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 !!

What I am saying is that the root directive must point to where the
kernel and initrd are on the disk. Do you have the
vmlinuz-2.6.23.17-88.fc7 kernel in the /boot directory on /dev/sdb5?

I have the same /boot directory on both disks

this is the fstab

/dev/sdb5               /               ext3    defaults        1 1

Ok - take a look in /boot on the new install. What kernels and
initrds do you have in there? Is vmlinuz-2.6.23.17-88.fc7 in that
directory, along with initrd-2.6.23.17-88.fc7.img?

Yes

There are other ways to manage this, but lets take things one step
at a time and get what you are trying here working, and you
understanding what is going on.

One other point - you should really upgrade to a newer version - F9
or F10. F7 has not been supported for 6 months, and F8 is also
unsupported now.

I will make the update, as soon as I will have understand what is going on.

That is fine - I will do my best to explain things. I hope I can
teach you what is going on. It can be confusing because the root you
tell Grub to use may be different from the root directory the kernel
uses.

Ths grub version in FC10 is almost the same as in FC7

The main difference is the pretty screen you can use instead of
seeing what is going on.
