Re: Secure Boot won't let boot into Debian

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.

Even if the boot loader is successfully installed, it would be a BIOS/legacy bootloader, and the UEFI firmware usually gives higher priority to EFI boot loaders, Windows Boot Manager here.

 *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,

I have seen this too on a HP laptop. The workaround was to choose to install GRUB in the "removable path" (that's what Windows do).
