I decided I no longer wanted the Bootcamp partition I created so, using DiskUtility, I deleted it. I then restarted the computer, selected to install the updates, and the computer froze. I did a hard restart, was treated by the apple logo and the boot bar. The boot bar progressed to 3/4 of the way and the computer shut down. I booted into recovers and ran first aid on the device; everything came back OK. Any ideas?
