I'd like to fully install Ubuntu 12.10 onto a 16GB USB 3.0 flash drive, not create a live USB but to treat the flash drive as an external hard drive. I've read it's possible and I know my computer can boot from it. However, it doesn't work when I try. I've booted a Live USB from another flash drive and installed Ubuntu onto the 16GB one.
I'm trying to boot Xubuntu from USB Flash Drive on my old laptop Fujitsu-Siemens but it shows "Missing Operating system. Operating System not found". Although the Flash Drive works on my current laptop.
Can I make DOS USB Flash Drive with (x)Ubuntu Live CD on it?
I tried various windows programs to make a bootable USB, and Xubuntu Startup-disk without success.
