I have a MacBookPro 13" Retina late 2013 with an internal SSD, there is 1TB unallocated space, I tried Disk Utility but it doesn't let me create a new partition there (it just does nothing when I click 'Apply'). Verify shows no error, also repair.

I've booted with CMD-R, can I unmount the disk0? I guess not, but I'm not sure.

I've created an usb stick with OS X 10.9 but the notebook could not boot from this stick.

Is there a way to make a new perdition from the existing free space with diskutil?

If solved the problem by - Boot with ALT CMD P R After this the former bootcamp partition was again there. - New partitioning of the ssd with only one partition having 1TB - By using Web-recovery installation of Mac OS X - Creating a new bootcamp partition with bootcamp assistent.

My concern was when remove the partition disk0s2 (with recovery OS X) a new installation of Mac OS X is not possible, I wasn't aware of the function Web-recovery.
