This is my $0.02 so take it for what it is.
I had the same problem with multi-boot configuration and
thanks to others for leading me the way. Here is what
I found and it fixed my problems.
First -- the basics seems to be:
Your hardware configuration should be:
IDE0 - Primary/master - hard disk #1 = /dev/hda (boot drive - required)
IDE0 - Secondary/slave - hard disk #2 = /dev/hdb
IDE1 - Primary/master - CDROM/DVD #1 = /dev/hdc (cdrom - required if
IDE1 - Secondary/slave - ? = /dev/hdd
I have tried before all sorts of other combinations and it wreaked
havoc with the fedora installation, at least this is what it did
to me. Note that for windows OS, it does not matter as to where
the boot hard disk is installed as long as it is a primary/master
either on IDE0 or IDE1 and the cdrom/dvd can be anywhere else but
for fedora -- apparently it DOES matter. I note that if the cdrom
for fedora was on /dev/hdd -- fedora complains with a interrupt problem
and spits a message to the message file very often so when I put
the cdrom on /dev/hdc -- it "shut up"!
Once you get your hardware configuration right and your devices
are "fedora approved", you can reinstall grub with
1) Insert your fedora boot cd
2) Run 'linux rescue'
3) Do 'chroot /mnt/sysimage' stage when asked
4) grub-install /dev/hda (NOT /dev/hdaX where X are paritions)
5) remove CDROM
6) type exit twice (it will reboot)
then grub should come up.
Hope this helps,

Subject: Re-installing GRUB on FC3
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
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...
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:
Here's the grub.conf (with comments stripped):
title Fedora Core (2.6.9-1.681_FC3)
kernel /vmlinuz-2.6.9-1.681_FC3 ro root=/dev/VolGroup00/root
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?
