Before the installation, the HDD can have any information at all. It 
can be new, fresh from the factory.  It can be an old drive with a 
bootable MS Windows system.  Any information be overwritten or 
dereferenced  by steps below.  

> ... and what you want to be there after.

After the installation the drive should have Debian 10 system from 
which  the target machine can boot and work.

Required ingredients.
* Debian workstation with network connection. (In fact any Linux or Unix 
  should work.  A few details below may vary.)
* Target machine with hardware allowing a network connection.
* HDD which will work in the target machine when this process is 

This procedure is performed.  Most steps require root priviledge.  On 
the workstation use su or sudo.

The system is to be installed on a "target HDD".  Connect the target 
HDD to a Debian workstation using a ATA cable or USB-ATA adapter. To 
my understanding the machine should be unpowered when ATA is connected 
or disconnected.  USB can be hot-plugged.

Using gparted in the workstation, make these four parts on the target 
Part 1 labeled ROOT.  7 GB.  Format ext4. 
Part 2 labeled SWAP.  1 GB.  Format swap or linux-swap. 
Part 3 labeled HOME.  3.5  GB.  Format ext4. 
Part 4 labeled INSTLR.  520 MB.  Format ext4.

Mount INSTLR at /mnt/.
mount /dev/sdx4 /mnt/           # x represents the actual drive letter.  Eg. "c".

Make a grub directory. 
mkdir /mnt/grub

Install grub on the target HDD. 
grub-install  --boot-directory=/mnt/  /dev/sdx

Ref. 5.1.5. Booting from Linux using LILO or GRUB
Note the GRUB2 example stanza.

open /mnt/grub/grub.cfg with an editor.  If the following stanza is 
not present, add it. Note that we have the files at /, not at 
/boot/newinstall/ as the example.

menuentry 'CDless CD install' { 
insmod part_msdos 
insmod ext2 
set root='(hd0,msdos1)' 
linux /vmlinuz 
initrd /initrd.gz 

> 3) Which CD image are you using?


(I'd be happy to retrieve the image from a local server, 
http://mirror.it.ubc.ca/debian/dists, but did not find it there.)

Put that .iso file in /mnt/

> 2) Given that choice (para 2 or 3), where did you get the vmlinuz and 
> initrd.gz you are using?

vmlinuz and initrd.gz are in the .iso.  No need to retrieve again.

mkdir /loop 
mount -t iso9660 -o loop,ro /mnt/debian-10.6.0-i386-netinst.iso /loop 
cp /loop/initrd.gz  /mnt/ 
cp /loop/vmlinuz  /mnt/

Verify that INSTLR is organized. 
ls /mnt
debian-10.6.0-i386-netinst.iso  grub  initrd.gz  lost+found  vmlinuz


umount /mnt

Disconnect the HDD from the workstation and connect it to the target 
machine. Connect, keyboard, monitor, mouse and power cord.  Turn on 
power. The GRUB2 menu should appear.  The title of the GRUB2 stanza 
above should appear.  "CDless CD install"  Scroll to that and press 
the <Enter> key.

vmlinuz should load and execute.  Then the initrd.gz.

If there is a complaint about low memory, go to <Go back> and "Execute 
a shell". The swap part can be verified with "blkid /dev/sdy".  Note 
that y # x, x mentioned above. If the machine has only one HDD, y = "a".
Execute "swapon /dev/sdy".  Eg. "swapon /dev/sda". Exit the shell and 
continue the installation process.

After setting location and language the installer will search for the 
CD.  Ideally the .iso image should be found as you suggested.  Here 
this message appears.

"No common CD-ROM dirve was detected. ..." 

No obvious way to proceed.
