Overview

Here's some quick notes on installing Windows 10X on real hardware from cabs using the user-friendly Device Image Generator made by Albacore. For this example, we're assuming a system with no other critical disks installed, and a helpful host system being around to set up the initial image.

This guide has been created for the 20279 version of Windows 10X.

Prerequisites

Host

  • Windows 10 Iron or Cobalt (20279 or 21xxx+) - though 20H2 can also work just fine
  • Utility USB flash drive of ~8GB+

Target

  • Graphics card with DCHU drivers available
  • UEFI system firmware with the ability to disable Secure Boot
  • Boot drive larger than 100 GiB
  • Learn how to disable Secure Boot in your device, and change its boot order to allow booting from the USB Flash Drive

Peripherals

Note: If your device doesn't have a built-in Ethernet adapter, prepare an external Ethernet adapter (USB/USB-C/USB-C Hub with Ethernet). You won't be able to pass through the OOBE without internet connection.

Common: Files & Tools

Workspace

  1. Create a folder called 10X in the root of your drive, e.g, C:\10X
  2. Create a subfolder called Sources
  3. If you are running on a machine that is not the target machine (the one you want to flash Windows 10X onto) create a subfolder called DCHUDrivers
  4. Use v0.3.0.0. release of the Gus's UUPMediaCreator(https://github.com/gus33000/UUPMediaCreator)) to download bits by typing this command in the Command Prompt (where dlfolder is the place to put downloaded bits, e.g., C:\10X\dlfolder, and amd64 specifies the architecture; you can specify arm64 for ARM64 build of Windows 10X):
uupdownload -o dlfolder -s Lite -t amd64 -r External -b Dev -a CB -c fe_release_10x -v 10.0.20279.1002 -z test

Note: you must use -z Test param to download Test build of Windows 10X which includes non-production components.

  1. Put them into Sources folder (e.g., C:\10X\Sources)
  2. Make sure that bits are in Sources folder directly (\10X\Sources\*compdb*.cab should be at this level)
  3. Download overlay.zip from Rafael
  4. Unpack it to your Sources folder (e.g., C:\10X\Sources)
  5. Open command line in the Sources folder and run fixup.cmd in it
  6. Create Tools folder
  7. Create Devices folder
  8. Create FFUs folder
  9. Your resulting folder structure should look like this:
(disk root)
|
-----10X
     |
     ------DCHUDrivers (only if your target machine differs from the one you will build this image)
     ------FM
     ------Sources
           |
           -----appx (includes folders for each AppX)
           -----Retail
                |
                -----%Architecture_Name% (e.g., AMD64)
                     |
                     -----fre (includes the rest of the cabs)
           -----(several top-most cabs with compdb in the name, and .uupmcreplay file)
     ------Tools
     ------Devices
     ------FFUs

Install Tools

Note: Both ADK and WinPE should have the same or higher version as your Windows 10X Image.

  1. [Optional] If you have previous kits (e.g., WP8 Tools), remove them
  2. Download the ADK Insider Preview ISO for your host OS version (only tested with Windows_InsiderPreview_ADK_en-us_20279.iso)
  3. Install Deployment Tools, ICD, Configuration Designer, and uncheck the rest if possible/as needed
  4. Download the Windows Preinstallation Environment ISO for your host OS version (only tested with 20279 version)
  5. Install Windows Preinstallation Environment
  6. Download Windows Image Generator (see tweet)
  7. Unpack it to (disk root)\10X\Tools

Configure Your BSP

Board Support Packages (BSP) is a collection of drivers/settings required to run Windows 10X on a hardware platform. The BSP also includes a set of device drivers that are specific to the components/silicon used in the device, mostly in the form of .inf files and their associated .sys/.dll files.

You will need a BSP for your device if you want it to use all of its devices (WiFi, Cameras, etc.).

To configure your BSP, you need to obtain DCH (Universal) Drivers for your device, and then prepare the OEMDriversFM.xml feature manifest XML file with the links to your drivers.

Prepare DCHU Drivers for Your Hardware

Extracting Drivers From Your Target Machine

This is the case when your target machine is the same you're building this image on.

Example: you have Surface Pro 6 and you want to flash it with Windows 10X. You use Device Image Generator to extract current drivers from your Windows 10 machine.

  1. Go to (disk root)\10X\Tools\ and open DevImgGen.exe
  2. Use the first menu option to extract drivers from the current machine
Using Downloaded Drivers

This is the case when your target machine is different from the one you're building this image on.

Example: you have Surface Pro 6 and Surface Go. You want to flash your Surface Go with Windows 10X. You use Device Image Generator to generate device driver package from the drivers you've downloaded for your Surface Go.

  1. Obtain DCHU Drivers for your hardware (especially GPU)
  2. Go to (disk root)\10X\Tools\ and open DevImgGen.exe
  3. Use the second menu option to generate device drivers package from your DCHU drivers folder, and specify their location at (disk root)\10X\Devices.

