Some people post pictures to appropriate sites when it's not possible
to copy the text (eg, in the BIOS, running Grub, etc.) but most of
my questions can be answered with files that are still readable after
the system is up and running. They should be transferrable to a system
running an email client.

Fair enough. That's why I'm posting examples of methods that work,
which might help in your understanding.

I think that giving this reference confirms that you are using "GPT"
to refer to two completely different things: the partitioning of the
disk, and the UEFI method of booting. This is confusing.
The OP has described a problem with a ~2006 laptop which, as far as
I can understand it, involves GPT devices (as well as MBR ones),
and *BIOS* booting.
Cheers,
David.
