I'm trying to install grub 2.x for secure boot . I did the following steps under knoppix 9.1 : mkfs.fat -F32 /dev/sdb1 mount -t vfat /dev/sdb1 /media/sdb1 apt-get install grub-efi-amd64-signed grub-install --boot-directory=/media/sdb1/boot --efi-directory=/media/sdb1 --uefi-secure-boot But when I selected this device in the boot menu I got the red message telling this partition contains unsecured code.
Is shim-signed installed ? What is the contents of /media/sdb1/EFI ?
