I have a Probook 450 G3 notebook. After running PC health check, I realized that my laptop is not compatible with Windows 11 because the message reads that secure boot is not supported. The BIOS on my laptop allows me to enable or disable secure boot, but why is it marked as unsupported in both system information and PC health check?

Hi:
You can't enable secure boot if W10 is installed in Legacy mode.
You can only enable secure boot if W10 is installed in EFI mode.
To install W10 in EFI mode, you have to boot your W10 installation media from one of the EFI boot sources found in the F9 boot options menu.
You can confirm that W10 is installed in Legacy mode by going to the W10 programs list>Administrative tools>System information.
Here is a screen shot of mine. I have highlighted the line (BIOS Mode) that will show how Windows is installed...yours will show Legacy, where mine shows UEFI.
