Description Jurgen Kramer 2011-09-16 07:44:44 UTC

Description of problem:
EFI booting from F16 installation  on the MacMini5,1 no longer works with the latest grub releases (see also BZ #731529)

Version-Release number of selected component (if applicable):
grub-0.97-77.fc16

How reproducible:
always

Steps to Reproduce:
1. Boot from F16 installation media
2. Select EFI boot option

  
Actual results:
The system hangs when selecting the EFI boot option

Expected results:
grub starts normally in EFI mode. No hang

Additional info:
grub-0.97-75 was the last version which worked correctly on the MacMini5,1

Newer macs with Lion use 3 partitions (EFI,system,restore) leaving only one spare MBR partition. Legacy boot / MBR partition scheme is no longer a viable option on macs.

Preliminary test with grub-0.97-78.fc16.x86_64 indicates my EFI boot problems are solved. (tested with efiboot.img written to usb disk with grub.efi from 0.97-78 put in the EFI/BOOT directory).

Comment 2 Peter Jones 2011-09-28 15:24:18 UTC

Given that I'm going to go ahead and call them the same problem (which from a code perspective also seems somewhat likely).

I'm going to close this one dup since there's more testing discussion going on over in the other bug.
