Windows 10 downloaded, can't start PC

Possom1

Windows has downloaded onto my laptop.

Since then, when I power up my laptop a blue window logo appears on the black screen and there's a little spinning circle as if Windows 10 is starting up.

However the spinning circle soon disappears and nothing happens with the screen remaining black.

What to do...?

I've found this page which refers to the same problem:
http://www.thewindowsclub.com/windows-10-black-screen-problems

The info there states, "You will need Windows 10 Installation Media.". From this link:
http://www.thewindowsclub.com/windows-10-media-creation-tool-create-installation-media-upgrade
"To download the Windows 10 Installation Media Tool, visit Microsoft.com and scroll down till you see two purple Download Tool Now buttons."

Would anyone happen to know where the two purple buttons are which they refer to as I can't seem to locate them.

Not sure about the purple buttons but try this:

Select your language and version of Windows and hit Confirm, then download the ISO. If your machine is from the last few years, you'll want a 64-bit version.
