Description of problem:

My MacBook4,1 triple-boots OS X, Windows and Linux. To get Windows to boot, a hybrid MBR is required. When I install F17 the hybrid MBR is replaced with a protective MBR, and Windows no longer boots.

This would be understandable if some of the partitions in the hybrid MBR were changed, since it would then be unclear what should be done with the MBR. However, in my case none of the hybridized partitions is affected, so the MBR should be left alone.


How reproducible: Always


Steps to Reproduce:
1. Setup a Mac with the following GPT partitions:

   i.   EFI system partition
   ii.  OS X HFS+
   iii. Shared FAT32
   iv.  Windows NTFS
   v.   Free space

The hybrid MBR contains entries:
   i.   EE - protective
   ii.  AF - OS X
   iii. 0c - Shared
   iv.  Windows

2. Boot from Fedora 17 Live Desktop USB in EFI mode, install to free space with default options

  
Actual results:

The resulting partition layout:
   i.   EFI system partition
   ii.  OS X HFS+
   iii. Shared FAT32
   iv.  Windows NTFS
   v.   Fedora EFI boot HFS+
   vi.  Fedora boot ext4
   vii. Fedora LVM

The MBR is protective, one giant EE partition. OS X and Fedora boot, but Windows does not.


Expected results:

The MBR should remain hybrid, referring to the same partitions as before. Windows should still boot.
