Hello,
My original grub.conf uses hd0,5 as device and /dev/VolGroup00/LogVol00
as root.
The grub command "setup (hd0)" doesn't work.
When I run "/sbin/grub-install hd0,5" or "/sbin/grub-install
/dev/VolGroup00/LogVol00", the return is "The file /boot/grub/stage1 not
read correctly". And the floppy disk led turns on and I hear the head moving.
I haven't seen the earlier part of this thread, so maybe I've missed
something, but hd0,5 looks like a logical partition inside the extended
partition and /dev/VolGroup00/LogVol00 is an LVM logical volume. I'm
pretty sure that grub needs to live in the MBR or the boot record of a
primary partition. I've been told that recent grubs can have /boot be a
logical partition, but have not verified that. grub cannot live in or
boot from an LVM volume. The root file system (not /boot) can be a
logical volume.
I have /boot as a small primary partition (/dev/hda3 or (hd0,2)). Grub
itself is installed in the boot record of that partition, which I made the
active boot partition using fdisk. My / filesystem is in
/dev/VolGroup00/LogVol00. Thus the grub stanza reads
title Fedora Core (2.6.17-1.2187_FC5)
root (hd0,2)
kernel /vmlinuz-2.6.17-1.2187_FC5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.17-1.2187_FC5.img
I haven't had to do it by hand, but I think that would be
grub-install /dev/hda3
or
grub-install (hd0,2)
with no options. There's a comment in grub.conf to the effect that,
because I have a /boot partition, all paths are relative to /boot.
Thanks for your time,
Vinicius.
