Thanks for the quick response. And I am sorry for the confusion. Let
me make it clearer.

On current hda there is a debian installation B, and it already saw
the debian installation A which was on old hda1(new hdb1). Current
grub is the grub on debian installation B on current hda.

So I guess I do not need to touch any grub conf file in the debian
installation A. right?

Currently I have undone the change in mtab. fstab is fixed. still
having the error.
