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
The thing you have to remember is that the "root (hdx,x)" option is
a Grub option, not a kernel option. It tells Grub where to find the
kernel and initrd files. If there are both in /dev/sda8, then you
need to use root (hd0,7) for both. If the kernel and initrd for the
new install of f7 are in /dev/sdb5, then you can use root (hd1,4).

Hi Mikkel,
I am not sure about what you said.
Even not saying root (), grub should find the image if device.map is
correct ?
Anyway, I tried what you said by setting root (hd1,4), but stil it does
only find the image on hd0,7 !!
