Force BootCamp to use GPT I have installed BootCamp manually to the last partition on my SSD /dev/disk0s13. It works, no problems, but every time I manage my partitions from OS X (or any other OS that is not Windows), the computer creates a new hybrid MBR, which makes Windows unbootable because it can’t find the Windows partition. I have to manually remove hybrid MBR via gdisk every time I manage my partitions.

I have a MacBook Pro 2015 13" Model with 512 GBs of storage and has 6 Operating Systems installed on it. I have macOS High Sierra and OS X Yosemite installed. I mostly use High Sierra.

Is there any possible way to either stop OS X from creating hybrid MBR or force Windows to use GPT? By the way, I'm using Bitlocker, not sure if it makes a difference.

UPDATE 1: I was trying to reproduce hybrid MBR with Disk Utility, and I discovered Disk Utility no longer produces that problem. Not sure about GParted.
If you have hybrid partitioning, then Windows will only see the partitions defined in the MBR table. There is no workaround for this. High Sierra removes hybrid partitioning in favor of a fully protected MBR. Yosemite can convert to hybrid, especially if partitions 2, 3 and/or 4 in the GPT are type EBD0A0A2-B9E5-4433-87C0-68B6B72699C7.


  Note: Type EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 will appear as Microsoft Basic Data in output from diskutil list.
