The boot order menu in the UEFI settings.

Yes.

No. That did not occur to me; I assumed it would then refuse to boot at
all. I shall try this out and get back to you.

And I don't like / don't need either GPT, LVM, or logical volumes! Four
primary partitions has always been enough for me.

How does one do that?

I wouldn't know anything about that, but from my field experience UEFI
works with far less hassle in Jessie as opposed to Wheezy.

It isn't something I saw either until my first UEFI installation media
boot- it may have been triggered by the fact that I was using 'Launch
CSM' Legacy mode so that I wouldn't have to bother with GPT/UEFI and
could use something resembling traditional BIOS and MBR.

It is in between the tasksel stage and the GRUB installation stage. A
prompt appeared telling me that I could either 'Force UEFI' for the
operating system installation, and have Jessie configured to boot from
UEFI, or not. It detected the fact that I had booted from UEFI but my
system was capable of either booting method.
