Problems with Bootcamp, where did my storage space go?

I hope someone can help me here!
I started making a Windows partition using BootCamp. After a while, my macbook totally froze, and after a few hours of being totaly frozen, I had to turn it of. When I restarted the computer, and Bootcamp, it seems like the partiotion is nowhere to be found, but the storage space I wanted to use for it, is used. How can I delete this? I am not able to do it in Bootcamp or via Disk Utillity.

Please help me!
