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

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 rhgbquiet 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 !!
