Who are you referring to when you say "your tutorial"? Because what goes on on the editorial side of things, where you see reviews and articles, is strictly "other side of the fence" from what goes on in the forums. And in the forums, there are literally hundreds, or more, of members who've posted various "tutorials" through the years. So, what tutorial are you referring to?
As to posting images here, my guide explains how to do that.
Personally, I much prefer using a desktop partition manager application when it comes to managing partitions and formatting drives (Except when it must be done outside of the Windows environment), and the free version of Paragon partition manager is what I primarily use. It does practically anything you could want to do when it comes to managing partitions and formatting on any flavor of drive.
Quickly organize and optimize partitions on your internal and external disks and media for free.
