Accessing the BIOS on Windows 10: A Step-by-Step Guide
Accessing the BIOS (Basic Input/Output System) on your Windows 10 computer is a straightforward process that can help you make crucial system changes. Whether you're looking to adjust boot order, enable or disable specific features, or troubleshoot hardware issues, this guide will walk you through the process in a clear, concise, and SEO-friendly manner.
Understanding BIOS and UEFI
Before we dive into the steps, it's essential to understand that modern computers use UEFI (Unified Extensible Firmware Interface) instead of the traditional BIOS. However, the process to access both is quite similar. We'll cover both BIOS and UEFI in this guide to ensure everyone can follow along.
BIOS vs UEFI: What's the Difference?
BIOS is an older technology that uses a 16-bit CPU and has a limited amount of memory. UEFI, on the other hand, is a newer, more advanced version that uses a 64-bit CPU and has a larger memory capacity. UEFI also supports a graphical interface, making it easier to navigate than BIOS.

Accessing BIOS/UEFI on Windows 10
Method 1: Restarting Your Computer
This is the most common method to access BIOS/UEFI on Windows 10.
- Click on the Windows Start button and select the Power icon.
- Hold down the Shift key while clicking on Restart.
- Your computer will restart, and you'll see a blue screen with the words 'Choose an option'.
- Click on Troubleshoot.
- Select Advanced options.
- Click on UEFI Firmware Settings (or BIOS Settings, depending on your system).
- Click on Restart to enter BIOS/UEFI.
Method 2: Using the System Configuration Tool
This method is a bit more technical but can be useful if the first method doesn't work.
- Press the Windows key + R to open the Run dialog box.
- Type msconfig and press Enter.
- In the System Configuration window, select the Boot tab.
- Under Boot options, select the checkbox for Safe boot.
- Click on OK and restart your computer.
- Your computer will restart, and you'll be prompted to press a key to enter BIOS/UEFI. The key could be Del, Esc, F2, F10, F11, or F12, depending on your system. Check your computer's manual if you're unsure.
Navigating BIOS/UEFI
Once you're in BIOS/UEFI, you can use the arrow keys to navigate and the Enter key to select an option. Here, you can adjust settings like boot order, enable or disable features, or perform a hardware diagnostic.

Exiting BIOS/UEFI
To exit BIOS/UEFI, you can either save your changes and exit, or discard your changes and exit. If you've made changes, saving them will apply them to your system. Discarding changes will revert your system to its previous state.
Troubleshooting BIOS/UEFI Access Issues
If you're having trouble accessing BIOS/UEFI, there are a few things you can try:
- Check your computer's manual to ensure you're using the correct key to enter BIOS/UEFI.
- Try using the other method outlined in this guide.
- If you're still having trouble, you may need to contact a professional for assistance.
Remember, making changes to your BIOS/UEFI can have serious consequences if not done correctly. Always be careful when adjusting settings, and only make changes if you're sure you understand what you're doing.
