Description Ulrich Windl 2005-10-10 15:00:43 UTC

After update (from 9.2) on /dev/sda9 (2nd disk) GRUB has been installed in
/dev/sda9 (as before), but silently also to /dev/hda (1st disk). In my special
configuration, this caused only the new system to be listed for booting.

My configuration before update was this:
/dev/hda: LILO in MBR, hda1 is Windows/XP, hda5 is FAT32 (data)
/dev/sda: boot partition is sda1, root in sda5, sda6 is swap, sda7 is home, sda9
is the experimental system with GRUB in the pertition's boot sector
(GRUB on sda9 is started from LILO on sda1 (via MBR of hda))

After update /etc/grub.conf had install instreuctions for both, sda9 and hda.

Can you please attach the /var/log/YaST2 directory (as a tar file)?
Please take a look at http://www.opensuse.org/Bug_Reporting_FAQ#YaST
if you have any problems.

Comment 2 Ulrich Windl 2005-10-12 06:38:02 UTC

Please see ttachment #53799 to Bug #121990. (I think it makes little sense to
attach the same file multiple times.)

Comment 3 Jiri Srain 2005-12-15 12:11:10 UTC

Reasigning to new maintainer

Comment 4 Ulrich Windl 2006-01-23 07:25:15 UTC

Ststus update: The problem happened again for the recent GRUB online update, resulting in unbootable Windows (until repair).

Comment 5 Torsten Duwe 2006-04-03 12:36:38 UTC

According to your Yast2 logs, lilo is used to boot the system!?
Can you paste /etc/grub.conf from /dev/sda9 here?

Comment 6 Ulrich Windl 2006-04-03 13:52:00 UTC

Providing grub.conf from /dev/sda9 is quite difficult, because I've sold the PC in the meantime and /dev/sda is lying around outside of any PC. I'll see if I can arrange some access to the hardware.

Comment 7 Ulrich Windl 2006-04-13 08:55:28 UTC

Created attachment 78150 [details]
/etc/grub.conf from /dev/sda9

Revived /dev/sda to get the file

Comment 8 Ulrich Windl 2006-04-13 08:57:48 UTC

Notes to comment #5 and comment #9: /etc/grub.conf may be rewritten during online-update. Maybe I changed it after that. I can vaguely remember two "setup" lines: One for /dev/hda, and one for /dev/sda9

Comment 9 Torsten Duwe 2006-04-21 14:19:18 UTC

There's no way an RPM update of grub changes your /etc/grub.conf . If update via YOU or similar does that, please re-open. The attachment from Comment #7 is perfectly fine and will leave your MBR intact, agreed. When /dev/hda reappears, re-open.
