I remember to have seen discussions about newly installed shim adding names of older shims or bootloaders to something called SBAT. I find in my mailbox a mail with a link to https://bugzilla.opensuse.org/show_bug.cgi?id=1209985 About SBAT i found in the web: https://www.gnu.org/software/grub/manual/grub/html_node/Secure-Boot-Advanced-Targeting.html https://github.com/rhboot/shim/blob/main/SBAT.md Have a nice day :) Thomas
