I am trying to boot 12.0 Ubuntu using my 8GB usb stick. I installed MultiBootUsb software and installed 12.04 ISO on it. When I rebooted my desktop by setting usb boot option in my bios, I got "boot error" string on my screen.
What might be wrong? My current Ubuntu version:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 13.04
Can you please let me know if I am missing anything?
