    9.1: Install grub 2.x for secure boot

    Hello,

    I used the following steps to install grub 2.0 under knoppix 9.1

    Code:
    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 after boot I got the red sign which alerts that some files are not signed.
    Can you please advise what is missing in my steps ?

    I found the following link:

    I wonder if I need this complicated procedure with knoppix.

    Thank you,
    Zvika

    Hello,

    Thanks to the huge help I got in the grub mail list, grub is now booting under secure boot.

    I had 2 problems:

    1. The shim packages I had are for i386 not amd64. So I installed the right shim packages.

    2. I had to run grub-install under knoppix 9.1 which was booted in secure boot=enable in BIOS.
    Till I did it, I got the following warning:

    Quote:
    grub-install: warning: EFI variables are not supported on this system.

    Thank you,
    Zvika

    Hello,

    According to the following link:
    https://www.youtube.com/watch?v=6JhMSKvf6Kw
    The "EFI variables are not supported on this system" can be fixed by running:

    modprobe efivarfs
    mount -t efivarfs efivarfs /sys/firmware/efi/efivars

    According to few links I found, the cause is that Knoppinx (in my case) is booting from USB stick.
    I think (not sure) this is a BUG.

    Thank you,
    Zvika
