IIRC the main question is whether your Grub comes with support for USB storage.
If it doesn't you're out of luck.
If it does, it should be a small matter of typing

set root=,
linux /
initrd /

where those things can be completed with the help of TAB completion.

But it may depend on what exactly you're booting from that disk, which
may require specific arguments to be passed to the kernel.

Ah, the old Thinkpads. Swapping out the HD always just one screw away.

I'll miss my old X230 (one of the last capable of this trick) which is
in process of being replaced with a sleek and snobby X260. OTOH, the old
one is promised to a nice person who's in need of one.

Note: debian-cd and debian-live build scripts are different.

Debian-live are not provided via jigdo but just as single bootable images.
Debian-live for i386 is almost unusable given the amount of memory it takes
to boot up a live CD image well and to load all running components into
memory.

As far as possible, the image testing team no longer spend huge amounts
of time on 32 bit Debian live images.

According to :

So, the Sony laptop has Debian 9.13 i386 installed on the HDD/SSD?


Debian 9 LTS support ended on 01 Jul 2022:

https://endoflife.date/debian


If the Sony laptop can boot Debian 11 amd64 via CD, it should be able to 
boot an amd64 OS via USB.  I suggest copying 
debian-12.5.0-amd64-netinst.iso to a USB flash drive and trying to boot 
it.  If it works, you can decide if you want to use d-i, if you want to 
burn a live distribution to a USB device, and/or if you want to install

Before you spend too much time on this, do be aware that Debian is
dropping i686 as an install architecture. There won't be installers
for i686 in future releases of Debian. You will only be able to run
i686 packages as a foreign arch on a machine booted with an amd64

Building your own live images for amd64 and other supported

We are glad to help.  :-)


On Debian GNU/Linux, SATA drives (internal and external) should have 
special files (device nodes) under /dev.  You can use the ls(1) command 
and a glob pattern to find them:


~ # ls /dev/sd?

/dev/sda


You can use the fdisk(8) command to list the partitions on a drive.  For 
example, here is the drive containing Debian in the computer I am using now:


~ # fdisk -l /dev/sda
Disk /dev/sda: 55.9 GiB, 60022480896 bytes, 117231408 sectors
Disk model: INTEL SSDSC2CW06
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x544032f5

Device BootStart   End  Sectors  Size Id Type
/dev/sda1  *2048   1953791  1951744  953M 83 Linux
/dev/sda21953792   3907583  1953792  954M 83 Linux
/dev/sda33907584  29298687 25391104 12.1G 83 Linux
/dev/sda4   29298688 117229567 87930880 41.9G 83 Linux


Partitions can contain one of several things.  One possibility is a file 
system.  I keep detailed records on all of my OS's and drives, so I know 
what is what.  Figuring out the contents of an unknown drive using the 
Debian rescue shell is possible, but requires more knowledge and effort. 
 Using a live Linux distribution instead of the Debian rescue shell can 
make such tasks easier.  I install Debian onto a SATA SSD via a USB-SATA 
adapter cable for this purpose.



Once you have identified the device node of a partition that contains 
the file system that you want to read and/or write, you must mount the 
file system.  The first step is to create a mount point with mkdir(1):


~ # mkdir /scratch


The second step is to mount the file system with mount(8):

~ # mount /dev/sda4 /scratch


Repeat the above process to mount any additional file systems that you 
want to read and/or write.



One the file system(s) are mounted, you can read and/or write files 
and/or directories.  For example, you can use cp(1) to copy files from 
an internal drive to an external drive.

As far as I know, you have dmesg in the rescue shell. So the way to
go would be:

- insert your external disc
- wait a second or two for things to settle
- issue "dmesg | tail"
- you'll see your kernel recognising external media and trying
  to make sense of it. Here's an example:

This was me inserting a DOS partitioned stick with one primary partition
(sdb1). Therefore, the block device will appear as /dev/sdb1.

Your mileage will almost certainly vary.

Now you can, e.g. say

mount /dev/sdb1 /mnt

The kernel will try to auto-detect which file system is on your partition.
You can, of course, choose another mount point than /mnt -- it has just
to be some directory. Its contents, if any, will be shadowed by your new
file system and won't be accessible as long as the mount is in effect.

From here on you can use mv, cp, whatever. Whenever copying lots of stuff
recursively, the option "-a" to cp comes in handy.

> There is nothing under media nor root; under usr I can see only: bin lib

Your rescue system is very bare-bones: it won't do automounting for you,
etc. I think that makes sense.

I hope the above description gets you started. In case of doubt, just

Things mounted by the system would probably show up under /media or /mnt .


Where are the internal h-drive and the external?


To mount those you need the device names.  Perhaps you'd be better off with
a graphical file manager.

Thanks Eben and David!
I am now on a shell (BusyBox v.35.0 Debian 1:1.35.0-4+b3)
I don't see the mounting points to execute cp.
There is nothing under media nor root; under usr I can see only: bin lib
local sbin share.
Where are the internal h-drive and the external?
I would very much appreciate your further help.

Yes.



Furthermore, the ultimate question is how could I copy folders from the
computer's hard drive to the external one while in rescue mode?
Many thanks!!

This is how I start a rescue shell using debian-11.9.0-amd64-netboot media:

Debian GNU/Linux installer menu (BIOS mode) -> Advanced options
Advanced options -> Rescue mode
Language -> C
Continent or region -> North America
Country, territory or area -> United States
Keymap -> American English
Hostname -> debianrescue
Domain name -> tracy.holgerdanske.com
Select your time zone -> Pacific
Passphrase for /dev/sda3 ->  -> Continue
Device to use as a root file system -> Do not use a root file system
Rescue operations -> Execute a shell in the installer environment
Executing a shell -> Continue


Once busybox(1) is running, you can issue mount(8) and cp(1) commands 
similar to using a shell.

Is your computer's hard drive is already mounted?  Are you comfortable in a
shell?

Dear all:
Is it possible to mount an external hard drive while running Debian in
rescue mode?
Furthermore, the ultimate question is how could I copy folders from the
computer's hard drive to the external one while in rescue mode?
Many thanks!!
