Hi there;

 

I have a macbook pro 13" 9,2 from mid 2012 with a 500 GB hard drive. I used Boot Camp Assistant to make a partition for Windows 7, 100 GB in size. It worked fine. I then decided to install Fedora Linux as a third operating system on a third partition. This failed hopelessly, and also made Windows unbootable. So I used Disk Utility in OS X to delete the BOOTCAMP partition, and as many of the other partitions created through my Linux attempt. Now I have my Macintosh HD partition (running OS X) using 350 GB of space on my hard drive, a useless 4 GB partition called disk0s4 that I is not erasable via Disk Utility, and 150 GB of empty free space.

 

I want to restore my OSX partition to it's full size (500 GB), erase all other partitions, and try again with a different OS. However Disk Utility won't let me resize my Macintosh HD partition to be any bigger than it already is. Boot Camp Assistant won't help either, it gives me an error message. Here is my disk utility screen shot:

And here is the error message from Boot Camp Assistant:

Any help is appreciated. Thank you!

MacBook Pro, Windows 7
