Unable to merge partitions

I'm trying to merge two Journaled HFS+ partitions, but I keep getting this diskutil error: "Merging partitions encountered error Could not read partition map (-9988) on disk disk0s4 disk0s3. The erase will not occur.".


How do I solve it? I'm already out of space in the OS X partition, and I'm dual-booting it with Windows 7 (which was installed first), using a single hard disk.


A screenshot is attached.


Thanks in advance.





What. The. {censored}.

I just restarted my PC, and got this "chain booting error" when I triedto boot OS X. I checked GParted, and my goddamn OS X partition is gone. When could it have been deleted? While I was USING it?
