Start by verifying you're running UEFI still. One update might have disrupted that. If confirmed, add the following to your grub.cfg: under 'System setup' include 'menuentry_id_option' 'uefi-firmware' with 'fwsetup'. After saving, reboot and the option should show up. Let me know if it works! ~Breadpudding Edit: Found this in my Debian grub.cfg; compatibility could differ with Mint. Edited July 19, 2019 by Breadpudding Added an extra note
