Can't Boot Backtrack 5 from USB.

[Mystery]

I installed Backtrack 5 KDE 64 bit on to my 2 gb USB using Unetbootin. When I restart my laptop and try booting into Backtrack, I get this:



I've tried using Backtrack 5 KDE 32 bit, and gnome as well, but it gets stuck at the same spot. I can't type or do anything when it gets there, its just frozen, so I just restart my computer. I have a Toshiba Satellite A305-S6916 running Windows 7 64 bit.

Display Adapter: ATI Mobility Radeon HD 3650
Processor: Intel(R) Core(TM)2 Duo CPU T6400 @ 2.00GHz
Network Adapter: Intel(R) WiFi Link 5100 AGN

Does anyone know how to fix this? Is it maybe cause the usb is to small?

I appreciate any further assistance.
