  2. In the Search Bar, type: msinfo32

  4. System Information will open, and System Summary should be selected by default.
     
  5. On the right side of this screen, look for BIOS Mode and Secure Boot State.

If the BIOS Mode shows “Legacy” in the Boot setting in the computer BIOS, it must be switched from Legacy to UEFI mode.

Verify that your computer was tested for the upgrade to Windows 11 before you continue as older computers may not meet the Windows 11 system requirements.
