Description John Reiser 2012-03-27 15:06:08 UTC 
Description of problem: The BIOS boot partition (code EF02) should not be created nor used (for grub2 image) when booting with combined GPT and (U)EFI.  Instead, the file /EFI/redhat/grub.efi on the EFI System Partition contains everything that is needed.  Creating a BIOS boot partition wastes 1 of the 15 available partitions.  (15 partitions is a limitation of Linux, not the GPT.)


Version-Release number of selected component (if applicable):
anaconda-17.14-1.fc17.x86_64


How reproducible: every time


Steps to Reproduce:
1. During install, then partition a GPT disk on a (U)EFI box.
2.
3.
  
Actual results: The installer demands (and creates if necessary) a BIOS boot partition, code EF02 (revealed by gdisk), size 1 MiB, and puts an image of grub2 on it, and uses that image for booting.


Expected results: Do not demand or create a BIOS boot partition.  Instead use the /EFI/redhat/grub.efi on the EFI System Partition (code EF00).
