Upgrading to Windows 11 requires your PC to meet certain system requirements. Among these, Secure Boot—a security standard developed by members of the PC industry—plays a critical role. Secure Boot helps to protect your system against security threats before they can infect your system, but it must be enabled before you can install Windows 11. If Secure Boot is not enabled or supported, users may encounter errors during the upgrade process from earlier versions of Windows.
To ensure a successful upgrade to Windows 11, your system’s firmware needs to support UEFI (Unified Extensible Firmware Interface). UEFI is a modern firmware type that offers several advantages over the older BIOS firmware, including faster startup times and support for larger hard drives. With UEFI, Secure Boot can be enabled, which is a mandatory step for installing Windows 11. If you’re experiencing issues with Secure Boot while trying to upgrade, verifying your UEFI settings and making sure your hardware meets the requirements is our first course of action.
We’ve seen several cases where users think they have enabled Secure Boot, yet they still run into errors. It’s not unusual for there to be a discrepancy between the firmware settings and what the installation media requires. Therefore, checking if Secure Boot is properly configured is essential. If Secure Boot is off or unsupported, certain changes in your PC’s firmware settings may be necessary before moving forward with the Windows 11 installation.

Understanding Secure Boot and UEFI
To effectively troubleshoot Secure Boot errors during the Windows 11 upgrade, it’s essential to grasp the roles of Secure Boot and UEFI.
What Is Secure Boot?
Secure Boot is a security standard designed to ensure that a device boots using only software that is trusted by the Original Equipment Manufacturer (OEM). When enabled, it prevents malware from hijacking the boot process, which can compromise your system before the operating system loads. It’s a critical component in the chain of trust for system integrity.
Key Aspects of Secure Boot:
- Part of the UEFI firmware specification.
- Protects the boot process from malicious attacks.
- Mandatory for the optimal operation of Windows 11.
What Is UEFI?
UEFI, which stands for Unified Extensible Firmware Interface, is a modern firmware interface for computers that serves as a replacement for the older Basic Input/Output System (BIOS). UEFI offers a more robust solution with a more user-friendly interface and additional capabilities like graphical menus and remote diagnostics.
Key Features of UEFI:
- Succeeds the legacy BIOS firmware interface.
- Supports large hard drives (over 2TB) and quicker boot times.
- Provides a foundation for Secure Boot.
How Secure Boot and UEFI Relate
Secure Boot is a feature of the UEFI firmware. The two collaborate to enhance the security of the system during the boot process. While UEFI defines the platform, Secure Boot uses policies dictated by the UEFI specification to verify the integrity of the bootloader and other startup software. One cannot function without the other, making the partnership essential for a secure and reliable startup process.
| UEFI | Secure Boot | Function |
| Firmware Interface | Security Standard | Verifies boot software integrity |
| Replaces BIOS | Part of UEFI Specification | Blocks unauthorized software |
| Supports Modern Features | Requires TPM 2.0 | Ensures Device Security |
Preparing Your PC for Windows 11 Update
To upgrade to Windows 11, we’ll ensure our PC meets the system requirements and that the firmware settings are correctly configured. Our focus will be on checking if our hardware is compatible, enabling necessary features in BIOS, and preparing our drive for the upgrade.
Checking System Requirements
Enabling TPM 2.0 and Secure Boot
Our PC needs TPM 2.0 and Secure Boot enabled for Windows 11. These features provide enhanced security and are mandatory for the update. We’ll restart our PC and enter the BIOS Settings to enable TPM (Trusted Platform Module) 2.0 and Secure Boot. It’s crucial to save changes before exiting the BIOS.

Troubleshooting Common Secure Boot Errors
When upgrading to Windows 11, Secure Boot errors can be a roadblock. We’ll address the most frequent issues and provide concise steps to resolve them, ensuring a smoother upgrade process.
Invalid Signature Detected
If your system highlights an “Invalid Signature Detected” message during boot, it’s an indication that you’re dealing with authentication problems. This often occurs when you have unsigned or improperly signed drivers.
