Grub not adding upgraded Kernel

[eddieg780]

I have upgraded my Kernel from 2.6.27-9 to 2.6.27-11 but there is no addition to grub for me to boot using 2.6.27-11. Wasn't this line supposed to be added to grub automatically?

Yes.

Re: Grub not adding upgraded Kernel

Open Konsole.
sudo update-grub


See if that does it.
See also
man update-grub
for more.

Make sure
# groot=
is correct in menu.lst.
It should point at the partition where the kernels are (the vmlinuz files).

- - - - -

Another option:

In menu.lst, make a boot stanza entry for the new kernel by copying the previous stanza and changing the kernel & initrd numbers.

- - - - -

Just to be sure about things, check your /boot directory and make sure the new vmlinuz and initrd are both there.

Re: Grub not adding upgraded Kernel

Thank you for your response. I tried Qqmikes suggestion and terminal said it found the other kernels and updated grub but they are still not there. Not sure how to do the stanza part though. Here is what my menu.lst says. What should I change. Thank you.

Re: Grub not adding upgraded Kernel

I figured out what making a new stanza meant and I did it. It worked great but why didn't grub update automatically? Is there an entry in my menu.lst (entered above) that needs to be changed?

Re: Grub not adding upgraded Kernel

So you need a stanza for 2.6.27-11.
First, make sure you have such a thing!
Look in /boot and look for vmlinuz-2.6.27-11-generic and initrd.img-2.6.27-11-generic.

Then copy you other stanza and adjust them for the new kernel
(the “boot stanza” is everything between the title line and the last line initrd ....):

title Ubuntu 8.10, kernel 2.6.27-11-generic
uuid 83cc1912-e9d0-4884-a7e7-86ea9e34551d
kernel /boot/vmlinuz-2.6.27-11-generic root=UUID=83cc1912-e9d0-4884-a7e7-86ea9e34551d ro quiet splash
initrd /boot/initrd.img-2.6.27-11-generic

title Ubuntu 8.10, kernel 2.6.27-11-generic (recovery mode)
uuid 83cc1912-e9d0-4884-a7e7-86ea9e34551d
kernel /boot/vmlinuz-2.6.27-11-generic root=UUID=83cc1912-e9d0-4884-a7e7-86ea9e34551d ro single
initrd /boot/initrd.img-2.6.27-11-generic


NOTES:
> I changed it a bit (I didn't use initrd (hd0,2).
> I added the uuid line.
> The uuid line tells GRUB where your kernels live, and should be the partition containing the /boot directory, and that is usually (for most people) the same as the partition where Kubuntu root filesystem is installed.
> IF you copy/paste this into your menu.lst, and IF it doesn't work (Error 15 or something else), THEN simply re-type it by hand (into menu.lst).


Since you are doing this, double-check that UUID, but I'm (almost) positive it's correct:
Open Konsole
type
blkid
and hit Enter
and make sure that UUID (above) is the one for the partition where your Kubuntu is located.
Each partition has a unique identifier, called the UUID (see Wikipedia).


Your menu.lst looks OK to me. The groot= line is important, it tells GRUB where your kernel lives.

# kopt=root=UUID=83cc1912-e9d0-4884-a7e7-86ea9e34551d ro
# groot=83cc1912-e9d0-4884-a7e7-86ea9e34551d
# altoptions=(recovery mode) single
# howmany=all
and all the rest, looks ok.

Try removing older kernels (you probably don't need 11 installed kernels)...search for packages named linux-image-*, and and start removing the older versions to see if that makes a difference.

Re: Grub not adding upgraded Kernel

Agree.

Also, first -- try running update-grub one more time, just like you did before.

Check your menu.lst for
#kotp=

and
# howmany=all
