How to Enable Secure Boot for Windows 11(Complete Guide)

Lucien updated on Jun 21, 2022 to News Blog

For users who want to upgrade from Windows 10 to a newer version, Windows 11 now has some mandatory restrictions on the computer configuration. As part of the system requirements and the Trusted Platform Module (TPM), the device needs to have Secure Boot enabled to install Windows 11.

What is Secure Boot?

Secure Boot is a security feature available on most modern hardware with UEFI firmware that provides a safe environment to boot Windows and prevents malware from hijacking the system during Boot. In other words, Secure Boot allows a computer to start using only trusted software from original equipment manufacturers (OEMs). This is one of the reasons why Microsoft requires Secure Boot to be enabled when installing Windows 11.

If you have a Windows 10 system and want to upgrade to Windows 11, this article will guide you through checking and enabling Secure Boot.

How to Check the Status of Safe Boot Started for Windows 11

1. Open Start, search for System Information, and click the top result to open the app.
2. Click System Summary in the left pane.
3. Check the "Safe Boot Status" information:
On—Indicates that the feature is enabled.
Off — Indicates that the feature is disabled or not supported.

4. Check the "BIOS Mode" information:

UEFI: Indicates that you can enable Secure Boot.
Legacy (BIOS): Indicates that you can enable the feature but requires an extra step.

After completing these steps, if Secure Boot Status is Off and BIOS Mode is UEFI, you can use the steps described below to enable Secure Boot.

If Secure Boot Status is set to Off and BIOS Mode is set to Legacy, you want to create a backup of your computer, use the instructions below to convert the system disk from MBR to GPT, and then proceed with the steps below to enable Secure Boot.

How to Convert MBR to GTP Drive

If you plan to upgrade Windows 10 to Windows 11 on older UEFI-capable hardware, you must first convert the drive from the legacy MBR partition style to GPT to properly switch the system firmware type. On Windows 10, you can use a command-line tool to change the partition type from MBR to GTP without reinstalling Windows.

Check MBR or GPT partition style:

1. Open Start. Search for Disk Management and click the top result to open the experience.
2. Right-click on the drive (the disk location where the Windows 10 system is installed) and select the "Properties" option.

3. Click on the volume tab under the "Partition style" field. If the area is GUID Partition Table (GPT), the drive does not need to be converted, but if you see the Master Boot Record (MBR) label, you can use the conversion tool to switch.

3. Type the following command to verify that the drive meets the requirements and press Enter:

mbr2gpt /validate

Use command to convert MBR and GPT

Tip: mbr2gpt.exe is located in the "System32" folder inside the "Windows" folder. If you want to see all available options, use the mbr2gpt /? command.

4. Type the following command to convert the drive from MBR to GPT and press Enter:

mbr2gpt /convert

Use command to convert MBR and GPT

5. Click the Close button, and click the Shut down your PC option.

After completing these steps, the command line tool will change the partition type to GPT to meet the system requirements for installing Windows 11.

If the conversion is successful, the return code should be "0", but there will be an error code if the process fails.

Special reminder: 
This conversion operation has specific risks, which may cause the system to fail to start. Before doing this operation, you can use a backup tool to back up the system; use tool software to convert to ensure system security.
