MBR missing / Fedora Core 2

Hi there..

I'm feeling pretty stupid but have to post this..:)

Recently got a new server up and running with Fedora Core 2.  It's a P4-2.8HT with a pair of SATA drives running hardware RAID1

It was working fine, however the Fedora installation didn't have GRUB installed so I thought I would install it.  Somewhere along the lines I messed up and Grub wouldn't boot properly.

So, I figured I'd start over and find my mistakes so did a FDISK /MBR from a DOS boot disk. Now, the server won't boot up..

I can go in via linux rescue mode and see everything, just can't boot...

What  do I do? :)

Boot from your cdrom. Then issue the commands
chroot /mnt/sysimage
grub-install /dev/hda

OK.. got bootloader reinstalled but now getting

Booting "Fedora Core 2.6.8-1.521smp

root (hd0,0)
Filesystem type is ext2fs,partition type 0x83
kernel /boot/vmlinuz-2.6.8-1.521smp ro root=LABEL=/

Error 15: File not found

Press any key to continue


What now?  I've verifed that the filename is correct.  Is my hd0,0 incorrect?  

When I boot off the recovery disk and chroot /mnt/sysimage... I check device.map and have:

(fd0) /dev/fd0
(hd0) /dev/hde
(hd1) /dev/hdg

There are two SATA drives in this server running hardware RAID1

My grub.conf:

default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title Fedora Core (2.6.8-1.521)
root (hd0,0)
kernel /boot/vmlinuz-2.6.8.-1.521smp ro root=LABEL=/
initrd /boot/initd-2.6.8-1.521smp.img

Any input would be appreciated..:)

Problem resolved.  Changed hd0,0 to hd0,2 (forgot all about numbering starting at 0 even though it was staring right at me)...hehee..

Thanks.
