Steps to Fix PC Not Compatible with Windows 11

Windows 11 may not be compatible with several systems due to the earlier version of software running on the computer system, but there is nothing to worry about.

Turning on security settings such as TPM 2.0 and Secure Boot will resolve the issue. You will need to make the necessary changes in the BIOS or Basic Input Output System settings.

Click on Recovery from the left panel.

Click on Troubleshoot

Select Advanced Options

Select UEFI Firmware Settings

click on the Restart button

Look for the tab labelled Security

Another way to enable Secure Boot in your PC to make it compatible with Windows 11 is to change the Master Boot Record or MBR partition to the Globally Unique Identifiers Partition Table or GPT.


In the Command Prompt and type in the following commands:

mbr2gpt /validate /disk:0
