BIOS showed the NVMe SSD.

Pressing F3 during boot opened the "Insyde File Explorer", which let me select the debian shim.efi file that booted grub.

Boot from live-usb

After booting from live USB once and updating the laptop's firmware, it would not boot from usb anymore. I had to unplug the USB-A expansion card and replug it - then it could boot from there again.

Re-installing grub

Boot from the kernel with F3 by manually selecting the shim.efi, then run "update-grub2" to install the bootloader into the UEFI mainboard settings.

linux kernel boot issue

Falsche Shim-Signatur (bad shim signature)

• 6.16 did not boot, brought shim error
• 6.12.xx did boot

Reason: I had manually installed 6.16 to get Debian running on the laptop, see https://community.frame.work/t/tracking-debian-testing-on-the-framework-laptop/14448/34 This kernel had no signature.

This time I wanted to keep secure boot enabled. 6.16 is old, to instead of signing it with my own secure boot key (see https://wiki.debian.org/SecureBoot) I decided to install a newer official kernel.

Manually install Debian backports kernel
