Re-installing GRUB on FC3

Hello,
I have a dual-boot system at home. I needed to re-install XP and it, as
expected, nuked the GRUB install that was put there when I installed FC3.
This is an IDE-only system with hda and hdc being DVD drives. hde and
hdg are my hard drives. The boot partition is hdg1 and the root
partition is LVM on /dev/VolGroup00/root. XP is hde1.
When I try "grub-install --root-directory=/boot /dev/hde" from the
command line as root and reboot, I get the following:
==============================
GRUB Loading stage1.5.
GRUB loading, please wait...
Error 5
==============================
If I boot from my GRUB boot floppy, then load the config file on my
/boot partition ("configfile (hd1,0)/grub/grub.conf"), everything works
fine. I've tried various combinations of grub-install from the command
line and install and setup from the GRUB shell after booting from the
floppy, but the result is always as above.
Here's the device.map:
(fd0) /dev/fd0
(hd0) /dev/hde
(hd1) /dev/hdg
Here's the grub.conf (with comments stripped):
default=0
timeout=5
title Fedora Core (2.6.9-1.681_FC3)
root (hd1,0)
kernel /vmlinuz-2.6.9-1.681_FC3 ro root=/dev/VolGroup00/root
initrd /initrd=2.6.9-1.681_FC3.img
title WinXP
rootnoverify (hd0,0)
chainloader +1
I know the GRUB can be installed and works fine (since it did after the
FC3 install), but I have yet to find the magic combination that'll work
now. Any suggestions for how to get this to run so I don't have to keep
booting from floppy?
Thanks,
pete
