Hello!

I tried to migrating from the first to second SATA drive My Debian
Etch OS with Gparted.

I copied the /, /usr, /var, swap, /tmp, /home partitions of the system
to the second SATA: sdb with Gparted.

Then I tried to set up grub to boot this Debian system from the first
SATA drive sda, and did the following:

- boot the install CD of the Etch Netinstall
- at prompt use expert
- ...
- detecting disks
- did not disk partition
- run a shell

Here I follow the mini howto:
http://wiki.archlinux.org/index.php/Reinstalling_GRUB

cd /
mount -t ext3 /dev/discs/disc1/part1 /mnt
# this is the / partition of the sdb
mount -t ext3 /dev/discs/disc1/part2 /mnt/usr
# this is the /usr partition of the sdb
mount -t proc proc /mnt/proc
mount -t sysfs sys /mnt/sys
mount -o bind /dev /mnt/dev
chroot /mnt /bin/bash

grub-install /dev/sda

Error: /dev/scsi/host1/bus0/target0/lun0/disc does not have any
corresponding BIOS drive.

I can't here as root to use nano because of the bterm error. I did the
following to get some editor, namely mcedit:

TERM=xterm
export TERM
mcedit /etc/fstab

I can to use here mcedit, but with difficulties. Still can to edit
fstab, however.

But, I can't to install grub to boot sdb root from the sda MBR.

Any advices will be appreciated!

is /etc/mtab correct ?

is /boot/grub/device.map (which might be created by grub-install by
reading /etc/mtab) correct ?

have you searched google

Linkname: grub error does not have any corresponding BIOS drive - Google Search

Yes, it is:
nano /etc/mtab

....
/dev/sdb1 / ext3 rw,error=remount-ro 0 0

I checked /boot/grub/device.map:
(hd0) /dev/sda
(hd1) /dev/sdb

I edited menu.lst:
# kopt=root=/dev/sdb1 ro

# groot=(hd1,0)

I run grub-install with --recheck option.

Still I have no success.

I boot the Debian Etch system from the sda, and check the /boot/grub/
directory of the Debian Etch system from the sdb. There I find strange
situation. The /boot/grub/ directory contain another /boot directory
with grub/. I removed this second boot/grub/ directory.

This must be the case because when I tried to run grub-install I tried
also to reinstall grub with aptitude reinstall grub..

I shall reboot to see how it works the grub-install now.

At last I have success!

I don't use grub-install command but run grub on the command line,
and:
grub> root (hd1,0)
grub> setup (hd0)
grub> quit

Success!!

I am not sure if I understood you correctly, so please correct me if
I am
wrong, but I assume:

* you have basically moved all needed partitions for a full Debian
system from
one disk to another,

* and now you want to install GRUB to this second disk so that GRUB
can boot
from that disk (and you can eventually remove the old disk from
the system).

Can you still (temporarily) boot from your first disk where GRUB is
still
installed? You don't need to be able to boot Debian from the old
disk, you
just need a working GRUB install there. Does GRUB display a menu when
you boot
from your old disk?

Then you can use the GRUB shell, and within the GRUB shell you can
run several
commands to install GRUB to the second, new hard disk.

You get to the GRUB shell by pressing the "c" key when GRUB displays
the menu.
(Maybe you have to press "Esc" first, I am not sure and can't try it
now.)

Let me know if this would work for you, then I could tell you more
about which
commands to run in the GRUB shell.

OK, I hadn't seen this last message from you when I wrote mine, but I
see that
you have had success with exactly what I was going to suggest to you.

I am just wondering if you are aware that you still need your first disk
installed to boot the second. So far, GRUB is not installed on the
second
disk, so if your first disk breaks, you will not (easily) be able to
boot from
the second disk. I am not sure about what you are doing with those
two disks,
but maybe it is wise to install GRUB also to the second disk, in case
you
remove the first one at some point. (Or you could directly boot from the
second disk.)

By the way, if you have a floppy drive, you can install GRUB on a
floppy, too,
then you have a GRUB emergency disk which lets you perform operation
such as
those you described (in the GRUB shell) (for cases of drive failure
etc.).

It is not, if I have understood correctly your aims.

When I have an i386 / amd64 installation on (say) sda and I want to copy
it on (say) a new disk sdb in such a way that when the new disk is
installed as sda it boots as a "clone" (but with partitions of different
size; if sda and sdb are identical I use dd) of the old sda, this is
what I do:

recreate partition table and filesystems on sdb

mount the / of the new disk as (say) /tmp/NEW/ and then the /var/ (say)
of the new disk on /tmp/NEW/var/ , and so on.

clone the contents of the filesystems (with rsync or whatever)

chroot /tmp/NEW/

and then inside the chroot I mount what i need:

mount /proc/
mount /sys/ # if needed, for example to recreate a yaird initrd
mount /dev/pts
(and so one for every "virtual" filesystem which I need. I do not use udev)

finally (still in the chroot) I edit two files:

(1) I edit /etc/mtab in such a way that it corresponds to /etc/fstab ;
so in your case it would be

/dev/sda1 / ext3 rw,error=remount-ro 0 0

(sda and not sdb). The rule is: the mtab must contain the lines that it
will contain when the system will be booted from he new disk.

(2) I edit /boot/grub/device.map ; this way the logic seems opposite to
the previous one; in your case this would be:

(hd0) /dev/sdb

This line means: the disk that grub and the bios will see as the first
one (hd0) when the system will be booted, is the disk that Linux is
seeing as hdb in the moment that grub-install is executed.

(3) I run

grub-install /dev/sdb

Note: "(hd0) /dev/sdb" versus "(hd1) /dev/sdb" changes a bit in the boot
record which is written in the MBR of sdb.

(4, optional but useful to avoid confusion) I re-edit
/boot/grub/device.map so that it will be correct onece the sistem will
be booted from the new disk ; in your case

(hd0) /dev/sda

Finally I umount the special filewistems, the (say) /var/ partition (and
so on), I exit the chroot, I umount even the / partition of the new disk.
