During my daily upgrade, Grub2 was installed. During the installation, I was given the option to chainload Grub2 from the Grub-legacy menu.lst file. I elected to try Grub2 in this manner. My menu.lst was backed up and a new menu.lst was written. The new menu.lst has a stanza to chainload to Grub2. In Grub2, the menu is populated from /boot/grub/grub.db. This file contains only the stanzas for sda1.

update-from-grub-legacy , update-grub, update-grub2 were not installed although man pages for these were installed.  Not able to install with update-from-grub-legacy.  Running a reinstall on grub-pc completed the install.

You mean grub.cfg not grub.db
It's upgrade-from-grub-legacy.
What does your apt or aptitude log show about that?
And the dpkg log?
(All in /var/log/)
If the package gets successfully installed but not all files from it
exists on the system, this would be a dpkg bug.

I performed similar task  (dist upgrade to squeeze) and ended up with the
chain loader (what I wanted).

the chain loader to grub 2 worked just fine, I was happy with the operation of
grub2, everything appeared to work correctly (all boot options checked out),
so followed the option to remove grub-legacy....

upgrade-from-grub-legacy

after which system failed to boot, no menu options where prescented....
Problem resolved by booting from a live CD, chroot to my linux partition then

grub-instal /dev/sda


Sorry can't remember exact grub error message...

Additional:
having run grub 2 for about a week now the bootloader failed again.  this time
Grub 2 would start but would inform me that it couldn't find any installed
modules, continuing would prescent the usual BIOS can't find system disk error

grub-instal /dev/sda

appears to have recovered the system, and I once again have my boot options
for a few kernels, 'doze and 'doze re-install on the lappy.
