Whether you want to adjust low-level settings or configure your PC’s hardware functions or increase the security, you can simply enter BIOS on Windows without restarting. So, look for the Windows version you are running on 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 a ROM chip on the motherboard. As part of the boot process, it performs hardware initialization by means of 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 boots the operating system.
It does this by providing a set of routines that the operating system can use to perform basic tasks such as reading and writing to disk, communicating with the keyboard and screen, and so on. However, you must be careful when accessing the BIOS as some options can damage your computer physically.
Is UEFI the Same as BIOS?
A UEFI stands for Unified Extensible Firmware Interface. It functions similarly to a BIOS, but it stores all startup and initialization information in a .efi file instead of a firmware file. This is a newer type of BIOS that has several advantages over traditional BIOS, like being faster, more flexible, and easier to update than BIOS. Last but not least, UEFI also supports a wider variety of hardware than BIOS. Note: The BIOS key is not the same for all computer manufacturers. It depends on your computer’s brand. For example, you need to press F2 on newer Dell systems, whereas on HP, F10 and ESC are the BIOS key. Hence, we recommend checking your instruction 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.

Entering 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 more effortless. If you had previously used an earlier version of Windows, what key would you have pressed?
