Somehow, I installed grub2 instead of grub - the machine now works properly once grub (not grub2) was installed.

I needed to run "update-grub" for my menu.lst to be created and everything to go back to normal.

Hi,

This stacktrace corresponds to a very old version of GRUB (February 2008). It's likely we already fixed it in upstream.

Please can you try with a recent version?

I'm not really sure I'm having the same bug. I attach the apport-crash information if it helps. And this is the partition layout:

root@ubuntu:~# parted /dev/sda print
Model: ATA SAMSUNG HD103UJ (scsi)
Disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
 1 32,3kB 908GB 908GB primary ext3 boot
 2 908GB 917GB 8587MB primary linux-swap
 3 917GB 958GB 41,7GB extended
 5 917GB 917GB 115MB logical ext3
 6 917GB 938GB 21,5GB logical ext4
 7 938GB 958GB 20,1GB logical ext4

Given that this is a MacPro and therefore presumably GPT, I think this is probably the same as bug 207876, fixed upstream as follows:

2008-02-17 Robert Millan <email address hidden>

        * util/i386/pc/grub-setup.c (setup): In find_first_partition_start(),
        set `first_start' to 0 for non-PC/MSDOS partition maps.

Àlex Magaz, your problem can't possibly be the same as this one as the function in the original reporter's stacktrace had been entirely rewritten by well before Ubuntu 9.10. If you're still having this problem with a current version of Ubuntu, please file a fresh bug report.

[Colin Watson (cjwatson)]

Oops, I quoted the wrong ChangeLog entry. I meant to say:

2008-02-16 Robert Millan <email address hidden>

        * util/i386/pc/grub-setup.c (setup): In find_first_partition_start(),
        do not assume partition map is PC/MSDOS before performing checks that
        are specific to that layout.
