Hi all,

I had to reinstall one of my systems, as it didn't get up any more.
After reinstalling from dvd, i powered cycled to test grub.

Then powered down, reconnected data-didks, and powered up again.
Did an online update, i presume there were kernel packages, as yast
wouldn't let me activate nfs-server: it complained i had to reboot

So i did, and got no further then just: "grub" ;-(
Unfortunately, the dvd does not contain the "repair" option,
which might be handy with the new grub2.

Disconnecting the data-drives and reboot doesn't help either.

After restarting in "rescue-mode" from the dvd, it looks like the fs is
ok, after mounting it manually i caninspect parts
like /boot/grub2/grub.cfg.

Question remains why it went wrong after the update?

The manual just says:
""Bootloader Configuration after a Kernel Update

Every time a new kernel is installed, the perl bootloader writes a new
bootloader configuration file using the defaults specified
in /etc/sysconfig/bootloader. If you are using a customized set of
kernel parameters, make sure to adjust the relevant defaults

But i requested nothing fancy from grub2, just let yast2 do the

Any suggestions (to repair and to avoid it the next time) are welcome...

Some further info.....

After rebooting i got to "GRUB", but not into the grub shell, system

Somewhere i read that i should try "grub2-install /dev/sda"
But all i got was:
"mkdir: can not create directory []/boot/grub2/i386-pc[] : read-only
file system"
Which is a bunch of crap, as i could mount it manually, create files,
fill them with text, write back to that directory and remove them.

next i did:
mount /dev/sda3 /mnt (sda1 is swap, sda2 is sles11sp2)

mount -o bind /proc /mnt/proc
moutt -o bind /dev /mnt/dev
mount -o bind /dev/pts /mnt/dev/pts
mount -o bind /sys /mnt/sys
chroot /mnt


grub2-install /dev/sda

This time no warnings or errors, and after a reboot the system is back.
powered down, reconnected data-drives and after a reboot everything
still seems to work ...

Don't know if anybody else came across it, but this seems to be a
