EX 3 Redisguise

Redisguise is the process of updating and restoring on the system using a bootable USB drive.

This process can be used to update to a newer OS image, or revert to a previous OS image.

To identify which OS image your system currently runs, please go to Disguise Manager > Help and select About Manager.

You will need

  • A 16GB USB memory stick
  • A version of Rufus to turn it into a bootable disk. Ensure the volume name of the usb is: REDISGUISE
  • An internet connection to the machine you are re-imaging
  • An OS image from the Download Centre.
  • 7-Zip archive tool/file manager.

Create a Bootable USB

  1. Download the ISO from the Download Centre.
  2. To create a Bootable USB stick open Rufus, click Select and browse to the downloaded ISO. Then click Start.

The Partition scheme, Target system, and File System fields should appear automatically.

Rufus settings

    The settings should be:
    - Partition scheme - GPT
    - Target system - UEFI - non CSM
    - Volume label - Automatically pulled from ISO file
    - File system - NTFS

Booting into the USB

An internet connection is required for Windows licensing, but reimaging can still be completed offline. However, without a connection, you may encounter an “Activate Windows” overlay.

If Windows is not activated, a watermark will appear in the bottom-right corner of your screen. The message, “Activate Windows. Go to Settings to activate Windows,” will overlay all active windows and applications.

  1. Plug the USB Drive into your Disguise server and switch it on.
  2. To enter the BIOS, wait for the Disguise logo to appear and then continue pressing the Delete key until the BIOS screen appears. You can navigate the BIOS using the left and right arrow keys.
  3. Change the Boot option #1 to the USB stick.
  4. Navigate to the Advanced tab and press Enter to view the CSM Configuration and ensure that Boot option filter is set to [UEFI and Legacy]. If not, then press F4 and change it. Confirm and re-enter BIOS.
  5. Once this setting is confirmed, navigate to the Save & Exit tab to the right of your current tab.

  1. In the Boot Override section, select the following option:

    UEFI: [diskname], Partition 2

    The diskname may vary depending on the manufacturer of the USB stick in use.

    The Redisguise process will run automatically until the reimaging has completed.

If the re-image is unsuccessful, a log file will be automatically generated and stored on the USB memory stick. Please send this log file if you need to contact Disguise support.

If you experience any problems during updating or restoring the system, or any of these instructions are unclear, please contact the Disguise support team.
