Sorry, but this is a "no brainer".

The grub.cfg (and not grub/conf which you state) was created by the 
version of the oS you *just* installed.

But the grub.cfg of the oS which is *in* *control* of the boot menu from 
which you select which oS you want booted has *NOT* been changed to take 
into account the changes you made to the list of kernels.

I don't know which oS has the control but what you need to do is to go 
into *that* oS and run (assuming that it is a Linux distro and using grub2)-

sudo grub2-mkconfig -o /boot/grub2/grib.cfg

which will then pickup the info in *this*, the controlling oS, and also 
then pickup the info in the altered grub.cfg in 12.04 (which now doesn't 
have all the redundant kernels listed).

If you have questions about this then ask before doing anything as 
suggested above, OK? :-)
