I used Clonezilla-live- 3.1.3-16-amd64. On my laptop installed two OS: windows 11 and Ubuntu.
1. I created image from partition. As a result my laptop failed to boot. I didn't do restore from image, I just created image from partition. I received this error message when I tried to boot: "verifying shim SBAT data failed: Security policy violation. Something has gone wrong: SBAT self-check failed: Security policy violation." After this error message my laptop switched off.
After that I disable Secure Boot in UEFI/BIOS. It helps. I boot successful.
To fix Secure boot issue, I boot to Ubuntu and execute these commands:
sudo apt update
sudo apt install --reinstall grub-efi-amd64-signed shim-signed
sudo grub-install
sudo update-grub
It helps. I enable Secure Boot. And my laptop boots successful.
2. I created image from whole ssd disk. As a result my laptop failed to boot again with the same error message. Disable secure boot in UEFI/BIOS helps again. To fix Secure boot issue, I again boot to Ubuntu and execute the same commands as I typed above. But it doesn't help: if I enable Secure Boot, my laptop doesn't boot with same error message.
Could you help me to fix my Secure Boot issue?
Duplicated post. Let's focus on this:
