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.
