I am trying to install Debian 11 Bullseye on a Fujitsu U7511 laptop to replace a Linux Mint 20.2 installation (I wanted to try Cinnamon, but I don't like it and prefer to go back to KDE).
So, I've downloaded the debian-11.1.0-amd64-netinst.iso iso file, checked the SHA512 sum, and written it to a USB key.
When I boot on the USB key, I get this error :
Code: Select all
set_second_stage() failed: Invalid Parameter
Something has gone seriously wrong: shim_init() failed: Invalid Parameter
I've tried to disable SecureBoot in the BIOS without any result (same error).
What is causing that error ? What can I do ?
Thanks in advance for your tips !
Regards,
