First, thanks to all who responded to my earler message about this issue.
Your comments, suggestions and recommendations were much appreciated.
Several of you made reference to the contents of the computer . The
motherboard is a Gigabyte B850M with an AMD Ryzen 59600 6-core processor,
both purchased and installed in September 2026. It is yet to have anything
in it. Memory size 32768MB.
The BIOS has six sections. Favourites, Tweakers, Settings, System Info,
Boot and Save&Exit. In the Boot section there is indeed a 'Secure Boot
Mode' which I disabled. When I was ready to 'Save and Exit' the 'Secure
Boot Mode' changed to 'Boot override'. The colour changed to orange from
white. The result? After 'saving and exiting', a return to the BIOS.
The one difference in the BIOS that I found is under the Settings sections
in USB configuration 'Genetic STORAGE DEVICE 0569... CD-ROM'. A footnote
reads 'Optical drives are emulated (?) as CDROM.
What would any of you suggest that I do next?

Please identify which Debian installation media you are using. If you
made your own, please provide the details -- source URL, ISO file
downloaded, checksum verification, PGP verification, burn command, and
burn checksum verification.
Please confirm this is your motherboard:

Please confirm this is your processor:

To be complete, please identify your memory module(s) and SSD/ hard disk
drive.
Regarding Setup/ BIOS/ UEFI, I prefer to "Reset to factory defaults",
reboot, enter Setup again, photograph every screen, exit, and try to
install the OS. It is possible that one or more settings must be
changed to install Debian. Figuring out which settings(s) and what
value(s) can be non-trivial.
Use a second computer to type detailed notes, save photographs, etc.,
into while you work on the first computer.
A tripod and a good digital camera can save a lot of typing. A camera
that also does video is useful for capturing error messages that scroll
by quickly.
When you have only one or two computers, keeping your system
administration notes on a USB flash drive can work ("sneaker net"). I
have multiple computers and find a networked version control system
(CVS) to be a better solution.
