You can't just run "update-initramfs", you have to run "update-initramfs -u".

Also, if you don't pass a "-k .." argument, only the latest kernel's
initrd is updated.

It's not clear from the OP whether it's grub1's or grub2's stage 1
that's in the mbr. I can't think of a scenario whereby it's grub1's
and that menu.lst isn't updated or that it's grub2 and that it's
menu.lst that controls the grub boot menu, but I assume that it's
possible.

As Goh says above, his suggestion should rectify your problem but
could you post the output of boot info script to understand what's
happened?
