If you have one distribution installed with a bootable OS from Grub, you just need to install the second Linux distro to a different partition and modify your menu.lst (grub.conf in Fedora) file in the /boot/grub/ directory. In order to get the information you need to make this entry you will have to mount the 2nd distro so you can find the initrd and vmlinuz file names.

If you have a distribution installed and have partitions set up post the output of "fdisk -l" (Lower case letter L) to get more specific advice.

If you do it that way every time the second distro gets a kernel update you will need to edit the grub file again.If you use the " rootnoverify " you wont need to do that ,but will will see grub again when you boot the second distro.I have 3 versions of linux on 1 hd and vista on another here is what Fedora's( thats the grub that runs my linux drive)/boot/grub/grub.conf file looks like...

title Fedora (2.6.23.1-42.fc
root (hd0,0)
kernel /vmlinuz-2.6.23.1-42.fc8 ro root=LABEL=/12 rhgb quiet
initrd /initrd-2.6.23.1-42.fc8.img
title Vista
rootnoverify (hd1,0)
chainloader +1
title Sabayon
rootnoverify (hd0,4)
chainloader +1
title Ubuntu
rootnoverify (hd0,5)
chainloader +1

You just need to know where you put the other linuxs...

I forgot to tell you, when you install the second linux,put it's grub in the root Partition.
