I'm running Ubuntu 12.4 on a 8GB thumb drive. Every time I restart I lose my settings because I don't have enough room. So I want to install it on my 160GB external USB drive (FAT32). My issue is, I have over 100GB stored on it and have no where to back it up. So I want to partition only 40gig for the system install without losing any of the data already on USB.
Is this possible?
