Package: grub-efi
Version: 1.96+20080724-16
Followup-For: Bug #427492
I can confirm that this is a problem. Just installing grub is not
sufficient to boot.
I am using this method:
1) load GRUB from the OSX partition
2) load GRUB from the Linux partition using the grub installed on the
hfsplus partition.
Perhaps in 2) I could just load the Debian configuration file. Since the
Debian grub is broken after some upgrade it might be a good idea to set
up booting this way to avoid future problems.
It must be possible to "bless" a disk without modifications to the
NVRAM because bootable CDs and disks can be swapped between systems,
connected to different buses (IDE/USB/FireWire), etc.
Unfortunately I cannot point to a piece of documentation describing how
this is done. In fact I was even unable to bless grub installed in the
EFI partition.
On the other hand, this does not really require reverse-engeneering as
the OS X system base is Darwin which is opensource.
Thanks
Michal
