Disable Secure Boot on Windows 10

Most modern PCs have a feature called Secure Boot. The purpose of this feature is to prevent your computer from booting with unsigned firmware such as drivers and even operating systems. This function protects your computer from malware and other such threats.

However, there are times when you want to disable Secure Boot. It’s easy to do on most computers.

What exactly is Secure Boot on Windows 10?

Secure Boot is a feature on your Windows 10 PC that prevents your computer from booting with untrusted devices. These devices are the ones that Microsoft has not yet approved and digitally signed.

For example, if you create a bootable Linux disk, that disk is not signed by Microsoft. Secure Boot prevents your computer from booting that drive, keeping your PC safe.

Why Disable Secure Boot on Windows 10

You must disable Secure Boot if you want to boot your computer from untrusted devices. For example, if you want to install Linux on your PC and you need to boot from a bootable Linux disk, you must first disable Secure Boot.

Other reasons to disable Secure Boot include the need to install certain graphics cards or other hardware devices.
