grub

[Patrick Dupre]

Hello,

I have 2 systems (identical) on 2 different disks:
THis is my /etc/grub.conf
boot=/dev/sda
title Fedora (2.6.23.17-88.fc7)
         root (hd0,7)
         kernel /boot/vmlinuz-2.6.23.17-88.fc7 ro root=/dev/sda8 rhgb quiet 
selinux=0
         initrd /boot/initrd-2.6.23.17-88.fc7.img

title Fedora (2.6.23.17-88.fc7 new)
         root (hd1,4)
         kernel /boot/vmlinuz-2.6.23.17-88.fc7 ro root=/dev/sdb5 rhgb quiet 
selinux=0
         initrd /boot/initrd-2.6.23.17-88.fc7.img


I can easily boot on /dev/sda8, but not on /dev/sdb5, However, if I do:

         root (hd0,7)
         kernel /boot/vmlinuz-2.6.23.17-88.fc7 ro root=/dev/sdb5 rhgb quiet 
selinux=0
         initrd /boot/initrd-2.6.23.17-88.fc7.img

then I can boot on /dev/sdb5

I try plenty of things but I have not been able to make it works properly.
When I try to make a grub-install from /dev/sdb5, I get:
Probing devices to guess BIOS drives. This may take a long time.
The file /boot/grub/stage1 not read correctly.

I check the /boot/grub/device.map (it has both! hd0 and hd1).

Still from /dev/sdb5,
If I do: grub
then: root (hd1,4)
I get:
  Filesystem type is ext2fs, partition type 0x83

find /boot/grub/stage1
gives: (hd0,7) !!!

Same if I do:
find /boot/vmlinuz-2.6.23.14-64.fc7

It only find the one on sda8 and never the one on sdb5
It does the same from both systems (loading from sda8 or sdb5)

I check both kernels are identical and at the right place.

then:
setup (hd0)
gives:
  Checking if "/boot/grub/stage1" exists... no
  Checking if "/grub/stage1" exists... no

Error 2: Bad file or directory type


How can I fix this grub configuration ?

thank.
