You probably just needed to select in the "BIOS" (actually the UEFI) to
boot from the external disk. There is usually a key that triggers that
menu. On some laptops, it is not a key on the keyboard.

No, it has to be mounted under boot, that is, at /boot/efi, which can
not be a directory, but a mount.
Of course, disk must be GPT.
All this should have been done automatically by the installer.
