Windows 11 is strict on the system requirements needed to upgrade your computer to this latest operating system by Microsoft. Requirements like TPM 2.0 and Secure Boot are becoming one of the major reasons for not receiving Window 11 updates. This is why even 3-4 years old computers are standing incompatible with Windows 11. Fortunately, there are various ways to bypass these requirements. In this article, we are going to explore how to install Windows 11 on Legacy BIOS without Secure Boot or TPM 2.0.
How to Install Windows 11 on Legacy BIOS without Secure Boot or TPM 2.0
What is Secure Boot?
Secure Boot is a feature in start-up software in your computer that ensures your computer begins safely and securely by preventing unauthorized software, such as malware, from taking control of your computer at boot-up. If you have Windows 10 modern PC with UEFI (Unified Extensible Firmware Interface), you are being protected from malicious software trying to take control of your computer when it starts up.
What is TPM 2.0?
TPM stands for Trusted Platform Module. When you turn on a newer PC with full-disk encryption and a TPM, the little chip will generate a cryptographic key, which is a one-of-a-kind code. The drive encryption is unlocked and your computer will start up if everything is normal. Your PC would not boot up if there is a problem with the key, for example, if a hacker tried to tamper with the encrypted drive.
Both these features boost Windows 11 security making you the only person to log in to your computer.
