Actually a later version of UEFI solved the problem again - I am currently running 2.37 and kernel boots properly with secure boot disabled.
However, even after intense web research I didn't find a way to update the UEFI without Windows. So in case you have no Windows any more you have to download a Windows trial image and create a Windows start DVD just for UEFI/BIOS updates. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1717657 Title: Boot hangs when loading initial ramdisk Status in linux package in Ubuntu: Invalid Bug description: Kernel 4.13.2 fails to boot.
