Build and Prepare the Reference Machine

  • Install your operating system (such as Windows 10 or 11) on a reference computer or virtual machine.
  • Install all required updates, drivers, and software applications. [1]
  • Enter Audit Mode (press Ctrl + Shift + F3 at the initial out-of-box experience screen) if you need to add final customizations.
  • Run Sysprep to generalize the operating system so it can deploy to different hardware:
    • Open Command Prompt as an administrator.
    • Navigate to C:\Windows\System32\Sysprep\.
    • Type sysprep.exe /oobe /generalize /shutdown and press Enter. The PC will turn off once generalized.

Register the Reference Host in FOG

  • Turn on the reference computer and immediately set it to PXE boot (network boot) via your BIOS/UEFI boot menu.
  • From the FOG boot screen, choose Perform Full Host Registration and Inventory or Quick Registration.
  • Allow the registration to finish and let the machine reboot, then shut it down again.

Create the Image Definition in FOG Web UI

  • Log in to your FOG Server Web UI using your browser.
  • Click the Image Management icon (looks like a picture) on the top menu.
  • Select Create New Image on the left menu.
  • Fill out the image parameters:
    • Image Name: Type a clean name with no spaces or special characters (e.g., Win10_Golden).
    • Storage Group: Choose default.
    • Operating System: Select the correct OS type (e.g., Windows 10/11).
    • Image Type: Choose Multiple Partition Image – All Disks for modern Windows installations, or Single Partition if applicable.
  • Click Add to save the image profile.

Associate Image and Run Capture Task

  • Go to Host Management -> List All Hosts and find your reference computer.
  • Click Edit on that host.
  • Locate the Host Image drop-down menu, select the new image you just created, and click Update at the bottom.
  • Go back to the host details or active tasks, and select Basic Tasks -> Capture (Upload).
  • Power on the reference computer and let it boot via network (PXE). The FOG server will automatically pull the disk image and store it.
