Just look in the /boot/grub directory. You'll find a file called 
grub.conf. Probably this only contains one option for the OS installed 
last. If a file called grub.conf.bak exists as well, copy the lines from 
there. The /boot folder probably contains the images for both FC6 and 
Centos.

This works if you choose the same boot partition for boot installations 
(a small 100MB dedicated /boot partition is more than enough) and if you 
use the /boot partition without clearing when you do the second 
installation.

Please note that the paths in grub.conf are relative to /boot, not to /

Good luck.
