Accessing the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is a critical step for users looking to modify their computer’s fundamental settings. Whether it’s overclocking the CPU, enabling virtualization, adjusting memory speed, or setting up TPM encryption, entering the BIOS is the gateway to these advanced configurations. However, the process of accessing the BIOS varies significantly across different computer manufacturers and models.
BIOS Key by Manufacturer

Additional Notes:
- This table is a general guideline and may not apply to all models.
- The specific BIOS key for your computer can be found in the user manual or on the manufacturer’s website.
- You may need to press the BIOS key repeatedly during the boot process.
- Some manufacturers use a combination of keys to access BIOS.
- If you are still having trouble accessing BIOS, you can contact the manufacturer’s support for assistance.
Additional Information
Why Do Certain Manufacturers Vary?
Certain manufacturers like iBuyPower, CyberPowerPC, Skytech, NZXT, Digital Storm, Origin, etc. use various motherboard makes & models in their systems. The most common option is the F2 key but again, it can vary. Because of this, you have to look up the BIOS key combination for the motherboard model you have, then reference the chart.
Sometimes you can also guess the right key by trying the most common options:
The Most Common BIOS Keys
| BIOS Key |
|---|
| F2 |
| DEL or F2 |
| DEL |
| F2 or F12 |
| ESC or F10 |
| F10 |
| F2 or Fn + F2 |
As you can see, the most common BIOS key is F2, followed by DEL or F2 and DEL. F2 or F12, ESC or F10, F10, and F2 or Fn + F2 are less common, but still used by some manufacturers.
Some people like pressing and holding the BIOS key immediately after pressing the power button while others like tapping the key repeatedly. You want to make sure you don’t miss the time window to enter the BIOS so be mindful of that. Tapping the key can sometimes cause a keyboard fault error (a good thing) which may give you a prompt to enter the BIOS. If one of the common combinations doesn’t work, power off and move on to the next.
Understanding BIOS and Its Importance
The BIOS is the firmware your computer uses to initialize hardware during the boot-up process. It’s essential for setting up the system’s basic functions and managing data flow between the computer’s operating system and attached devices like the hard disk, video adapter, keyboard, mouse, and printer.
Common Methods to Access BIOS
There are several ways to enter the BIOS, but the most straightforward method is by pressing a specific key or a combination of keys during the boot-up process. This key varies depending on the manufacturer and sometimes the model of the computer.
BIOS Access Keys for Major Manufacturers
Here’s a quick guide to the BIOS keys used by major computer brands:

Challenges in Accessing BIOS
In some cases, especially with newer and faster computers, the POST (power-on self-test) process may complete so quickly that it becomes difficult to press the BIOS key in time. Additionally, some systems may not recognize input from a USB keyboard during POST, requiring either a PS2-style keyboard or a different approach to access the BIOS.
Alternative Methods to Access BIOS
If you’re unable to use the BIOS key, there are other methods to access the BIOS settings:
- Through Windows’ Advanced Startup: In Windows 10 and 11, you can navigate to the Advanced Startup section in the Settings and use the “Restart now” option under the Advanced startup header. This will reboot your computer and provide an option to enter UEFI Firmware Settings.
- Using a Linux Command: For Linux users, typing “sudo systemctl reboot –firmware” in the command prompt can reboot the system into BIOS settings.
Emergency Methods to Access BIOS
In situations where the operating system fails to boot, the system will typically pause and offer an option to enter the BIOS. Additionally, using an emergency boot disk like a Windows install disk can help access the BIOS. In extreme cases, causing a system halt by unplugging the primary storage drive or overloading the keyboard buffer at startup can force the system to offer BIOS access.
Caution While Modifying BIOS Settings
It’s crucial to exercise caution when changing settings in the BIOS. Incorrect configurations can lead to hardware compatibility issues or system instability. Always ensure you understand the implications of the changes you are making.
Staying Informed and Prepared
Keeping abreast of the specific ways to access and navigate your computer’s BIOS is vital for troubleshooting, upgrading, or optimizing your system’s performance. Whether you’re a seasoned tech enthusiast or a casual user, understanding these fundamental aspects of your computer’s operation can significantly enhance your experience and capability in managing your device.
