I've created a USB startup disk from a live cd version of 8.10. When I try and boot from the USB stick it simply displays the message "Grub" and boots no further.

I have the additional problem that the computer I am using is currently HD less. I do have two USB sticks though, one for getting ubunutu on and another smaller one for saving files temporarily.

Any ideas or pointers. I've spent a good few hours on this and gotten no where.
