Disk utility stuck on "Preparing disk partitioning"

Hello,

yesterday I created a Boot Camp partition and I installed Windows 8.1 on it. Then I realized that the 20 GB of the partition were not enough for me, so I made a backup of the Windows partition, and I deleted it. Now I'm trying to recreate it, but I'm unable to complete the process. The disk utility is stuck on "Preparing disk partitioning" or something like that (the OS language is Italian and I don't know how to translate).

The "Windows" partition is the one I'm trying to create. If I close the disk utility and stop the process, when I reopen this is the situation.

What can I try? Should I delete even the disk0s4 partition, expand the Macintosh HD one and then retry to configure bootcamp?

Thanks

MacBook Air (13-inch Mid 2013), OS X Mavericks (10.9.1)

Erase disk0s4 on left column and then do the partitioning.

Any thing I try to do now, I'm stuck on the "preparing" phase.

What can I do, please?
