My mac (running El Capitan) has recently run out of storage space so I have been trying to remove my bootcamp partition to restore the full capacity of the OS X partition.
When I try to remove it through the bootcamp assistant I receive a message saying
An error occurred while verifying the file system. Please reboot into
recovery, repair the disk with Disk Utility, then try the operation
again.
I have tried to boot into recovery and repair the disk, however, it says everything has been repaired and the bootcamp assistant still fails.
After this I went into terminal and ran diskutil list
with the output:
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *251.0 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_CoreStorage Macintosh HD 174.4 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
4: Microsoft Basic Data BOOTCAMP 75.6 GB disk0s4
/dev/disk1 (internal, virtual):
#: TYPE NAME SIZE IDENTIFIER
0: Apple_HFS Macintosh HD +174.0 GB disk1
Logical Volume on disk0s2
01CA9FDB-EE71-4B65-9216-2A7EB5CBA511
Unlocked Encrypted
Next, I tried to erase the disk with diskutil eraseVolume fat32 BOOTCAMP disk0s4
which worked, however, I am still unable to merge the partition in Bootcamp assistant and I am given the same error message.
Any ideas on how to merge the partitions and remove the Bootcamp partition?
