Loads BusyBox instead of Ubuntu

[Stonebot]

When I start up my computer the Wubi screen comes up and I select Ubuntu then it loads up to the splash screen loads for a tiny bit then it goes into a BusyBox thing.

I tried this but it didn't work:

The Ubuntu splash screen loads for awhile then exits to a BusyBox/(unutramfs) prompt

Reboot and hit Esc when prompted to enter the boot menu Hit 'e' to edit the first line. Next select the second line and hit 'e' again. Input 'irqpoll' towards the end of the bootline. Then hit 'enter' and then 'b' to boot.

So from there I had no idea what else to do so I came here. does anyone know the problem and how to solve it?
