Enable secure boot status in lenovo | Not secure boot | Simple Bios setting
Firstly, you need to try enabling the OS-optimized default option in the Exit tab of the BIOS. The BIOS interface may change depending on your PC’s model and brand. If the first method does not work, then try the second method, which involves restoring your factory keys in the Security tab. I hope either of these methods will work for you. You can check the Secure Boot status by typing 'System Information' in Windows search and selecting the corresponding option. This will display the details of your PC, where you can find the Secure Boot status condition. Have a nice day.
