• Get filesystem UUID:

sudo grub-probe {{[-t|--target]}} fs_uuid {{/boot/grub}}

• Get filesystem label:

sudo grub-probe {{[-t|--target]}} fs_label {{/boot/grub}}

• Get MBR partition type code(two hexadecimal digits):

sudo grub-probe {{[-t|--target]}} msdos_parttype {{/dev/sdX}}

sudo grub-probe {{[-t|--target]}} drive {{/boot/grub}} {{[-m|--device-map]}} {{path/to/custom_device.map}}
