WN25-00-000460 - Windows Server 2025 systems must have Unified Extensible Firmware Interface (UEFI) firmware and be configured to run in UEFI mode, not Legacy BIOS.

Information

UEFI provides additional security features in comparison to legacy BIOS firmware, including Secure Boot. UEFI is required to support additional security features in Windows, including Virtualization Based Security and Credential Guard. Systems with UEFI that are operating in 'Legacy BIOS' mode will not support these security features.

Solution

Configure UEFI firmware to run in UEFI mode, not Legacy BIOS mode.
