Stuck on "please wait while Boot Camp Assistant is removing the partitions it created"

I tried to install Windows 10 on my Mac but it didn't finish installing because of a problem so then Boot Camp tried to "roll back the partitions" but got stuck doing that. Now in Disk Utility I have a partition named BC1 as well as my Macintosh HD. How can I get rid of/merge the two so I can get back the space I allocated for Windows?

Thanks!
