To enter BIOS, restart your PC and repeatedly press the specific key your motherboard or laptop brand uses during the very early boot process, before Windows begins loading. The exact key varies by manufacturer, most commonly Delete, F2, F10, or F12, so knowing your specific brand’s key saves repeated trial and error.

Key Takeaways
  • The BIOS key must be pressed during the earliest moment of boot, before Windows loads.
  • Delete and F2 are the most common keys across desktop motherboards.
  • Laptop brands often use different keys, like F1, F10, or a dedicated function key.
  • Windows 11’s Advanced Startup menu offers an alternative entry point.

Method 1: Press the Key During Boot

Restart the PC and immediately begin pressing your brand’s specific key repeatedly, since the window to enter BIOS closes once Windows begins loading. If you miss it, simply restart and try again.

Method 2: Use Windows’ Advanced Startup

  1. Open Settings, then System, then Recovery.
  2. Under Advanced Startup, click Restart Now.
  3. After restart, navigate to Troubleshoot, then Advanced Options, then UEFI Firmware Settings, then Restart.

This method works reliably regardless of timing issues with pressing a key during the brief boot window, and is especially useful if your keyboard press isn’t registering in time.

What If Fast Boot Prevents Entry?

Some systems boot so quickly that the BIOS key window is easy to miss entirely. Using the Windows Advanced Startup method above bypasses this timing issue completely, since it triggers BIOS entry directly on the next restart.

Why You Might Need to Enter BIOS

Tip: if you’re unsure of your exact brand’s key, watch for a brief on-screen prompt during boot, often displaying something like “Press DEL to enter Setup,” which confirms the correct key for your specific system.
