Hi, I've tried to remove my windows 7 partition through the bootcamp assistant but the process hung on my rMBP. I left it running for about 4 hours and had to switch it off for transit. Now I cannot see the windows 7 partition in disk utility, and the bootcamp assistant does not have the option to remove the partition. I don't want to resort to full backup and reset just yet, as I'm pretty new to Mac and there is alot of personal files (especially photos and videos in iPhoto). Can anyone suggest a way to manually format the now 'hidden' windows partition and extend the OSX to cover the full drive? The rMBP in question is the i7 model 512GB SSD with dual graphics. I am on the latest OSX version and the windows partition is Windows 7 SP1.
