I edited the note, adding the highlighted words:
NoteOn some UEFI based computers booting to Macrium Rescue fails if Secure Boot is enabled. If you can't boot to Macrium Rescue and have Secure Boot enabled, press ESC on Recovery screen to enter UEFI settings and disable Secure Boot.
You can enable it again when boot issues have been fixed.
In my case, with an Asus laptop and a Medion tablet I can't boot them to Macrium Rescue (default Macrium PE created by latest version of Macrium Reflect Free) if and when Secure Boot is enabled.
Both laptop and tablet are running clean installed W10 PRO Build 16199, new rescue media created after installation separately for both (laptop x64, tablet x86).
The same applies to Generation 2 Hyper-V virtual machines, Secure Boot must be disabled in order to be able to boot to Macrium Rescue. Of course with Checkpoints and VM export function there's no need to make system images of Hyper-V virtual machines but as Macrium is the best possible way to fix even the VM boot issues it is good to know how to boot with rescue media if VM does not boot anymore..
