Oh, I am SO glad, mate 
It was a concern of mine that you might be disconsolate, and I could not blame you.
That memtest can be a PITA for the time it takes, and some have reported for just having to break out of it. But if it gives the all clear on the RAM sticks, then the msdos over gpt option seems to my mind to be the next logical step.
Manufacturers can have a mindset focused on orienting their product to a certain OS, and so there can be impediments in our way to installing our beloved Linux that can be difficult to overcome. I have a lot of empathy for persons employed as Help Desk Support, and wish I could be sitting at your shoulder and perhaps cry out "I know what it is. Do this." Lol.
Keep the faith, and one way or another you/we will crack this bugger.
Cheers
