advice on how to

I'm new to true image 2015 and have already run into some problems. I watched "how to videos" and read through the user manual that comes with product.
I should mention I'm using Windows 10 now. I was fine with windows 8.1 and True Image 2014. Thought this would be more user friendly- but.....
Still am stuck.
This is what I'd like to accomplish, can someone verify the steps are correct?

I want to back up my entire PC (first time). I want to do a "full version" and I want to be able to validate it after the back up is made.
I plan on using a brand new WD my passport with only wd drive utilities installed in that.

So, I go to "backups" and choose "entire pc"-
I assume it automatically knows I want everything but first time a config menu came up and wouldn't let me leave the page? Ended with major error codes....all repaired and ready to try again. That's why I'm asking for help first!

Does the program by "default" then name the back up for me? I'm confused on that one.
Please explain.

I assume after that I go to "options" and choose "full " under type of back up. Do I have to choose "custom" first to get to "full "? That is not clear to me (sorry I know this is all basic for all of you).

After that step, I go to "advanced" to choose "validate when finished options" and make sure for my needs I mark "no schedule" as I want this to be a system back up. I will do another in a month or so and then only when I have new things I want saved. I use other external hard drives already to back up all the important things (photos, documents to keep...). So I don't need incremental settings.

And then I should be able to choose "external hard drive " to back up to (that may have already come up...)
and click "back up now".

is it that easy or am I missing some key things I need to do? Please confirm and correct as needed.
I am hoping to attempt to make my first back up this weekend.
