You mention the GAG loader and at least a Dapper and Kubuntu install 
so I will assume you want a GRUB for each Linux OS right?

If you can boot into Dapper (let's say it's /dev/hdb6), run this:

grub-install /dev/hdb6

If you can't boot Dapper then boot Kubuntu and mount Dapper somewhere:

mount /dev/hdb6 /mnt/dapper
grub-install /dev/hdb6 --root-directory=/mnt/dapper

The --root-directory option is for grub to find the correct files in 
boot/grub/*. The default is to look in / which is obviously wrong if 
you are running one OS and installing grub for a different one.

Hope that all makes sense...
