Hello, I encountered the same issue : I am unable to install Debian 11 Bullseye on a Fujitsu Lifebook U7511 laptop with the debian-11.1.0-amd64-netinst.iso.
When I try to boot, I have the exactly same error : set_second_stage() failed: Invalid Parameter Something has gone seriously wrong: shim_init() failed: Invalid Parameter I can't do anything, and the laptop shutdown a few seconds after. I've tried to disable SecureBoot without any result (same error). Is there any workaround to be able to install Debian Bullseye on that laptop ? Thanks in advance for any tips ! Best regards,
