The menu.lst does not exist in the MBR.  Check the grub manual for details.

Reinstalling is not needed.  If anything this will cause you even more
grief until you get a handle on grub.

First thing to do would be to understand how grub and boot loaders work.
 You will also need to understand partitioning before you dig into grub.
 Wikipedia is actually a good place to look for these topics.

The manual for grub can be accessed via a terminal with "info grub".
Alternatively the manual is posted online if for some reason you find a
browser or PDF easier to read:
http://www.gnu.org/software/grub/manual/

Honestly, I no longer even dual boot.  I personally do not see a benefit
to doing this.  I am not suggesting that you do not have a valid reason,
only that it makes no sense for me and my work flow.
