Dear Maintainer,

   * What led up to the situation?

Want to enroll my own secure boot key to my Lenovo ThinkPad X280 (BIOS 1.57 from April 2025).

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Tried various ways to boot KeyTool.efi from the UEFI Setup: adding it via efibootmgr, preparing a GPT/EFI-bootable USB stick.

   * What was the outcome of this action?

KeyTool.efi launching for 2-3 seconds with random garbage characters, then the computer rebooting

   * What outcome did you expect instead?

KeyTool UI to show up as documented in the various guides.
