Cheers. I used DDU and it fixed this issue.
There's an options page in DDU - if you're not seeing the safe mode option, check it there (don't do this if you have your login passworded and can only remember the pin). I disconnected my internet connection
I also enabled the stop microsoft from downloading drivers box there - remember to relaunch DDU afterwards and re-enable microsoft automatically installing drivers, or you'll run into trouble down the line, with other hardware.
Don't use the amd cleanup utility - it only works on catalyst - use DDU.
I had no problems using DDU.
Be aware that there is an options page - which is missing from DDU tutorials I've seen online.
You'll want to tick the 'show safe boot ' option at the bottom (as long as you can remember your login password, or like myself, don't have one).
And stop microsoft from automatically installing drivers - but launch DDU again afterwards and undo that (there's a big box for this)
