Re: "Bug" in Debian Installer?

Perhaps at this point installer detected EFI system partition that was
used to install grub:
In the past, d-i "Install" would prompt me regarding GRUB. This time,
it did not.

When I moved the 2.5" SATA SSD to a homebrew Intel DQ67SW computer and
configured BIOS Setup:
"Boot" -> "UEFI Boot" -> "Enable"
The SSD would not boot.
New boot entry usually should be created in such case from EFI Shell, by
efibootmgr, etc. Some firmware allows to choose an .efi file
(EFI/debian/shimx64.efi) to boot. I do not remember which grub or shim
script creates EFI boot entry.
I later discovered that the first install created a directory and put
files into the Dell's ESP (!). I did not select this, nor do I desire
it. This is a defect with d-i:
Why do you think it is wrong? EFI system partition is designed to
contain boot loaders from multiple vendors. A conflict may happen due to
EFI/BOOT/bootx64.efi, but it is for removable media and for buggy
firmware (as a workaround).

-rwxr-xr-x 1 root root 84648 Mar 16 22:19 fbx64.efi
Fallback should create boot entries listed in BOOTX64.CSV if some
problem with boot is detected. I am unsure concerning changing boot
order. However this file is invoked by shimx64.efi or grubx64.efi
(loaded by shim) and I do not expect that shim is booted with no user
action when a disk is installed into another computer.

So, I agree that d-i "Install" choice has bug(s) when installing Debian
into a computer with multiple storage devices.
I do not think multiple storage devices is an issue. I suspect that you
are not happy that by default Debian installer picked existing EFI
system partition.
Were you trying to prepare a disk for another computer? Did you created
ESP on that disk and specified mount point? Anyway likely it is a reason
to enable low priority configuration questions.
