Dude, when you do this, during the Fedora Core 4 installation, make certain that you DO NOT install another boot loader. If you do, it will always wipe out the RedHat boot loader. You only need one boot loader, so you might as well just keep the one from the first installation.
However, since you already installed both operating systems, you simply need to boot Fedora, and then you need to edit grub.conf so that you have an entry which points to the kernel used to boot RedHat. I hope that you installed each OS to a separate file system partition - otherwise you simply replaced one with the other.
