GX 3 Redisguise

Redisguise is the process of updating and restoring 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.

Warning

Performing a system restore from the new disk image will erase any valuable data on your system drive. Please ensure you make a back-up of any essential files from your system (C:) drive before initialising this process. The process does NOT destroy any media or projects on your media drive.

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.

Note

Prior to 2024, the OS versions consisted of 3 parts due to the way the data was compressed. Where this is the case, using 7-Zip, place all 3 parts in the same directory and extract any one part. Z-Zip will automatically continue to extract the other 2 parts to create the full ISO image.

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.

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

Warning

These settings are critically important. The re-image process will fail if they are not set correctly.

Note

On the latest versions of Rufus you may see this warning. This is expected and does not apply to current Disguise hardware. Please click OK to continue as normal.

Booting into the USB

---

Warning

When updating from an OS up-to and include 24Q1 to 24Q2 or above, you must ensure internet is disconnected from the server. If you do not Windows will fail to activate and you will need to repeat the reimage process.

1. Plug the USB Drive into your Disguise server and switch it on.
2. Depending on the OS you are reimaging to, you may or may not need to be connected to the internet.
   • If upgrading from OS 24Q1 or below to OS 24Q2 or above, ensure the internet is disconnected from the server.
   • If upgrading to a version older than 24Q2 make sure the machine is connected to the internet for Windows activation.
3. To enter the BIOS, wait for the Disguise logo to appear and then continue pressing the Delete key until the BIOS screen appears.
4. Navigate the BIOS screen using the left and right arrow keys until you reach the Save and Exit tab.

Please do not select Save Changes. You only need to access the BootOverride.

5. 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 reimage 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.

Additional Information

If Windows has not been activated correctly it might be that your PC was connected to the internet. Please see TA-60.
