How do you access BIOS setup on different types of computers? (2024)

You may need to access BIOS setup for various reasons, such as troubleshooting, upgrading, or optimizing your computer. For example, you may want to change the boot order if you want to boot from a different device, such as a USB flash drive or a DVD. You may also want to enable or disable certain features, such as virtualization, secure boot, or legacy mode. Additionally, you may want to adjust the performance and power settings of your CPU, RAM, or fan. However, you should be careful when changing BIOS settings, as some of them may affect the stability and functionality of your computer.

The method of accessing BIOS setup on Windows computers may vary depending on the manufacturer, model, and version of your computer. However, a common way to enter BIOS setup is to press a specific key or a combination of keys during the startup process, before the Windows logo appears. The key or keys may differ depending on your computer, but some of the most common ones are F1, F2, F10, F12, Del, or Esc. You may also see a message on the screen that tells you which key to press to enter BIOS setup. Alternatively, you can access BIOS setup from Windows 10 by going to Settings > Update & Security > Recovery > Advanced startup > Restart now > Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.

Unlike Windows computers, Mac computers do not have a BIOS, but a similar firmware called EFI (Extensible Firmware Interface). To access EFI setup on Mac computers, you need to press and hold the Option key while turning on or restarting your computer. This will bring up the Startup Manager, which allows you to choose which device to boot from. You can also access other EFI settings by pressing and holding other keys during startup, such as C for booting from a CD or DVD, N for booting from a network server, or D for running diagnostics.

The method of accessing BIOS setup on Linux computers is similar to that of Windows computers, as you need to press a specific key or a combination of keys during the startup process. However, the key or keys may vary depending on the distribution, the hardware, and the bootloader of your Linux computer. Some of the most common keys are F2, F10, F12, Del, or Esc, but you may also need to press other keys, such as Tab, Shift, or Ctrl. You may also see a message on the screen that tells you which key to press to enter BIOS setup. Alternatively, you can access BIOS setup from some Linux distributions by using commands or tools, such as grub-reboot, efibootmgr, or systemd-boot.

The features and functions of BIOS setup may vary depending on the computer manufacturer, model, and version. The Main category typically displays basic information about the system, such as the time and date, the BIOS version, the processor type and speed, and the memory size and speed. You can also set a password to protect your BIOS settings from unauthorized changes. The Boot category allows you to change the boot order and priority of your devices, as well as enable or disable features such as fast boot, secure boot, or legacy mode. The Advanced category provides more control over the configuration and performance of your hardware components, such as the CPU, the chipset, the memory, the graphics card, the fan, and the peripherals. You can also enable or disable features such as virtualization or hyper-threading. The Security category allows you to set various security options for your computer and manage your trusted platform module (TPM). Finally, in the Exit category you can save or discard your changes and exit BIOS setup or load default settings or restore previous settings if needed.
