I recently installed the ISO for 12.04 LTS on a 4GB USB. I installed and started up Ubuntu perfectly from my USB. Now, I had to restart my computer and when I started it back on (from USB) it was practically a freshly installed Ubuntu, with all of my files gone.
Can someone tell me how to avoid this problem (start up the same way every time so I do not lose files)? Or if there is a possible way to move the ISO to my HDD and then start up from there every time?
