grub is typically installed in /boot, and the efi directory is
typically mounted at /boot/efi, which is where UEFI firmware looks for
the EFI executable to load.
Following the same pattern, if grub is being installed in media/sdb1,
the efi directory would be /media/sdb1/efi.
I don't know if this
Hi Randy,
My goal is to install grub2 in sdb1 that will work when secured boot
is enabled.
I don't have any restrictions on the files tree in /dev/sdb1.
Can you please tell me what sequence I should use ?
Especially the grub-install parameters.
I'm running the installation under knoppix 9.1

Hello,

I did the following steps under knoppix 9.1 :

apt-get install grub-efi-amd64-signed

Hi Randy,
Thank you for your reply.
Did you mean that the grub-install should be:
grub-install --boot-directory=/media/sdb1/boot
--efi-directory=/media/sdb1/boot --uefi-secure-boot ?
This way, /media/sdb1 contains only the boot directory.
boot directory contains 'ÉFI' and 'grub'
After this
Hi Pascal,
Thank you for your reply.
shim-signed is installed. The output of:
apt list --installed | grep shim
is:
shim-helpers-i386-signed/stable,testing,unstable,now 1+15.7+1 i386
[installed,automatic]
shim-signed-common/stable,stable,testing,testing,unstable,unstable,now
1.39+15.7-1 all
If the boot directory is /media/sdb1/boot, it seems odd for the efi
directory to be the parent directory, rather than
/media/sdb1/boot/efi.
