If you have ever installed or reinstalled Windows operating system on any computer or laptop, you are probably aware of BIOS (Basic Input/Output System). Most of the time, we need to change the BIOS settings to enable boot from CD/DVD or USB. BIOS (Basic Input/Output System) is now outdated, and PC manufacturers are replacing the outdated BIOS (Basic Input/Output System) with the new UEFI (Unified Extensible Firmware Interface).
If you recently purchased a computer or laptop, most probably it will ship with UEFI/EFI.
UEFI comes with more features when compared to the outdated BIOS and solves many BIOS limitations. For example, unlike BIOS, UEFI systems boot faster and support over 2 TB hard disks with a GUID Partition Table (GPT). Almost all PCs ship with Windows 10/8 support UEFI firmware.
Further, I want to let you know, there’s no way to switch from BIOS to UEFI on an existing PC. You have to buy new hardware that supports UEFI. Most UEFI implementations provide BIOS emulation, so you can choose to install and boot old operating systems that expect a BIOS instead of UEFI, so they’re backward compatible.
If you aren’t aware of whether your PC is booted into UEFI or legacy BIOS mode, you can check PC’s user manual or even find the details on the manufacturer’s website. Still, there is an easier way to find out the current boot environment without using third-party tools in Windows 10/8.
How to check if your PC supports UEFI/EFI on Windows 10/8?
To check if your PC boots into UEFI/EFI or BIOS environment, perform the following steps:-
Step 1. Switch on the computer or laptop and log in to your account.
Step 2. Open Windows installation drive (usually it’s “C” drive).
Step 4. Under the Panther folder, locate the file setupact and open it will a notepad/WordPad.
Step 5. In the file setupact, look for Detected Boot Environment.
Once you complete the above steps, you can quickly determine if your PC supports UEFI/EFI on Windows 10/8.
