How to Enter BIOS | How to Access BIOS

The steps to access BIOS can vary depending on your computer's manufacturer and model, (see BIOS hotkeys) but generally, you can follow these steps to enter a system BIOS:

  1. Start or restart your computer.
  2. As soon as the computer starts, look for a message on the screen that tells you which key to press to enter the BIOS setup.
  3. Press the key as soon as you see the message to enter the BIOS setup. If you miss the message or are not sure which key to press, you can try pressing the F2, F9, F10, F11, F12 or Del key repeatedly as the computer starts up.
  4. Once you have successfully entered the BIOS setup, you can navigate through the options using the arrow keys on your keyboard. The exact options and settings available will vary depending on your computer's manufacturer and model.
  5. When you're finished making changes, save your settings and exit the BIOS setup. To do this, look for an option to "Save and Exit" or "Exit and Save Changes" and follow the on-screen prompts.

You should be aware that making some changes to the BIOS setup can be risky and should always be done with caution. In general, it is recommended to only make changes if you know what you're doing. Also be sure to take note of all the changes you make as you make them so that you can later reverse or revert any BIOS changes, if necessary.
