Have you ever wondered what happens when you turn on your computer by pressing the power button? Does it just turn on? Incorrect. The simple answer is that your computer’s BIOS handles the booting process. In the past, turning on a Windows PC to access the BIOS required pressing keys because this was a pre-boot environment. However, in recent years, Microsoft has allowed entering the BIOS without restarting the Windows PC.
Whether you want to tweak low-level settings or configure your PC’s hardware functions or enhance security, you can simply enter the BIOS on Windows without rebooting. So find the version of Windows you are running and follow the steps listed below. But before that, let’s understand the basics.
What is BIOS and how does it work?
BIOS stands for Basic Input/Output System and is usually located on the ROM chip on the motherboard. As part of the boot process, it performs hardware initialization using the firmware stored in ROM. The BIOS loads and executes the boot loader (usually the hard drive) when the computer is powered on, which loads and executes the operating system. The BIOS sets up the hardware and starts the operating system.
It does this by providing a set of routines that the operating system can use to perform basic tasks like reading and writing to disk, communicating with the keyboard and monitor, etc. , you must be careful when accessing the BIOS because some options can physically damage your computer.
Is UEFI the same as BIOS?
UEFI stands for Unified Extensible Firmware Interface. It works similar to BIOS, but it stores all boot and initialization information in an .efi file instead of a firmware file. This is a newer type of BIOS that has several advantages over traditional BIOS, such as being faster, more flexible, and easier to update than BIOS. Last but not least, UEFI also supports more hardware types than BIOS.
Note: The BIOS key is not the same for all computer manufacturers. It depends on your computer brand. For example, you need to press F2 on newer Dell systems, while on HP, F10 and ESC is the BIOS key. Therefore, we recommend checking the manual or the manufacturer’s website. The first splash screen you see when you turn on your computer also contains this information. However, not all computer and laptop models display this information.

Enter Windows BIOS without a hitch
BIOS has been an integral part of Windows since its inception. Before Windows 8, the BIOS was difficult to access because each manufacturer had different keys that needed to be pressed. The way things are done has changed dramatically and has become much easier. If you used an earlier version of Windows in the past, what key would you press? Let us know in the comments section.
