Secure Boot is only enabled in UEFI mode and when the appropriate keys are loaded. Legacy/CSM, MBR disk, empty Platform Key, or outdated Option ROM devices can prevent the setting from being enabled. The BitLocker recovery key must be checked before making changes.
Secure Boot State: Off
BIOS Mode: UEFI
Confirm-SecureBootUEFI : False
Secure Boot can be enabled when system in User Mode
Secure Boot is only enabled in UEFI mode and when the appropriate keys are loaded. Legacy/CSM, MBR disk, empty Platform Key, or outdated Option ROM devices can prevent the setting from being enabled. The BitLocker recovery key must be checked before making changes.
Do not follow the general internet recipe without recording the brand, exact model, motherboard revision and BIOS version.
Store Boot Mode, disk controller, Secure Boot, TPM, XMP and virtualization status with photos or reports.
Don't do risky firmware without a BitLocker key, Windows recovery USB, stable power and a fallback plan.
Do not change more than one BIOS setting at the same time; Verify Windows and hardware status after each step.
Do not change Secure Boot or CSM settings without obtaining the BitLocker recovery key.
Meaning: Windows firmware support is not visible.
Possible cause: No legacy BIOS/CSM or device support.
Meaning: UEFI is enabled but Secure Boot is not active.
Possible cause: Setting Disabled or keys not loaded.
Meaning: Setting appears to be on but platform is not in user mode.
Possible cause: Platform Key missing or Custom Mode.
Meaning: Boot mode or disk partitioning incompatible.
Possible cause: CSM was disabled in legacy setup.
Meaning: Unsigned bootloader or Option ROM has been disabled.
Possible cause: Old driver, dual boot, or USB media.
Meaning: The hardware/boot device may be legacy-dependent.
Possible cause: Old GPU Option ROM or MBR setup.
Meaning: The command could not access the UEFI Secure Boot API.
Possible cause: Legacy mode or non-administrative PowerShell.
Meaning: Firmware security measurement changed.
Possible cause: Secure Boot key/mod change.

Confirm-SecureBootUEFI
Returns True if Secure Boot is enabled, False otherwise.
Get-Disk | Select-Object Number,FriendlyName,PartitionStyle,OperationalStatus,Size
It indicates that the system disk is GPT or MBR.

Windows Boot Manager and firmware boot interfaces are displayed.
manage-bde -protectors -get C:
Shows recovery protectors before the change.
Get-Tpm | Format-List TpmPresent,TpmReady,TpmEnabled,TpmActivated,ManufacturerIdTxt,ManufacturerVersion

Secure Boot is usually found under Boot or Security; CSM is in a separate menu.
UEFI Boot, Secure Boot, and Legacy Support options are evaluated together.
Unsigned Linux bootloader or old graphics card firmware may be affected.
The Salt BIOS setting usually does not delete files; however, the boot mode, disk controller, TPM Clear or incorrect installation procedures may affect Windows access and encryption keys.
Secure Boot, TPM, BIOS updates, and some firmware changes can change the security measurement and Windows may request a recovery key at startup.
Manufacturers may offer the same feature under different menu names and locations. The exact step must be verified based on the device's full model and BIOS version.
Normal firmware menu usage usually does not void the warranty; opening the case, physical CMOS intervention, or unauthorized firmware operation may affect the manufacturer's conditions.
No. It is more correct to not add unnecessary risk to a working system unless there is a security, hardware compatibility, or manufacturer's stated issue.
Universal password or bypass should not be used. Manufacturer support or the company's IT manager should be used with device ownership proof.
No. Firmware recovery, physical CMOS, disk failure, and data recovery operations require model guide and, if necessary, authorized service.
We safely examine Windows 10/11, Secure Boot, TPM, SSD detection, USB boot and firmware recovery problems according to device model.
