Just wanted to say thanks, this worked perfectly! And it's even better than the default Windows installation that came with my Yoga Book - for example, the Halo Keyboard app has more options. :laugh:
I used the 'English (International)' iso as I'm in the UK, and this worked fine. I noticed OP asserted a few times in this thread that Win 10 Pro is only for the 128GB model - actually, my 64GB device came with Win 10 Pro (you can tell by checking if there's a 'Pro' hologram sticker on the back of the device.)
The first time I tried my USB stick, I told it to overwrite the existing Windows installation, and process failed after a few minutes (and corrupted the existing installation). The second time, I formatted the main partition first, then installed it on there, and everything went without a hitch. :victory:
My Yoga Book now feels more responsive than ever, and seems to be fully functional. Thanks very much for putting the effort into making this guide.
