Well, the OP wrote:
"Previously, I've successfully installed Debian using official
installation media on this machine (also using BIOS boot
interface), so I know that it works in principle. But now I want to
do it using command line utilities like debootstrap and grub-install."
But:
"the problem is that the ESC boot menu doesn't show an entry for
(the model name of) /dev/sda, so I can't boot into it."
My first question would be whether it makes a difference to use [F2]
and enter the BIOS/CMOS, rather than [ESC] to get just the boot list.
As you could read in another thread, I have been testing the d-i
installing on a BIOS machine, using a spare partition, in order to
see how it behaves with and without a BIOS Boot partition. However,
blanking the entire internal drive on a machine just for this
exercise is pushing things a bit too far, sorry.
And I'm not sure that results from one of /my/ machines would be
particularly useful either. They are either native BIOS booters, or
have a compatibility mode that just works, without requiring anything
out of the ordinary configured for a GPT disk in BIOS mode. That might
not be true for your Asus UX31A.
At this point, my action would be to install in BIOS mode using your
two methods, conventional d-i and debootstrap, and run bootinfoscript
(from package boot-info-script) on each, to look for differences.
I would avoid doing any UEFI booting between these runs.
Cheers,
David.
