Download Rufus: https://rufus.ie/downloads/
Download windows 10: https://www.microsoft.com/en-us/software-download/windows10 – Create an .ISO to burn with Rufus
When using Rufus to burn the image to the thumbdrive, it is critical that you select MBR partitioning and that BIOS / Legacy mode is selected. WARNING: If this step is not followed and UEFI is used, which is the default for Windows 10 thumb/flash drive deployments, installation and driver support from bootcamp after windows is loaded will fail and you may receive a bluescreen from Intel’s video graphics driver. On top of that the memory allocation will not be in the correct location for DSDT (See links below on how to solve if you cannot reinstall) and your audio will not work out of the box.
Once windows is installed, grab Brigadier.
https://github.com/timsutton/brigadier – Select “Releases” on the right hand side or click here: https://github.com/timsutton/brigadier/releases/
Run Brigadier’s EXE as ADMINISTRATOR and let it run. Ensue the setup located within the BootCamp-041-84821\bootcamp\setup.exe is executed. This process will take about 20-30 minutes to complete as it installs all the stock drivers.
After, run “Apple Software Update”. The first time it may complain about the bootcamp signature not matching but it will still be able to update the “Apple Software Updater” itself. Continue updating and rebooting untill all updates are completed. NOTE: During this process I did receive a hanging white screen once and was required to hold down the power button to hard shutdown upon the boot process and powered it on moments later and the laptop continued to operate as normal.
Exception: During my experience everything installed but the latest “Boot Camp 6 Update for Windows 10”, however, did not impact my deployment at all as my sounds, Wifi and all devices in device driver checked out perfectly fine.
After all updates are completed, move to Windows Update and install all updates and your good to go!
