Since you've already configured your BIOS and Windows to UEFI mode but are still encountering the VAN 9003 error, ensure that Secure Boot is enabled in your BIOS settings. Follow these steps:
1. Access BIOS/UEFI Settings: Restart your computer and press the designated key (usually F2, F10, DEL) to enter BIOS/UEFI settings.
2. Enable Secure Boot: Locate the Secure Boot option (commonly found under the "Security" or "Boot" tab) and enable it.
3. Save and Exit: Save your changes and exit the BIOS setup.
If Secure Boot was already enabled or you continue facing issues:
- Update Windows: Ensure your Windows is fully updated.
- Check TPM Settings: Verify that TPM (Trusted Platform Module) is enabled in your BIOS settings.
For detailed steps, refer to the relevant support articles:
