Answer 1

Download the latest Raspbian Stretch with Desktop (currently 2017-09-07) :

https://www.raspberrypi.org/downloads/raspbian/

Flash to sd card using Etcher (on Mac,PC,Linux) :

https://etcher.io

Note : sd card does not need formatting, nor the image file unzipping with this process

Place sd card into Pi and boot

Answer 2

I've found this, although it's for ubuntu, debian and derivates... but might work. Try configure X for every one:

sudo dpkg-reconfigure x11-common

and then choose "anyone".

Answer 3

You need to run it using root.

   sudo startx

Answer 4

Sudo startx takes me to the default desktop with root powers. This is not the right way to start the GUI!

For a while startx was not working on mi pi3. I had to change raspi-config to boot to desktop with password prompt. It was the only way to access the GUI. For whatever reason, startx now works. I made no changes other than configuring to boot to console (startx still wasn't working) and back to GUI and back to console (and now it works). I pulled my hair out for nothing.
