I try to install FC5 on my system as a dual-bbot with WinXP Pro
(already installed) and get the error on boot up:

Booting 'Fedora Core (2.6.15-1.2054_FC5)'
root (hd2,0)
filesystem type is fat, partition type 0xc
Kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/sdb1 rhgb quiet
Error 15: File not found

When I change /boot/grub/menu.1st to say (hd2,1) or (hd2,2) I get the
error
Error 22: No such partition

Here's how I have it set up:

IDE drive 1 (/dev/hda) is just a spare data drive.
SATA drive 1 (/dev/sba) has my WinXP install (which I can boot into
using the grub boot menu just fine.)
SATA drive 2 (/dev/sdb) has the partitions in the following order:
/boot (swap) /

I tried booting up in "linux rescue" and doing a "grub-install
/dev/hda" and sda and sdb, all three, and each one gives me positive
feedback and shows my "map" file contents seemingly OK, but I still
can't boot.

Here's my /boot/grub/grub.conf

default=0
timeout=5
Splashimage=(hd2,0) /grub/splashimage.xpm.gz
hiddenmenu
title Fedora Core (2.6.15-1.2054_FC5)
root (hd2,0)
kernel /vmlinux-2.6.15-1.2054_FC5 ro root=/dev/sdb1 rhgd quiet
initrd /initrd-2.6.15-1.2054_FC5.img
title WinXP
rootnoverify (hd0,0)
chainloader +1


It doesn't make sense to me.
Those kernel and initrd files are found in my /boot partition which
should be (hd2,0), no?

Any ideas?
Thanks!
