FOG Imaging Walkthrough



This article provides the information on "FOG system Imaging process Walkthrough".


NOTE: This imaging process may not work with all Dell system configurations.
NOTE: This requires good working knowledge of the FOG imaging application and Linux operating system commands. For more information on FOG imaging see the Fog User Guide.




Prepare your FOG server for modern Dell systems with the latest boot Kernel:

  1. Go to Fog Configuration

  2. Go to Kernel Update (Make sure the FOG server can reach the Internet)

  3. Download Kernel 4.1.2 on the Kernel Update page

  4. Save Kernel 4.1.2 as bzImage412
  5. Go to FOG Settings

  6. Go to TFTP Server

  7. Change FOG_TFTP_PXE_KERNEL to bzimage412

  8. Click Save Changes

Host Registration

  1. PXE Boot the Target System
  2. Choose Perform Full Host Registration and Inventory

  3. Go to Hosts in the FOG interface:

  4. Select the Target Host:
  5. Go to Basic Tasks
  6. Select Upload

Prepare the OS Upload for FOG

On the target machine:

  1. Install the Windows OS and all updates and drivers
  2. Install the FOG Client and FOG prep tools from the Fog Client page (Link at the bottom of all FOG pages):


  3. Shrink the partition of the Windows drive but leave 2048MB for the sysprep OOBE process when you restore the image:

    • Right click on the C: partition
    • Choose Shrink Volume

      • Subtract 2048 from the amount of space to shrink:

  4. Run Sysprep with Generalize, OOBE, and Quit.

  5. Run FOG Prep
    NOTE: Some drivers may not sysprep properly and should be uninstalled prior to sysprepping. If you receive errors in the sysprep process, a setuperr.log will be in Windows\System32\Sysprep\Panther
  6. Restart the system and start the PXE process.

If FOG fails when attempting to start the partclone process with either a hang or an invalid partition table message, you will have to make sure any GPT data is wiped from the disk by running sgdisk.

  • Boot from a Linux key and issue the following command to clear GPT data from the disk:
    • sgdisk -z /dev/sda
  • Restart the system and start the PXE process.

FOG should capture the image successfully.
