Disabling USB Boot

Rationale

Disabling USB boot prevents the device from booting another operating system, which could otherwise be used to manipulate or overwrite IGEL OS on the internal storage, whether intentionally or accidentally.

Instructions for IGEL Devices

USB boot is disabled by default in factory settings on IGEL UD LX devices.

If it has been enabled and you want to disable it again, follow these steps:

1. Hold down the [Del] key ([F2] for UD2 devices) while the system is booting.
   The UEFI menu opens.

2. Use the arrow and return keys to navigate to SCU.

3. If prompted, enter the UEFI password (if one is set).
   The Setup Utility opens.

4. Go to the Boot section.

5. Set USB Boot to Disabled.

6. Press [F10] to save and exit.

7. Confirm Exit Saving Changes? when prompted.
   The device will reboot.

Set a UEFI Password to prevent unauthorized users from re-enabling USB boot or altering boot settings.
