "nonpersistent" flag in there but it doesnt seem to be working :\

i have been googling my ass off im sure im missing something completely obvious but i just cant find it



thanks to any one who can help me edumicate myself

I believe you are asking if you can log into persistence, run your updates or install nessus, then be able to access those update programs/nessus in a non-persistence mode so you can reverse anything that may mess up by rebooting.
That would be excellent. However, persistence runs from the separate partition you made on your stick whereas non-persistence does not. So when you run it in non-persistence, it doesn't tap into the persistent partition you created thus you wont be able to use nessus or updated programs.

perhaps there is a way to get grub to make the partition not persistant or hperhaps not load it at all?
