Accessing your PC’s BIOS can be done at startup with a key like F2 or Del, or through the UEFI Firmware Settings in Windows Recovery.
How to enter BIOS from Windows is a straightforward process with two reliable methods. The first uses a dedicated startup key as your PC boots, and the second goes through the Windows recovery environment. Which route you take depends on your hardware brand and whether Windows loads normally. Both get you to the same firmware settings screen where you can change boot order, enable virtualization, or tweak hardware configuration.
Below are the exact steps for each method, the most common keys by manufacturer, and what to do when the obvious approach fails.
What Is BIOS And Why Would You Enter It From Windows
BIOS (Basic Input/Output System) and its modern successor UEFI (Unified Extensible Firmware Interface) are the low-level software that initializes your PC’s hardware before Windows loads. You enter it to change the boot device order, enable or disable hardware features, adjust memory timing, or troubleshoot a system that won’t start properly. The options inside your firmware screen vary by motherboard manufacturer, but the methods for getting there from Windows are consistent across most modern PCs.
Two Ways To Enter BIOS On A Windows PC
Both methods work on Windows 10 and Windows 11, but your PC must use UEFI firmware for the Windows recovery route to appear. The startup key method works with both legacy BIOS and UEFI systems.
Method 1: The Startup Key — Fastest Route
This is the most direct way: press a specific key during the moment your PC first powers on, before Windows begins loading. HP’s official guidance says to press the designated key repeatedly “as soon as the manufacturer logo appears.”
Steps:
- Save your work and close any open applications — the restart into firmware settings is immediate.
- Restart the PC.
- Watch for the manufacturer logo (HP, ASUS, Dell, Lenovo, etc.) and immediately begin pressing the BIOS key once per second.
- Continue pressing until the BIOS or UEFI setup screen appears, then release.
Common mistake: pressing the key too late, after Windows has already started loading. Press it the instant the screen lights up. Each manufacturer assigns its own key — HP’s guide to entering BIOS setup lists F10, Esc, F1, and F2 as the most common options across its product lines.
ASUS notes that some devices require holding F2 while pressing the Power button on a completely shut-down system. On ASUS gaming handhelds, hold Volume Down and press Power instead.
Method 2: Windows Advanced Startup — No Timing Required
If hitting a key at the right moment is tricky, or you simply prefer a menu-driven approach, use the Windows recovery path. This route takes a few extra clicks but doesn’t require any split-second timing.
Steps:
- Open Settings (Windows key + I).
- Go to Update & Security (Windows 10) or System > Recovery (Windows 11).
- Under Advanced startup, click Restart now. ASUS warns to save unsaved work before taking this step.
- After the PC reboots into the blue recovery screen, select Troubleshoot.
- Choose Advanced options.
- Select UEFI Firmware Settings.
- Click Restart. The system boots directly into your BIOS or UEFI configuration screen.
A faster variant of this method: hold the Shift key while clicking Restart from the Start menu’s power options. This sends you straight to the recovery screen without navigating Settings first.
Common BIOS Keys By Brand
The table below lists the most frequently used keys for major PC and motherboard brands. If your model isn’t listed, try F2 or Del first — those are the industry defaults.
| Brand | Common Key(s) | Notes |
|---|---|---|
| HP | F10, Esc, F1, F2 | Press as the HP logo appears |
| ASUS Desktop | Del, F2 | Hold F2 while pressing Power |
| ASUS Laptop | F2 | Tap repeatedly during restart |
| Lenovo Desktop / AIO | F1, F2, Fn+F2 | Shift+Restart also recommended by Lenovo |
| Dell | F2 | Tap as the Dell logo appears |
| Acer | F2, Del | Desktops lean toward Del; laptops use F2 |
| MSI | Del | Standard for most MSI motherboards |
What If The BIOS Key Doesn’t Work?
If pressing the key produces nothing and Windows loads normally, the most likely cause is timing: you’re pressing too late or too early. Restart and this time start pressing the key the instant the display wakes — before any logo appears. If that still fails, switch to the Windows Advanced Startup method listed above; it bypasses the timing issue entirely.
Another possibility is that your keyboard isn’t recognized during the pre-OS boot phase. USB keyboards connected through a hub or a non-compatible port can be invisible to the firmware. Plug the keyboard directly into a rear USB port (on desktops) or the built-in USB port (on laptops) and try again.
Is Your PC In UEFI Or Legacy BIOS Mode?
Knowing your firmware mode matters because the Windows Advanced Startup route offers a UEFI Firmware Settings option only when the system is running in UEFI mode. If your PC uses legacy BIOS, that button won’t appear. To check which mode you’re in: open System Information (type “msinfo32” in the Start search bar) and look for the BIOS Mode line. It will read either UEFI or Legacy. Legacy systems must rely on the startup key method.
After successfully entering the firmware, ASUS notes that the screen may present a UEFI graphical interface, a simpler Legacy text interface, or their MyASUS in UEFI skin — the layout depends on your motherboard and its settings.
Troubleshooting BIOS Access
The table below covers the most common problems and their solutions.
| Problem | Likely Cause | Fix |
|---|---|---|
| Key does nothing; Windows loads normally | Pressing the key too late | Start pressing the instant the display wakes, before any logo appears |
| UEFI Firmware Settings is missing | PC is in Legacy BIOS mode | Use the startup key method; only UEFI systems show this option |
| Keyboard unresponsive during boot | Keyboard plugged into a hub or incompatible port | Connect directly to a rear USB port on the motherboard |
| Different key works than what I expected | Each brand and model uses its own key | Check the Common BIOS Keys table above or your manual |
| Windows won’t boot at all | Failed update or hardware issue | Startup key is the only option; power on and press the key immediately |
Quick Reference: Entering BIOS From Windows
- For speed: restart and press the manufacturer’s BIOS key (F2, Del, F10, or Esc) as the logo appears.
- For reliability: hold Shift while clicking Restart, then navigate to Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
- If neither works: check your keyboard port, confirm your firmware mode, and consult your brand’s documentation for the exact key.
