How to Enter BIOS on Any Laptop Brand (HP, Dell, Lenovo, ASUS, Acer)

-


 

Need to change the boot order, install Windows from a USB drive, enable virtualization, or troubleshoot your computer? In all these situations, you will need to access the BIOS.

Many users struggle to enter BIOS because different laptop manufacturers use different keys. Pressing the wrong key often causes Windows to boot normally instead of opening the BIOS settings.

In this guide, you'll learn how to enter BIOS on popular laptop brands including HP, Dell, Lenovo, ASUS, Acer, Toshiba, Samsung, and more.

What Is BIOS?

BIOS stands for Basic Input/Output System.

It is firmware stored on your computer's motherboard that initializes hardware components before Windows starts.

Newer computers may use UEFI (Unified Extensible Firmware Interface), which is a modern replacement for traditional BIOS.

Although the interface may look different, people commonly refer to both as "BIOS."

Why Would You Need to Enter BIOS?

You may need BIOS access to:

  • Change boot order
  • Install Windows from a USB drive
  • Enable virtualization (VT-x or AMD-V)
  • Enable or disable Secure Boot
  • Check whether an SSD or HDD is detected
  • Reset BIOS settings
  • Troubleshoot startup problems
  • Enable TPM for Windows 11
