A traditional BIOS will boot any software. Typical PCs will normally find and boot the Windows boot loader, which goes on to boot the full Windows operating system. The rootkit could load your normal operating system with no indication anything was wrong, staying completely invisible and undetectable on your system. Secure Boot is designed to stop this.
This prevents malware from hijacking your boot process and concealing itself from your operating system. This feature is, in theory, just designed to protect against malware. So Microsoft offers a way to help Linux distributions boot anyway. Some Linux distributions are philosophically opposed to applying to be signed by Microsoft.
There are two ways to control Secure Boot. The easiest method is to head to the UEFI firmware and disable it entirely. You can can also further customize Secure Boot. You can control which signing certificates Secure Boot offers. Those PCs would then only boot boot loaders approved and signed by that specific organization.
An individual could do this, too—you could sign your own Linux boot loader and ensure your PC could only boot boot loaders you personally compiled and signed. Microsoft requires PC manufacturers implement it in a specific way. For Windows 10 PCs, this is no longer mandatory. PC manufacturers can choose to enable Secure Boot and not give users a way to turn it off. This second key is only recommended. In other words, not all PCs will necessarily boot signed Linux distributions with Secure Boot turned on.
All of the above is true for standard Windows 8 and 10 operating systems on the standard Intel x86 hardware. However, Windows RT is now dead. Code with valid credentials can get through the security gate and execute. Surely, code with bad credentials or no credential will be refused. Seeing the function of Secure Boot, you may want to enable it.
In order to use it, your PC must meet the following requirements. Step 4: Save the changes and exit the menu. Secure Boot works like a security gate. Code with valid credentials gets through the gate and executes. However, Secure Boot blocks at the gate and rejects a code that has bad credentials, or no credential. Contact support.

On some devices, you must first reboot once after enabling UEFI and return to the settings menu in order to enable Secure Boot. It is recommended, but not required, to enable the TPM and virtualization support options as well, in order to enable other security features used by Windows.
You can now boot to media that supports Secure Boot and install an operating system. You can also open msinfo See a problem on this page?