[Optional] Edit A BSP for Your Hardware

This is only needed if some of the devices shall not be used.

  1. Use DeviceSpecificDrivers.xml generated by the Device Image Generator, located at (disk root)\10X\Devices and comment out items that shall not be used:
	<?xml version="1.0" encoding="utf-8"?>
	<FeatureManifest Revision="1" SchemaVersion="1.2" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/embedded/2004/10/ImageUpdate">
		<Drivers>
			<BaseDriverPackages>
				<DriverPackageFile Path="C:\10X\DCHUDrivers\Intel\bin\Drivers\iigd_oc" Name="iigd_dc_base.inf"/>
				<!-- <DriverPackageFile Path="C:\10X\DCHUDrivers\SurfaceACPIBattery\bin\Drivers\iigd_oc" Name="SurfaceACPIBattery.inf"/>-->
				<DriverPackageFile Path="C:\10X\DCHUDrivers\SurfacePen\bin\Drivers\SurfacePen" Name="SurfacePen.inf"/>
			</BaseDriverPackages>
		</Drivers>
	</FeatureManifest>

Note: If your target machine is Surface Go, remove reference to SurfaceACPIBattery.inf.

[Optional] Configure Your Image

Note: Not yet supported by the tool (OEMInput.xml is generated on the fly currently).

  1. Edit OEMInput.xml if needed.

Build Your Image

  1. Prepare your environment:

Start > open elevated *Deployment and Imaging Tools Environment

  1. In that window, type this (where C:\ is the drive where your Windows 10 Insider Preview ADK is installed):
C:\> cd c:\Program Files (x86)\Windows Kits\10\Tools\bin\i386
  1. Unless you use a non-prod machine, run this command to unregister the imaging toolchain overrides:
C:\> "%ProgramFiles(x86)%\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\%PROCESSOR_ARCHITECTURE%\DISM\wimmountadksetup%PROCESSOR_ARCHITECTURE%.exe" /q /uninstall
  1. Use third option in the Device Image Generator to begin generation of your Image (ffu). Use (disk root)\10X\FFUs folder for storing your FFU.

Prepare USB Drive for Flashing

Note: You can follow Microsoft docs (Part I: Create Multipartition USB Drive, Part II: Install WinPE), or you can follow these instructions (taken from the docs):

  1. Get an empty Flash drive (with size at least 8GB)
  2. In the same Deployment and Imaging Tools Environment's elevated Command Prompt window open diskpart and press Enter
  3. Follow these instructions to create two disks:
List disk 
select disk X (where X is your USB drive) 
clean 
create partition primary size=2048 
active 
format fs=FAT32 quick label="WinPE" 
assign letter=P 
create partition primary 
format fs=NTFS quick label="Images" 
assign letter=I 
exit
  1. Create Working WinPE files by using this command (where C:\WinPE_amd64 is the location of your choice):
copype amd64 C:\WinPE_amd64
  1. Create bootable media with it (where P: is the letter of the FAT32 partition of your USB Flash drive):
MakeWinPEMedia /UFD C:\WinPE_amd64 P:
  1. Copy your Image (.ffu file) to the I: drive (the second partition of your Flash drive formatted with NTFS)
  2. Download and add gdisk64.exe file to the root of your WinPE partition (P: in this example)

Apply Your Image

Apply Your Image on Machine Without Windows 10X Installed On It

  1. Boot from WinPE drive
  2. Open diskpart
  3. Type this:
list disk

Take a note of the name of your device's main disk drive, e.g., disk 0 4. Type exit to leave diskpart 5. Use this command (and specify the correct path to the ffu that you created above, as well the id of your physical drive):

dism /apply-ffu /imagefile:C:\\YourDevice.ffu /applydrive:\\.\physicaldrive0
  1. Once complete, remove your USB flash drive
  2. Type exit in the Command Prompt window

Apply Your Image on Machine With Windows 10X Installed On It

  1. Boot from WinPE drive
  2. Type notepad to open notepad
  3. Use File-->Open to find the name of your WinPE disk
  4. Type this to identify the id of your physical drive:
spaceutil get-drive -poolname ospool
  1. Type this (where D:\ is the name of your WinPE disk and 0 in the end of physicaldrive0 is the id of your physical drive):
cd D:\
gdisk64 -l \\.\physicaldrive0
  1. Make sure that it contains OSPool and other partitions of Windows 10X
  2. Type this to clean up the drive (where 0 in the end of physicaldrive0 is the id of your physical drive):
gdisk64 \\.\physicaldrive0
o
w

and press Enter

  1. Use this command (and specify the correct path to the ffu that you created above, as well the id of your physical drive):
dism /apply-ffu /imagefile:C:\YourDevice.ffu /applydrive:\\.\physicaldrive0
  1. Once complete, remove your USB flash drive
  2. Type exit in the Command Prompt window

Load Windows 10X

At this time, your Windows 10X will boot. If everything is correct you should see the OOBE.
