My Bootcamp partition will not boot. It won't mount either. It shows up grey in Disk Utility and cannot be mounted or restored.

Question

It appears some sort of hybrid GPT MBR error. It was the resut of of partition editing.  I have programs installed that were liscensed through a robotics program. I would not like to format it. I would like to atleast be able to mount it, and hopefuly boot it.
I looked at this but don't quite understand it.

Hello bechardj,
I would use the disk utility to verify and/or if needed repair the partition to help troubleshoot the issue
From the help menu item: https://help.apple.com/diskutility/mac/10.8/help/index.html
You can check a disk for problems without repairing it. If you used the disk to start up your Mac, verifying means that you don’t need to restart your computer unless you need to repair your disk.
As Disk Utility checks a disk for problems, your computer may become slow or unresponsive.
Open Disk Utility from Applications.
Select a disk or partition and then click First Aid.If you run First Aid on a disk, Disk Utility checks the partition maps on the disk and performs some additional diskwide checks. If you run First Aid on a partition, Disk Utility verifies the all the contents of that partition.
If Disk Utility tells you the disk or partition is about to fail, back it up and replace it. You can’t repair it.
Click Verify Disk. If Disk Utility reports that it appears to be OK, you’re done. Otherwise, you need to repair it Repair a disk.
All the very best,
Sterling
