In order to theoretically make this system boot from a
usb port, one must go in to BIOS settings and disable secureboot
then change the boot sequence order such that the first boot
device is usb/CDROM/floppy followed by the inturnal hard drive.
We did all that and, when you do that, the system puts
out a code that you enter on next boot, okaying the change.
A friend and I did all that and it still works booting
Windows, but I want to boot debian in order to mount the hard
drive and make a clone to another usb-mounted 1 TB drive because
I deleted some files I'd like to get back and better safe than
sorry. Fortunately, the drive only had 60 GB out of 1 TB used
and the Recycle Bin had not been emptied so it's possible I
should get back the 2 or 3 files I really want, the rest being
expendable but a clone drive to play with is better than playing
with the internal drive.
Here is the iso image I got to boot Debian:
debian-live-10.2.0-amd64-mate.iso
The iso image is about 2.5 GB and I have tried both a 4
and an 8 GB thumb drive, using the command
sudo dd if=debian-live-10.2.0-amd64-mate.iso of=/dev/sde
Of course the OF= command will vary depending on how many drives
are connected to your PC.
When starting from power off, the system blows by the usb
boot drive like it wasn't there. End of story.
The system otherwise still works as before. I did try a
bootable CDROM and heard a slight convulsion of activity in the
CDR drive but then realized it was a 32-bit version so of course
it didn't boot.
Any other ideas as to how I can get this project off of
high center? It might be interesting to try an old-school CDROM
of any of the recent debian versions if I can find an image that
fits on a 650-MB disk as I don't have any writable DVD's and am
not sure if any of the drives I have can burn a DVD. The image
would also need to be for AMD64.
Any constructive suggestions are much appreciated.

I have found two Linux images that boot in UEFI Secure Boot on recent
Dell machines:
debian-10.2.0-amd64-xfce-CD-1.iso
clonezilla-live-2.6.4-10-amd64.zip
Both require adjusting the Setup boot order.
The Debian installer image has Busybox, parted, fdisk, dd, and not much
more (notably gzip, ssh, and sshd). You should be able to connect an
external USB HDD, mount it, and dd the system drive to the USB drive.
The Clonezilla image is customized Debian live in a big FAT32 UEFI
System partition with room to spare. I used my desktop to add a folder
and my homebrew imaging script. When booted, I start a shell rather
than Clonezilla, mount an external USB HDD or network share, and have at it.
I tried switching the machines from UEFI mode to Legacy mode via CMOS
Setup, but it did not work. I discovered that if I press F12 for a boot
menu during POST, there are options to change between Legacy, UEFI,
and/or Secure Boot. These work. Perhaps your machine has something
similar.
As a last resort, perhaps you can remove the system drive and put it
into a Debian machine (with adapters and interfaces as required).
