Installation • After installing Debian on USB stick, stick does not boot on MacBook

My goal is to install Debian to be bootable from a usb stick on a MacBook with two usb ports. To do so I booted from Debian Live flash on the first usb port. Next I used to Debian installer to install Debian on the second USB port. Installation completed with a message that Debian was successfully installed. Yet Debian does not boot from the usb where it was installed by installer.

Live system partitions:
Device: /dev/sdc1, Boot: *, Size: 3.2G, Id:0, Type: Empty
Device: /dev/sdc2, Boot: , Size: 5M, Id:ef, Type: EFI (FAT-12/16/32)

Partitions of the usb where installer installed Debian:
Device: /dev/sdd1, Boot: , Size: 99M, Id:c, Type: W95 FAT32 (LBA)
Device: /dev/sdd2, Boot: , Size: 14.5G, Id:83, Type: Linux

After booting MacBook from the Debian Live USB stick, I try to reinstall bootloader on the second USB stick with:

sudo mount /dev/sdd2 /mnt

sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys

sudo chroot /mnt

grub-install /dev/sdd
update-grub

And `grub-install /dev/sdd` returns:

Installing for x86_64-efi platform.
grub-install error: cannot find EFI directory

Any ideas how to make it boot?
