All I can offer is what I found when installing on a Dell XPS 15

GPT is some type of partition format, I think. I had to use gparted 
while booted from the USB in order to reformat with gpt.

I was told several times (and I had concluded anyway) that I should 
*not* use UEFI.

I set the BOOS to secure boot disabled, and legacy boot enabled (ie no 
UEFI). That worked.

My assumption would be that the 4th partition is the one that needs 
establishing as GPT before formatting. But I may have misunderstood 
this, as I was using the whole disk.

I don't know the answer to this as it's a dual boot. I assume that Linux 
installers will see that Windows is installed, and put a working Grub on 
the boot area of the primary partition. Apparently in a single-install 
(Linux-only), the installers no longer create a boot partition but 
install Grub on the main partition.

But again, this is largely guesswork on my part — as you say, the web 
pages disagree wildly.
