Grub boot loader - Fedora + Server 2K3 (Help)

[BurntToast]

I'm a 100% linux n00b.

I have one hard drive. partition 1 = server 2k3, partition 2 = fedora, partition 3 = fedora swap

I installed fedora after server 2k3. fedora now loads w/o any sort of boot loader. Yet grub is in the root and it looks like its installed.

now how do i edit grub so that it knows that server 2k3 is there and to give me the option to boot to which every os i want?

I have no idea what im doing, so please take the long route when explaining things
