This is the version of GRUB from Ubuntu 10.04 LTS, not from either 10.10
or 11.04. What's probably happened is that your system is misconfigured
to install the boot loader to the wrong place, and at some point it
ended up confused enough that it tried to load half of one version and
half of another, which meant it couldn't proceed. The fix is usually to
use https://help.ubuntu.com/community/Grub2#METHOD%203%20-%20CHROOT with
a live CD to fix booting, and then 'sudo dpkg-reconfigure grub-pc' once
you're up and running and make sure that the boot disk is selected;
admittedly complicated but it should only be a problem for people with
relatively complex disk setups.
I don't believe that the underlying cause for this - the wrong data
being recorded by the grub-pc package about where the boot loader should
be installed - is still an issue in 10.10 and later. Unfortunately,
some old bugs have hung around on a few upgraded systems.
It's not clear to me that this is the same problem that afflicted the
original reporter of this bug. The upstream GRUB manual has some
general advice on this condition:

While it is possible to reinstall Ubuntu without losing personal files,
you have to be really quite careful, and it is always sensible to take
full backups before reinstalling an operating system. It's easier in
Ubuntu 11.04, which comes with an "Upgrade Ubuntu <previous version> to
11.04" option which ensures that personal files are preserved.
I'm sorry for your loss of data, but it wasn't a direct result of this
bug.
