UNetbootin

How to Continue Where You Left Off (Save Changes)

Asked by Ari L

I've recently used UNetbootin to create a live USB of Ubuntu 10.04. Everything works great and I can access Ubuntu perfectly. The only issue I have is that every time I shut down the OS (which is pretty much every time - hence it being on a USB), I lose all my data. Such things lost are items I downloaded from the Ubuntu Software Center (specifically Compiz related stuff), and even things as simple as adding items to the panel at the top. Is there anyway to save any new data to my "hard drive" which in this case is the USB. I would assume that it requires tweaking some sort of setting in some file on my USB if it's possible at all. Thanks in advance!

This happens because you are using a live image, rather than an installed OS. What you need in order to retain changes to the OS is a persistence file.

There are instructions for making your live USB persistent here:
http://unetbootin.sourceforge.net/diskimg/readme.txt

Alternatively, if you use the startup disk creator (System > Administration > Startup Disk Creator) instead of UNetbootin to create your live USB, there's an option to create a persistence file of whatever size you specify.

I upgraded UNetbootin to be able to have drop-down options for 11.04, and to my surprise persistence for Ubuntu is now an option right from the GUI. THANK YOU !!!

Can you help with this problem?
