Ubuntu setup problems

[PoshBoyGames]

I've installed Ubuntu setup on a USB drive using the instructions on the site. When I boot onto the USB drive I get a menu with "GNU GRUB  version 2.02^beta2-9" on the top. There is four options saying;

 

"Try Ubuntu without installing"

"Install Ubuntu"

"OEM Install (for manufacturers)"

"Check disc for defects)"

 

then at the bottom it says "Use the up and down keys to select which entry is highlighted.

Press enter to boot the selected OS. 'e' to edit the commands before booting or 'c' for a command-line. ESC to return to previous menu."

 

When I select any of the four options it just goes to a black screen, then I reboot.

 

I can't seem to find anybody else with the same problem, is there a fix?
