Hi,
every once in a while I have boot issues with my dual boot laptop where Windows 11 and Tumbleweed are installed.
Just today I booted Windows (which does not happen very often but sometimes I need to) and had to install a bunch of updates. Now I cannot boot to TW anymore. So something must have destroyed the boot. When I open the BIOS during boot I still have the entry opensuse-secureboot available but selecting it just brings me back to the same selection so apparently something is broken there.
Are there any errors or other messages when you try to start opensuse-secureboot? Does your BIOS support "boot from file"? If yes, can you try selecting \EFI\opensuse\shim.efi manually? Is \EFI\opensuse still present? What is the content? Boot any live linux, post full output of "efibootmgr -v".
What is the correct way to recover
Without understanding why it fails recovering is difficult.
that and can I avoid this somehow?
Thanks, Wolfgang
