The OLED version now uses all different drivers! I didn’t see the drivers page until after the install. I can confirm that Wi-Fi, Bluetooth, and Audio currently do NOT work on Windows, I even tried CCleaner as a last ditch effort and it couldn’t install proper drivers either.
Speaking about dual-boot it looks like valve already add refind script for dualboot support on 3.5.7 https://www.reddit.com/r/WindowsOnDeck/comments/1820sbc/new_os_selector/?sort=new
