I don't have the paid version of Macrium, I use the free one.
Is this what you refer to?:
Assuming you have the paid version , you need to enable the boot menu before you can use it.
From a quick look at the website, it seems you d/l the WinPe recovery environment.
That is then added to the Windows boot menu like this: Windows Boot Menu
You can also make a WinPE boot disc from that download, in addition to the options for the Linux and Bartpe boot cd options you get with the free version.
Macrium offers that instead of a separate bootable partition.
I mainly use Paragon Drive Backup 10 Server Edititon.
That gives the options of Linux/Dos, and WinPe boot cd's , as well as the ability to create a Ramdisk boot entry ( similar to the Macrium method).
It also has the option to create a separate bootable partition/ HD , and it is also possible to create a dvd /blu ray/flash from which you can boot and restore the image it contains.
It is even possble to install a windows o/s, put whatever updates and programs you want on it, create a bootable dvd/blu ray/flash drive , and use that instead of the windows installation dvd to install on different machines.
Hope it helps.
