hi,
i have the same problem with ubuntu 12.10 and 13.04, i can boot on the usb stick but when i try ubuntu without installing i get a kernel panic.

i've tried all the usb ports and they all fail.

i have no cd to burn

ps: i have no linux already working system

Hi,

is there a grub option to boot ubuntu 12 or 13 from a usb 2 usb stick on a usb 3 port motherboard ? (without getting a kernel panic)
