View Full Version : [ubuntu] [SOLVED] adding latest kernal to GRUB

October 21st, 2008, 05:39 PM
I installed HH from a purchased DVD and applied all updates. I have Suse 10.0 on the first drive and HH on the second and made an entry for Suse in my GRUB menu. after a vacation I installed all the waiting updates which included a new kernal. I kept my old menu so I would not lose my Suse entry.
How do I go about adding the new kernal to GRUB?

Copy the /boot/grub/menu.lst file to your home and type

sudo update-grub
This makes grub re-read it's menu file, which adds the new kernel and an entry for your SuSE partition.

That did not work. I still only have .16 and .19 on the menu. The updates I did included .21 but it is not on the menu. I did not do the automatic changes because of the reason I gave in my original post.

Hi Tom, if you want to make sure your Suse entry does not get modified, you can either put it before the lines:

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below
Or you can put it after:

### END DEBIAN AUTOMAGIC KERNELS LIST
Then you can use the "update-grub" command safely to update your Grub menu with new kernels while the Suse entry shouldn't be touched. To successfully use the update-grub command, make sure that at least the "groot" line uses (hd1,0), or your Ubuntu partition:

# groot=(hd1,0)
Even though it is "commented" with the pound sign, the update-grub script uses that line to know where your Ubuntu is located. Also, did you confirm by looking in your /boot directory that you have the new .21 kernel update? You can always manually add an entry for the new kernel with:

title Ubuntu 8.04.1, kernel 2.6.24-21-generic
root (hd1,0)
kernel /boot/vmlinuz-2.6.24-21-generic root=UUID=16fe3a84-6e50-441d-a800-314ae5ce59dc ro quiet splash
initrd /boot/initrd.img-2.6.24-21-generic
quiet
Let me know how it goes. :)

I saved the menu.lst file under menu.lst.save. I moved the Suse entry below the DEBIAN markers. and saved the file. I reran the update grub and it still did not have the .21 listed.

Here is my /boot dir.

OK, so you ran update-grub as root, i.e. "sudo update-grub"? How about posting the full contents of your menu.lst, because one of the options used by the update-grub script might be off. Also, can you post the output of running the sudo update-grub command?

That's really bizarre that the update-grub script found the new kernel, but it doesn't look like it updated the menu.lst. Try manually opening your menu.lst with:

gksudo gedit /boot/grub/menu.lst
And change the line that has "# groot=(hd1,0)" to arbitrarily be:

# groot=(hd1,5)
Then run:

sudo update-grub
And look at the menu.lst to see if all the Ubuntu entries now use (hd1,5) instead of (hd1,0). If they don't change, then we will know that the update-grub script is for some reason not updating that menu.lst. Please also post the output of the update-grub command.

As you can see it did not change.
I will reedit it to its previous entry, ie. hd1,0

Thanks for all your help!

Yes, that is really strange that update-grub didn't change the menu.lst. How about reinstalling Grub; note that it won't delete your menu.lst or Grub files in /boot/grub/, but maybe it will fix the problem with the update-grub command:

sudo apt-get purge grub
sudo apt-get install grub
Next post the output of:

ls -l /boot/grub
Where "-l" is a lowercase L. Then change the groot line in the menu.lst to (hd1,5) again and run:

sudo update-grub
And please post the output of the update-grub command. After that, check your menu.lst and let me know if the Ubuntu entries use (hd1,5).

That Worked !!!
it found .21, changed to hd0,5

I have changfed it basck to hd0,1 and everthing is ok
