‘The PC Must Support Secure Boot’ Error: How to Fix

If you’ve been following the Windows 10 trend for the past few days, we’re sure you must’ve come across terms like TPM and Secure Boot. If you have and are curious to know why Microsoft has mentioned them under mandatory requirements for their latest version of Windows 11, you’ve come to the right place.

In this post, we’ll be taking a look into what Secure Boot is and why Microsoft has made it a requirement for their upcoming release.

If want to read about TPM and how it affects your Windows 11 experience, we recommend reading this piece from another one of our amazing writers.

What is Secure Boot?

Secure Boot is a crucial part of UEFI (Unified Extensible Firmware Interface), something that has now replaced the old text-based BIOS that we used to have in pre-Windows 8 era PCs. Just by looking at it in your PC’s firmware settings, it may seem like a simple toggle but in reality, it is much more than that.

Secure Boot, as the name suggests, plays a vital role in your PC’s boot process. It comes into play as soon as you press your PC’s power button and remains in play during the booting process.

Its role is to check every driver, application, and even your bootloader that is queued up in the boot queue and ensure that no harmful application manages to get through the security checks without proper validation. If Secure Boot is unable to verify the signature/key of the application, it’s simply denied execution on boot.

Think of it as a security guard posted outside a military-controlled area, looking for potential threats. Once the guard has verified your identity via a government-issued ID card (signature/keys in our case), only then you’re allowed to enter the premises.

To be honest, the app does a wonderful job of checking your hardware and reporting if something fails to fulfill many of Windows 11’s systems requirements.

Why does Windows 11 need Secure Boot?

The Covid-19 pandemic has forced the world to work from home. Looking at the always-online nature of our PCs today, security has become the number one area of concern.
