How to Enable Secure Boot on Your Dell Device

What is Secure Boot?

Secure Boot protects the boot process against security attacks from malicious code like malware and ransomware. Secure Boot is firmware-dependent and requires that the computer BIOS is set to UEFI mode.

How to Verify that Secure Boot is Enabled.

1. Click the Windows Button to the bottom left of the screen or press the Windows Key.
    
2. In the Search Bar, type: msinfo32
    
3. Press Enter.
    
4. System Information opens, and System Summary should be selected by default.
    
5. On the right side of this screen, look for BIOS Mode and Secure Boot State.
    
6. If Secure Boot is enabled, the BIOS Mode shows "UEFI," and Secure Boot state shows "On" (Figure 1).

If the BIOS Mode shows "Legacy" in the Boot setting in the computer BIOS, it must be switched from Legacy to UEFI mode.

Verify that your computer was tested for the upgrade to Windows 11 before you continue as older computers may not meet the Windows 11 system requirements.
