I have just finished a succesfully upgrade from 10.04.4 to 12.04.1 on my remote server. After reboot, I have verified that it is still booting from the old kernel:

$ uname -a
Linux socrates 2.6.32-41-generic-pae #94-Ubuntu SMP Fri Jul 6 17:08:20 UTC 2012 i686 i686 i386 GNU/Linux

I have also run update-grub:

 $ sudo update-grub
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
Found kernel: /boot/vmlinuz-3.2.0-29-generic-pae
Found kernel: /boot/vmlinuz-2.6.32-41-generic-pae
Found GRUB 2: /boot/grub/core.img
Found kernel: /boot/memtest86+.bin
Updating /boot/grub/menu.lst ... done

But it is still booting from the old one... I have verified that I am still running grub Legacy:

   dpkg -l grub* | grep ii
ii  grub                                 0.97-29ubuntu66                     GRand Unified Bootloader (Legacy version)
ii  grub-common                          1.99-21ubuntu3.1                    GRand Unified Bootloader (common files)

You already have installed grub and grub-common

Before you install grub-pc, you could install boot-repair, then call it as an application and automatically export its log file to 'http://paste.ubuntu.com' without modifying anything. This log file perhaps detect some errors, you can even post a link to it.

Cannot overwrite Debian6 grub, with Ubuntu grub2 

Use sudo grub-install /dev/sdX X is the drive letter ex:- a, b You can find it out by doing a sudo fdisk -l

Then do a update-grub2

You can use again boot-repair and export another log file without modifying anything

I fixed this by installing grub-pc.
Thanks.
