I seem to be running into a strange issue with my partition sizes.  I went into disk utility, hoping to resize my Bootcamp partition.  I selected the parent drive Macintosh HD > Partition.  The Utility shows I have three partitions, and that the drive is full, disabling the Partition area.  However, if I select one of the partitions (Macintosh HD or BOOTCAMP), each has free space (see images).  Macintosh HD has 2+ TB free and BOOTCAMP has 5 GB free. 

 

I have tried doing a disk repair, but nothing gives.  I can't figure out why there are two Macintosh HD partitions listed when I select the parent, and why I cannot remove one of them or merge them together.  I am using a 3TB Fusion drive. Images below display the varying free space according to disk utility. Any thoughts?

Since you attempted to use Disk Utility on a disk with a BootCamp partition, the partition map for the disk is totally corrupt.

 

The only way I know to fix it now is to repartition the whole drive to a single partition

 

Then reinstall OS X

 

Restore all of your data from your backup

 

Create a new BootCamp partition

 

Reinstall Windows

 

Restore data from Windows backup
