Recreate bootloader fails with 'cannot find EFI directory'












0















I setup debian 9 for a friend of mine. Now I got the laptop back and no bootable media is found on start.



I booted from the usb drive I installed from using the live mode and followed these steps: https://wiki.debian.org/GrubEFIReinstall which led me to here: https://help.ubuntu.com/community/Grub2/Installing#via_ChRoot



When I execute 12 grub-install /dev/sdb I get



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


On sdb1 I got /EFI/debian/grubx64.efi
On sdb2 I got /proc /sys /run etc.



I'm not sure if sdb1 is my boot-partition or not - I tried both skipping/executing 8 sudo mount /dev/sdXY /mnt/boot.



I used sdb2 for all other sdXY-commands.



When I execute 13 update-grub I get lots of mkdir: cannot create directory '/var/lib/os-prober/mount': No such file or directory.



How do I recreate the bootloader?
