Partition lost after Boot Camp assistant crashed
Hello,
I just ran the Boot Camp assistant on my 13" MacBook Pro Retina 2015 and told him to install Windows 8 from an .ISO file. I set it up so that my 120 GB SSD should be partitioned to a 90 GB partition for the existing OS X 10.11 and install Windows on a newly created 32 GB partition.
During the partitioning the MacBook crashed and rebooted. Now I have a 80 GB partition left, on which OS X is installed and the remaining 40 GB vanished. They are not shown in the Disk Utility and I can't create any new partitions on the 120 GB SSD in the Disk Utility.
Is there any way to restore the OS X partition to the full 120 GB or rescue the missing 40 GB and install Windows on it WITHOUT having to reinstall OS X again?
Thank you in advance for any help!
