How to Enter BIOS?

Jul 31, 2014

Do you need to change your boot device or set your system clock? The BIOS is the place for you.

The BIOS controls all of the low-level functions of your PC, and you'll need to access it if you want to make any changes. Accessing the BIOS varies from computer to computer, but the basic process is the same. Follow this guide to learn how.

1. Reboot your computer. Since the BIOS controls your system’s most basic functions, you have to access it before Windows loads.

2. Immediately after starting or restarting your computer, you can try holding down one of the above keys to bring up the BIOS screen during the startup process. If you prefer to avoid the trial and error method, look closely at the startup screen for a message that says, "Press the [key] to enter Setup." If you don’t hit the key in time, Windows will load and you will have to reboot and retry.

3. Navigate the BIOS. Once you have loaded the BIOS, you can use your keyboard to navigate the menus. Your mouse will most likely not be working. You can use the BIOS to change the basic settings for your hardware.

4. Use the Advanced Boot option for Windows 8 computers. If you are using Windows 8, you’ve probably noticed that your computer’s boot sequence is too fast to hit the Setup key. Because of this, Windows 8 allows you to boot into an Advanced menu. You have to perform this action within Windows.

Open the Charms bar and click the Settings button.

Click the Power button.

Hold the Shift key and click Restart.

Click “Troubleshooting” and then “UEFI Firmware Settings”.

This will allow you to change your UEFI settings, which are similar to your BIOS settings.
