Yes, if your system information shows that Secure Boot is unsupported, it could definitely be the reason you're encountering the VAN 9003 error. VAN 9003 is related to configuration issues with Secure Boot or TPM on your system. To resolve this issue, you need to enable Secure Boot in your BIOS/UEFI settings. Note that your system should be set to UEFI mode rather than Legacy BIOS. Enabling Secure Boot on a system configured with Legacy BIOS can render your Windows installation unbootable.
Follow these support articles for detailed instructions on how to proceed:
1. Addressing Virtualization-based security (VBS) settings on Windows 10 (VAN9005, VAN9002)
2. Troubleshooting the VAN9001 or VAN 9003 Error on Windows 11
3. Vanguard Restrictions
If needed, consult your computer's manual or manufacturer support for specific steps to change BIOS/UEFI settings.
