OK....the root partition for Fedora *used* to be /dev/sda2 and now is
/dev/sdb2.  This is seen here:

I have changed /etc/grub.conf manually to be:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,1)
#          kernel /boot/vmlinuz-version ro root=/dev/sda2
#          initrd /boot/initrd-version.img
#boot=/dev/sda2

        module /boot/initrd-2.6.21-2950.fc8xen.img

Where all (hd0,1) were changed to (hd1,1).

What else needs to be done?

Thanks.
