Force Shutdown during boot camp partition process. Left with no space on mac and no partition.

I opened boot camp assistant.

I clicked continue on the bootcamp introduction screen.

It asked me to select one:

a) Download the Windows support software for this Mac

b) I have the Mac OS X installation disk that came with my Mac or I have already downloaded the Windows support software for this mac to a cd, DVD or an external disk.

I selected b, and then partitioned as much as I could.

The loading bar reached approximately halfway.

My macbook pro then froze with the spinning rainbow of death as my cursor.

I force shutdown by holding down the power button.

I turned the computer back on, and I saw that my mac only has 9 GB left.

I check Disk Utility. It says 100% of hard drive is my macbook pro, no windows.

Any fix? Help me get my space back. thanks.
