/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

You can remove the 2nd partition and then enlarge the 1st partition to recover the space, but not the other way around.

You can clone your 2nd partition to an external drive, then repartition your internal drive to one partition, then clone from the external back to the internal.

Or, you could clone your 2nd partition back to your 1st partition, then erase and remove the 2nd partition. Then enlarge the 1st partition to recover the space previously used by the 2nd partition.

I have exactly the same problem. Did you got to fixed?

I am trying to merge the partitions on Diskutility so it will let me install windows again. (My old windows partition got damage so I erased the partition to try to install a new copy). The problem is that Bootcamp doesn't let me installed unless my I have only one partition.

(It basically saids that I must have my volume in one partition to install windows)

I have tried to merge the partitions in recovery mode, but nothing. I also tried to merge them using the live CD Gparted, but no patter what type of partition I put, It never let me resize the OSX partition, even I leave the other partion Unformatted. I also formated the partition as MS-DOS (FAT) to try to cheat on boot camp ,but nothing either.....

Any clues?

This is driving me crazy....

If you used Bootcamp then you should use the Bootcamp assistant to destroy the Bootcamp partition and devolve that space to the mac side.

You need to clone your mac partition to an external drive, and completely erase your system drive, as a single partition.

Then clone your system back and, if desired, then use bootcamp assistant to create a windows partition.
