Right, OK. Did the installer say it was booting in UEFI mode? It says
so prominently on the first bootloader screen. If so, then you clearly
don't have a Secure Boot problem if the installer worked.
Alternatively, you may have booted the installer in BIOS/CSM mode, in
which case it might install but fail to install a boot loader at the
end of the process. *Or* you have installed in UEFI mode, but the
firmware on your computer is just ignoring the Debian-installed boot
option. That's always possible on some bad UEFI implementations,

The BIOS setup menus, if that's clearer.
Another option would be to boot the installer again in rescue mode and
have a look at what partitions you have, and what bootloader(s) you
can find on /boot/efi for a UEFI system.
