Angels have the Phone Box
When Macrium creates the rescue media for you, it includes whatever drivers necessary for your system. The rescue media is unique to your system, and will not necessarily have the same list as shown in the tutorial. I wouldn't worry about it.
Image selected disk (all partitions) will be what you want, since Backup Windows may leave out partitions such as "OEM Recovery". Not to complicate things, but, technically, once you have all partitions on the disk backed up, it's possible to only image the C partition (where the Operating System resides), because the others don't change. But, let's not go there right now. We want to image the entire disk - every partition, so that if we need to, we can re-image your disk and it will be exactly like it was, with all settings, applications, etc. intact.
Once an instruction set is made telling Macrium what/when/where to create the backup, it can be modified in the future, should it be required.
The instruction set can be "scheduled" to run automatically, recurring at a certain date/time, or only run once. If you save the instruction set, you can go to it, right-click and select Run Now, to run it at your leisure.
Definition retention rules in the instruction set tell Macrium how many images to save. If you tell it to save 8 images at any given time, it will then remove the oldest backup when it sees 9 images have been completed.
Hope that helps!
