How to Check if Your PC Supports UEFI/EFI on Windows 11/10/8?

You are probably aware of BIOS (Basic Input/Output System) if you have ever installed or reinstalled Windows operating system on any computer or laptop. We need to change the BIOS settings to enable boot from CD/DVD or USB most of the time. BIOS (Basic Input/Output System) is now outdated, and PC manufacturers are replacing the outdated BIOS (Basic Input/Output System) with the new UEFI (Unified Extensible Firmware Interface).

Your computer or laptop will probably ship with UEFI/EFI if you recently purchased.

Features of UEFI

UEFI comes with more features when compared to the outdated BIOS and solves many BIOS limitations. 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 11/10/8 support UEFI firmware.

Further, I want to let you know that there’s no way to switch from BIOS to UEFI on an existing PC. You have to buy new hardware that supports UEFI. You can choose to install and boot old operating systems that expect a BIOS instead of UEFI. Most UEFI implementations provide BIOS emulation; this shows that they are backward compatible.

You can check PC’s user manual or even find the details on the manufacturer’s website if you aren’t aware of whether your PC is booted into UEFI or legacy BIOS mode. Still, there is easier to find the current boot environment without using third-party tools in Windows 11/10/8.
