Updated my Gutsy installation this morning....and after 150+ megs of
files (including new Kernel) Grub managed to mess up the menu file. It
referred to HDA3 as the root.....when it's always been SDA3 under
Ubuntu anyway.

Hello Frank,
No expert here, but have just done last gutsy update
installing new kernel-image 2.6.22-15-generic and
didn't experience your problem. However, am using
UUID's instead of /dev/names which is supposed to
eliminate the issue. I believe using UUID is the
default now since before gutsy or at least since
gutsy.
Perhaps you manually changed /etc/fstab or somehow
elected to stay with dev names. Using UUID's ipo dev
names should resolve your problem.
Hope this helps. Sorry, can't tell you how to use
UUID' if you don't know how. Someone expert will have
to do that.

Nope, didn't change anything in fstab. Dunno why UUID's are not used on
my machine.

It's Gutsy and has been used since I updated it was released.
I had to change menu.lst after the last update as the machine
wouldn't boot because the old menu.lst referred to root as hda3 when
Ubuntu wanted sda3 ( it's an IDE drive ).
This is the current menu.lst.
The first items are for my Debian Sid system.
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0,
# and the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default
# entry is the entry saved with the command 'savedefault'.
default 0
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default
# entry (normally the first entry defined).
timeout 15
# Pretty colours
color cyan/blue white/blue
## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive
# editing control (menu entry editor and command-line) and entries
# protected by the command 'lock'

The top is your boot and it has no root=UUID= and this confuses the
system sending you a new kernel. I have not updated my Gutsy but will
today and expect zero problems.

Here is how you get a uuid id:
When you know which partitions you want to get a UUID word for you
just do this:
So do this and change both the root in menu.lst and also the listing in
/etc/fstab. This should do it.

Is this the file /boot/grub/menu.lst of your Ubuntu installation or is it
from your Debian installation? There is a huge difference because if it
is from your Debian installation, the update-grub script for Ubuntu
shouldn't touch it at all. It looks like it isn't from Ubuntu Gutsy
because otherwise the kernel used in the automagic kernel list would be
2.6.22-* not 2.6.24-*. If it is from Debian, you would have to manage the
Ubuntu part manually, and your problem doesn't come from Ubuntu but from
Debian because the Ubuntu script wouldn't see your menu.lst.

Well I just got my updates from a few weeks worth and it included a
kernel and Gutsy is up and running after a re-boot. What you say Nils is
Frank may have put a Debian kernel in his Ubuntu? I thought he got the
update and it didn't work after a re-boot.
