Qualcomm Computers Cannot Boot to PXE by Connecting With SCCM Server

Affected Platforms:

• Latitude 7455
• Latitude 5455
• Inspiron 14 Plus 7441
• Inspiron 14 5441
• XPS 13 9345

To reproduce the issue:

1. Set up an SCCM server.
2. Start to deploy the image to the computer by PXE boot.
3. The computer cannot boot to the PXE environment.
   Note: If the computer cannot boot to PXE successfully, the computer moves to the SupportAssist process. Reference the below image.
   
   

The general boot image does not include Qualcomm necessary initial drivers.

Follow the steps below to inject the necessary drivers into boot.wim:

Standard operating procedure of using SCCM server with ARM64 computers

Prerequisites:

• Download Chipset and LAN drivers from Dell.com (https://www.dell.com/support/home/product-support/product/inspiron-14-7441-laptop/drivers)
  Note: This article is using the Inspiron 14 Plus 7441 as our example.
  
  
  

Set up an SCCM server:

1. In SCCM server, Software Library > Overview > Operating Systems > Boot images to find the default boot image for ARM64.
2. To find the location of the boot image .wim file. Right-click Properties > Data Source to find the image path to get the .wim file.
   
3. Start the Command line as Administrator.
4. Copy the .wim file to C:\
5. Create a mount directory to mount winpe.wim file by command, type:

   dism /mount-wim /wimfile:C:\winpe.wim /mountdir:{YourMountFolder} /index:1

   
6. Inject a driver to .wim file, type:

   dism /image: {YourMountFolder} /add-driver /driver:{YourDriversFolder} /recurse /forceunsigned

    
    
   Note: The chipset driver that you downloaded from Dell.com extracts the drivers to the YourDriverFolder.
   
7. Commit the change and save, type:

   dism /unmount-wim /mountdir:{YourMountFolder} /commit

   
8. Copy .wim file to replace in original location. (for example, \\sccm202412\Shared_folder\winpe.wim)
   Note: You can check if the driver is injected using the below method.

   • Check when .wim file is mounted, type:

     dism /image:{YourMountFolder} /Get-Drivers

     
9. Setting the test sequence with the boot image we have injected the driver.
10. Deploy the test sequence with the driver and operating system which you want to deploy.
