out of disk grub rescue

[fresnofred]

I installed ubuntu 12.04 to a 32 gb thumb drive. i did this by disconnecting my hard drives on my pc to try to avoid grub errors. when i boot to the flash drive i just get "out of disk" message and grub rescue. however, when i boot it to other laptops i have it boots successfully. any ideas as to what may be happening?

When you try to boot from usb sometimes it can happen that the usb is not detected fast enough. I don't whether that is the case.
