UEFI Settings Missing in BIOS? How to Check if Your PC Supports UEFI
Before attempting any potential fix, you need to verify that your #PC’s motherboard is equipped to support UEFI. If your PC is an older model, the chances are that the #uefi #firmware #settings are unavailable.
Press Win + R to open the Run command dialog box.
Type msinfo32 and press Enter to open the System Information screen.
Select System Summary on the left-hand side pane.
Scroll down on the right-hand side pane and locate the BIOS Mode option. The BIOS Mode value should either be "UEFI" or "Legacy." If it's "Legacy," then you don't have UEFI Firmware Settings on your PC.
