I did the same thing just to recover 51 GB space for my Macintosh HD drive but it turned out to be a nightmare for me.

I obviously wanted to delete Boot Camp to reclaim Boot Camp partition space after deleting Windows.

Step 3 : Though this will delete the entire Boot Camp partition, but space will still not be recovered. See the screenshot above, Macintosh HD is still 69 GB and remaining 51 GB is unused. Let me add icing to cake, you are not even allowed to drag down the Macintosh HD slider. Bam!

Don’t worry, just tap on “+” sign and there’ll be another drive “Macintosh HD 2“. Use the slider to decrease the space used by Macintosh HD 2 and it’ll eventually increase the size of Macintosh HD.
