So, how can I proceed with a brand new drive,

Don't know why no one's mentioned this, but... you could always just
install an actual bootloader on the drive that boots from the device
from which you really want to boot. (I think you can do this with grub...)
Of course, plugging that drive into any other computer might make for an
interesting experience :-).
I am sorry - but ...
the design and implementation of the traditional
(msdos) scheme and ( from what I understand so far
from all the respondents), even gpt, effectively render
the disk to have a signature which BIOS interprets
as a valid partition table AND as bootable, and thus
hangs there looking for what does not exist.
Why the design mixed 2 different things into 1, I have
no idea. But AFAIAC, it sucks and blows atthe same time.
Well, MBR stands for master boot record. It stands to reason, in the
epoch in which it and BIOS were invented, that you'd only use MBR if
you want to boot a system.
Once computers and drives got cheap enough, and in particular drives
got big enough, is when the mortal user with a budget usurped MBR to
do only partitioning.
So, let me ask a simple question.
Technically (I mean programatically), how difficult is it to
fix both BIOS and fdisk so that unless a partition is marked
as bootable, the partition table will not contain the boot signature
and BIOS will still accept the partitioning scheme, but
move on to the next drive in the boot order?
Thanx.