- Restart the computer and enter the UEFI Firmware Settings.
- Locate the “Secure Boot” section and ensure it’s set to “Standard” or “Custom” mode.
- Check for any unauthorized changes in the boot software that might have resulted from malicious software.
Secure Boot Not Enabled
When Windows 11 refuses to install due to a “Secure Boot Not Enabled” error, it’s clear we need to toggle this vital security feature on in our system’s BIOS.
| Fixing “Secure Boot Not Enabled” Error |
| Restart the PC, and access the BIOS menu. Search for “Boot” options, and ensure Secure Boot is enabled. If problems persist, consult the manufacturer support website or visit a PC repair shop for professional assistance. |
Secure Boot Configuration Issue
A “Secure Boot Configuration Issue” typically pops up when settings are misconfigured in the BIOS or the system is in Legacy BIOS mode instead of UEFI.
- Enter the UEFI firmware settings through the BIOS menu.
- Verify that UEFI is enabled and that Compatibility Support Module (CSM) is disabled.
- If the fix isn’t clear, seeking guidance from your PC’s manufacturer support can provide model-specific instructions.
In cases where the TPM chip isn’t recognized, confirm in the UEFI firmware settings that TPM is present and enabled to support Secure Boot. Disabling any legacy options typically solves Secure Boot misconfiguration issues, aligning your system’s core security with Windows 11 requirements.
Advanced Steps for IT Professionals
When updating to Windows 11, encountering a Secure Boot error requires precise advanced troubleshooting. It’s essential to ensure Secure Boot is enabled and properly configured in the BIOS/UEFI settings, which can differ across manufacturers such as Lenovo, HP, and Dell. Let’s tackle some sophisticated methods to resolve the Secure Boot hurdle for a seamless upgrade.
Using Command Prompt for Repair
In instances where Windows does not boot, using the Command Prompt from the Advanced Options menu offers a powerful way to repair startup issues. Start by accessing the Advanced Options:
- Restart the system while holding down the Shift key to enter the boot options menu.
- Navigate to Troubleshoot -> Advanced options -> Command Prompt.
Once in the Command Prompt, you can use commands like bootrec /fixboot and bootrec /rebuildbcd to repair boot issues. Additionally, for systems equipped with both Windows and Linux, ensure that the boot configurations are not conflicting.
Accessing BIOS for Manual Configuration
Correct BIOS/UEFI configuration is critical. Upon startup, repeatedly press the specific keyboard key (often F2, F10, F12, or Del) to enter the BIOS/UEFI setup. Manufacturers may have different interfaces, but the goal is the same:
- Enable UEFI/BIOS mode—switch away from ‘Legacy’ or ‘CSM’ modes.
- Ensure the Trusted Platform Module (TPM) is enabled. Look for TPM settings, which might be referred to as AMD fTPM switch or a similar term on AMD motherboards.
- Enable Secure Boot and select the correct key management option. Set up Secure Boot to work with Windows 11.
Check the manufacturer’s documentation or support to find specifics for BIOS keys and settings needed for models from Lenovo, HP, Dell, etc.
Legacy to UEFI Without Data Loss
Converting a system’s boot mode from Legacy to UEFI without data loss is achievable:
- Confirm the current BIOS mode via System Information (msinfo32).
- If the BIOS mode is set to Legacy, create a backup to avoid any data loss during the conversion process.
- Use tools like MBR2GPT.EXE, which can convert the disk without data loss. Run this tool from the Command Prompt in Windows Preinstallation Environment (Windows PE) or from the live Windows 10 system.
| Step | Action | Tools/Commands |
| 1 | Boot into Windows PE or live system | Command Prompt |
| 2 | Verify disk’s partition style | msinfo32 |
| 3 | Convert the system drive | MBR2GPT.EXE |
After these steps, reboot to the BIOS/UEFI and switch to UEFI mode. This will maintain the integrity of your system and allow a seamless upgrade to Windows 11 while adhering to the new security standards. Remember, encryption and secure data handling should always be prioritized during this process.
