Grub disappeared after power off and eject external drive

I installed arch Linux in my external hdd with Uefi boot, and installed grub to my eps boot partition which is (/dev/sbc1) , I mount it in /mnt/boot and my eps=boot/ , I follow the arch wiki guide and this is how I install grub

After pacman grub

chroot /mnt /bin/bash

grub-install --target=x86_64-efi --efi-directory=eps --bootloader-id=grub --boot-directory=esp --debug

Then generate the grub.cfg file to the /boot

I have successfully boot into my desktop environment (gnome) but after I power off and eject the external drive, I plug in back , my GRUB is gone and I cannot boot into it unless I repeat the process of installing grub-install and generate cfg file again, what do I have to do to fix this ?
