I have installed Ubuntu several times on my thumb drive. First times were on 8 GB thumb drives.
I noticed I could not save anything as when I rebooted, it was all gone.
So, I got a 30 GB drive, tried installing again… and same thing.
Now I've found out I am running a LIVE version… not actually an installation.
So, for the somewhat novice who cannot do command-line installs,
step by step is there a way to install ubuntu-12.04.3-desktop-i386.iso using, unetbootin-windows-585.exe to a 30 GB USB stick using my Windows 7 machine?
