Introduction:

UEFI is the abbreviated form of the Unified Extensible Firmware Interface. This is an interface that will replace the BIOS to configure the hardware and load and start an operating system. It was first introduced by Intel as the Intel Boot Initiative, which was then changed to EFI. Then EFI was taken over by the unified EFI forum and was therefore named UEFI. UEFI comes with a boot manager.
In addition, it offers faster start-up and better network support.
Windows PCs are increasingly equipped with UEFI support.

Steps to follow:

To check if your PC supports and uses UEFI / EFI or BIOS, follow the steps below.

1. Open File Explorer and navigate to the following folder: C: >> Windows >> Panther.

2. In the folder named Panther, open the text file called setupact.log. The file opens automatically in Notepad.

3. After you open setupact.log, click Ctrl + F to display the search box then search for an entry labelled Detected BootEnvironment, and then click Next.

4. Once you have detected the detected boot environment, you will notice the BIOS or UEFI words listed as follows:
Callback_BootEnvironmentDetect: Detected Boot Environment: BIOS

OR

Callback_BootEnvironmentDetect: Detected Boot Environment: UEFI

If you use UEFI, it will display UEFI! If your PC supports UEFI, then, if you go through the settings of your BIOS, you will see the Secure Boot option.
In general, UEFI-enabled machines have faster start-up and shutdown times than BIOS-based machines.
