The Critical partitions on a UEFI system are the Recovery, EFI System, MSR and OS. An imaging utility will back these up if it understands UEFI installs.
You can use the Windows built in utility or a third party imaging software. Some other folks will probably have recommendations. I use the Windows one, but it is fairly limited as far as options.
It makes copies while the system is active. You have to create the backup image on a separate hard drive from the one being imaged. I like to keep an internal drive for this purpose, but external ones can be used as well.
