I tried to install Ubuntu on my MacbookPro (mid 2015, OS X Yosemite) dual boot, using the following: How to Dual-Boot OS X and Ubuntu (PDF)
I was finishing up part 3 and Ubuntu was starting to download, until everything froze. Nothing was responding so I force shutdown my computer and now OS X seems to be working fine. However I have a partition disk0s3 (Linux Swap) and a bunch of Free Space I can't get rid of.
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *251.0 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 182.6 GB disk0s2
3: Linux Swap 16.4 GB disk0s3
I tried getting rid of them through Internet Recovery but that didn't work either. How can I get rid of the partition and the Free Space?
