So the question is, how did Grub Legacy get there? Your grub.cfg file menuentry lists "GNU/Linux" as the OS rather than Ubuntu which I've never seen before on an Ubuntu installation. THis should not prevent booting as it is just the title and the kernel and initrd lines are different in grub.cfg compared to menu.lst. Check which kernel version(s) you have. You should be able to re-install grub2 using the methods described at the Ubuntu site at the link below under Section 2.2 under Contents.

@yancek
So if I install grub2 it will then take precedence over grub or will I have to exe anything for my system to use it ?

Here's what I mean:
If my system has grub and not grub2 can I simply install it and will the system the automatically use it ?
As on the page you quoted above see another link https://help.ubuntu.com/community/Grub2/Upgrading

The first line in the bootinfoscript output quoted below shows Grub Legacy in the MBR pointing to the Grub files on xvda. Although you have a grub.cfg file, it is not being used as if it would that line would state so.

Grub Legacy (v0.97) is installed in the MBR of /dev/xvda and looks on the
same drive in partition #1 for /grub/stage2 and /grub/menu.lst.
