Blocked by the current security policy

Hi,

After a regular update of my 18.04 installation on a Lenovo Yoga 720 I was suddenly greeted at boot with an error saying Ubuntu has been blocked by the current security policy. I've used ours to trouble shoot, including using boot-repair both in automatic and advanced mode with different settings, plus attempted to do it manually and attempted to install rEFInd without succcess. I desperately need help to restore my system and hope someone may be able to help based on the boot-repair output to pastebin:

Thanks,

Lars

Problem solved. My solution was to make a new small partition before the uefi-partition. With boot-repair, I was able to install Grub2 on that partition. I hope it keeps working. I need a few updates and reboots over the coming weeks to trust my system...
