Hi guys,
I think I've got similar problem. I was removing boot camp partition (windows 10) with boot camp assistant and it was interrupted. My Macbook Pro (13' early 2011, el capitan) just restarted.
Now I've got one partition (macintosh hd) which I can see in disk utility, but ~70GB of disk space is missing. Can you help me with recovering it or do I have to do clean install?
