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 thing but I have not been able to make it work 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) !!!
It looks like that grun check in the mbr !!!!
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.
