secure boot state unsupported

The "Secure Boot State Unsupported" message typically means that the Secure Boot feature is either not enabled, not supported by the hardware, or the system is not configured correctly to use it. Secure Boot is a security feature in UEFI firmware designed to ensure that only trusted software runs during the startup process. Common causes for Secure Boot State Unsupported include:

• Secure Boot is disabled in the BIOS/UEFI settings.
• The BIOS mode is set to Legacy instead of UEFI.
• The boot disk uses the MBR partitioning scheme instead of GPT.
• TPM (Trusted Platform Module) is disabled.
• The hardware or motherboard does not support Secure Boot.
• Outdated BIOS/UEFI firmware.

To fix this:

1. Enter BIOS/UEFI settings and enable Secure Boot.
2. Enable TPM in the BIOS if available.
3. Switch the BIOS mode to UEFI if it is set to Legacy.
4. Ensure the boot disk uses GPT partitioning.
5. Update the motherboard BIOS/UEFI firmware if needed.
6. Check motherboard documentation for Secure Boot support.

If the hardware fundamentally lacks support for Secure Boot, it may be impossible to enable the feature. These steps address the Unsupported Secure Boot state seen on Windows 10/11 systems and other UEFI-based setups, helping to meet security requirements and enabling OS upgrades like Windows 11.
