Stop windows 10 hanging on boot up (infinite circle on black screen)

The Problem: Every time I boot up after a normal shut down,  it will sit on a black screen with a spinning windows circle... it will never actually boot.   By holding the power button, it will boot perfectly next time.

This has been driving me mad for a bit... was starting to consider it must have been a dying boot drive or something.  However, the problem is actually a power management issue incompatibility issue.  Basically your computer cannot hibernate properly.  "but I have disabled all hibernation options" I here you say.... yes, so had I, so I thought:

there is a very simple fix:

You need to go to power settings in control panel and switch off "fast start up"... ironically so called.

If you can't find it, here are the steps:

1. Control Panel / Hardware and Sound / Power Options
2. click "Choose What the power buttons do

3. click "change settings that are currently unavailable"

4. Then uncheck "Turn on fast startup"... and I would recommend also unchecking "sleep", as if your system can't fast start, it probably can't sleep properly either.

5. This is what it should look like (Make sure you save changes!)

And enjoy a boot up every time!
