The Basic Input/Output System (BIOS) is a fundamental component of a computer’s architecture, responsible for initializing and configuring the hardware components during the boot process. Traditionally, accessing the BIOS required restarting the computer and pressing a specific key during the boot sequence. However, with the advancement of technology, it is now possible to enter the BIOS from within the Windows operating system. In this article, we will explore the various methods to access the BIOS from Windows, their advantages, and the potential limitations.
Understanding BIOS and its Importance
Before diving into the methods of accessing the BIOS from Windows, it is essential to understand the role of BIOS in a computer system. The BIOS is responsible for performing a series of checks on the hardware components, known as the Power-On Self-Test (POST), to ensure that they are functioning correctly. It also provides a user interface to configure the system settings, such as the boot order, time and date, and security features. The BIOS is typically stored in a non-volatile memory chip on the motherboard, which allows it to retain its settings even when the power is turned off.
Legacy BIOS vs. UEFI Firmware
In recent years, the traditional BIOS has been replaced by the Unified Extensible Firmware Interface (UEFI) firmware in many modern computers. The UEFI firmware offers several advantages over the legacy BIOS, including improved security features, faster boot times, and support for larger storage devices. However, the methods of accessing the UEFI firmware from Windows may differ from those used for the legacy BIOS.
Key Differences between Legacy BIOS and UEFI Firmware
The main differences between the legacy BIOS and UEFI firmware are:
The UEFI firmware uses a graphical user interface, whereas the legacy BIOS uses a text-based interface.
The UEFI firmware supports secure boot, which ensures that only authorized operating systems can boot on the device.
The UEFI firmware provides faster boot times and improved performance.
Methods to Access BIOS from Windows
There are several methods to access the BIOS from Windows, depending on the type of BIOS or UEFI firmware installed on the system. Here are the most common methods:
The first method is to use the Windows Settings app to access the UEFI firmware settings. This method is available on Windows 10 and later versions.
The second method is to use the Advanced Startup Options to access the UEFI firmware settings. This method is available on Windows 8 and later versions.
The third method is to use a third-party software to access the BIOS settings. This method is available on all versions of Windows.

What is BIOS and why is it important to access it from Windows?
The Basic Input/Output System (BIOS) is a firmware that controls and configures the hardware components of a computer. It is essential to access the BIOS to configure the boot order, enable or disable hardware components, and set up the system clock, among other settings. Accessing the BIOS from Windows allows users to modify these settings without having to restart the computer and enter the BIOS setup manually. This can be particularly useful for users who need to troubleshoot hardware issues or configure their system for optimal performance.
Accessing the BIOS from Windows can be done through various methods, including using the Windows Settings app, the Command Prompt, or third-party software. The method used may vary depending on the version of Windows and the type of computer. For example, on Windows 10, users can access the BIOS by going to the Settings app, clicking on “Update & Security,” and then clicking on “Recovery.” From there, they can click on “Restart now” under the “Advanced startup” section, which will take them to the BIOS setup. Alternatively, users can use the Command Prompt to access the BIOS by typing the command “shutdown /r /o” and pressing Enter.
How do I access the BIOS on a Windows 10 computer?
To access the BIOS on a Windows 10 computer, users can follow a few simple steps. First, they need to go to the Settings app, which can be done by clicking on the Start button and selecting the “Settings” option. From there, they need to click on “Update & Security” and then click on “Recovery.” Under the “Advanced startup” section, they need to click on “Restart now,” which will restart the computer and take them to the BIOS setup. Alternatively, users can use the Command Prompt to access the BIOS by typing the command “shutdown /r /o” and pressing Enter.
Once the computer restarts, users will see a screen with various options, including “Troubleshoot,” “Reset this PC,” and “Advanced options.” They need to click on “Troubleshoot” and then click on “Advanced options.” From there, they can click on “UEFI Firmware Settings” or “BIOS Settings” to access the BIOS setup. The BIOS setup will allow users to configure various settings, including the boot order, hardware components, and system clock. Users can navigate through the BIOS setup using the arrow keys and enter key to select options and save changes.
