I have the same kind of issue than here : Create new partition in unallocated space with diskutil
but on disk0 ! I don't know what to do anymore :(
So i can't modify anything with gpt. I had Ubuntu installed on a partition, deleted it with Disk Utility which got stuck during the process, had to force quit. Reboot the mac, and that's when it became weird :
Recovery HD was no more hidden and mounted as a standard partition on my Desktop, 20GB of the former Ubuntu partition vanished !
I tried the functions activated in the Debug Mode of Disk Utility, resetting PRAM, BootCamp tells me "the startup disk cannot be partitioned or restored to a single partition", and nothing different when booting on Recovery HD to use Disk Utility.

I don't even have the grey zone for the unallocated space like on this post : How can I resize a partition with Disk Utility?
