Edit the /etc/grub.conf file of whichever system you installed last to 
include boot records for both systems.

Boot to whichever one currently works.

Mount the file system for the other system and open 
/mnt/otherfilesystem/etc/grub.conf in an editor for reading.

As root, edit /etc/grub.conf for the system that is running, and add 
into that file the specific lines for the other system.  For example, my 
grub.conf looks like:
=================================
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,0)
#          kernel /boot/vmlinuz-version ro root=/dev/hda1
#          initrd /boot/initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title Fedora Core 2 (2.6.5-1.358)
	root (hd0,0)
	kernel /boot/vmlinuz-2.6.5-1.358 ro root=LABEL=/123 rhgb quiet
	initrd /boot/initrd-2.6.5-1.358.img
title Fedora Core 1 (2.4.22-1.2188.nptl)
	root (hd0,1)
	kernel /boot/vmlinuz-2.4.22-1.2188.nptl ro root=/dev/hda2 hdc=ide-scsi 
hdd=ide-scsi ide0=ata66 idebus=66 rhgb
	initrd /boot/initrd-2.4.22-1.2188.nptl.img
==================================================

so that I can boot FC1 or FC2.  (Note, the kernel line for FC1 above may 
be wrapped and should all be on one line.

I hope this helps.
