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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1717657 Title: Boot hangs when loading initial ramdisk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1717657/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
