I new buy mac mini 2012. I have osx mountain lion.

When I create a partition get error "Partition Error". "Couldn't unmount disk"


I haven't OS now. Because I removed its. 

I can't create partition under 500 GB HDD.

And I'cant see Recover HD.

My disk Utility Screen:



When I create partition I get below error pop-up message.


When I browse for Image I see Recover HD.



finally. "diskutil list" typing in terminal  list disks.





Mac mini, OS X Mountain Lion (10.8.2)
