Same problem is on v18 MR-1-Build396, after fresh install is EFI partition empty.
I tried to install a new grub from Ubuntu Live 20.04, but ending with error "kernel doesn`t support EFI handover".The problem was a new grub on Ubuntu.After installing the EFI loader from Ubuntu18.04 it already works fine.
Solution:
1) Install SFOS
2) Boot from USB Flash Ubuntu Live 18.04
3) Open terminal and write:
sudo apt install grub-efi-amd64-bin sudo mount /dev/sda1 /boot sudo mkdir /boot/efi sudo mount /dev/sda2 /boot/efi sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi/
That seems to be the Sophos MO, over-promise and under-deliver. I think they confused the two, but I've been watching this since v16 now and it is always the same.
As some of you may have seen, unfortunately the work-in-progress release post for MR3 was accidentally published in error. The post has since been removed. Note that the information contained in the post may be incorrect as the team is still actively working on the release.
SFOS v18 MR3 is still expected to be launched next week, so please stay tuned.
