The boot menu lets you choose which device to start your computer from, and the trick is tapping the right key (usually F12 or Esc) repeatedly as your PC turns on.
One wrong tap at startup sends you straight into the operating system, leaving you to guess if your PC even has a boot menu. This guide explains how to enter boot menu on any computer, lists the exact key for every major brand, and covers the failsafe Windows method that works when the key doesn’t.
What Exactly Is The Boot Menu?
A boot menu is a startup screen that lets you override your regular boot sequence and pick a specific device to start from — usually a USB drive or a DVD. It sits between powering on and loading Windows, and it solves problems that the regular settings can’t reach. Whether you need to install a fresh OS, run a memory test, or recover a crashing system, the boot menu is the quickest way there.
Boot Menu Keys By Manufacturer
The biggest hurdle isn’t what to do, but which key to press. Below is the standard boot-menu key for the most common computer brands. Press the key repeatedly (don’t hold it down) as soon as the logo screen appears.
| Manufacturer | Boot Menu Key | Notes |
|---|---|---|
| Dell | F12 | Tap firmly once per second during the Dell logo |
| Lenovo | F12, F11, Esc, Del | Model-dependent; try them in order if you are unsure |
| HP | Esc or F9 | Esc usually brings up the Startup Menu, then F9 opens the Boot Menu |
| ASUS | Esc or F8 | Esc on newer models, F8 on older ones |
| Acer | F12 | Must enable the F12 Boot Menu key in BIOS settings first on some models |
Important: The BIOS/UEFI setup key (often Del or F2) is not the same as the boot menu key. The setup key opens the firmware configuration screen, while the boot menu key lists bootable devices.
How To Time The Key Press Correctly
Modern PCs boot so fast that you often have less than two seconds to catch the window. Use this sequence to guarantee you hit it:
- Start with the computer completely shut down.
- Plug in your bootable USB or insert your DVD now.
- Press the power button.
- Immediately start tapping the boot menu key — once per second.
- Keep tapping until the boot menu appears. If the Windows logo loads, you missed the window. Shut down and try again with a faster tap.
What If The Key Still Doesn’t Work?
If your keyboard doesn’t respond during startup, Fast Boot is enabled, or you simply can’t find the right key, Windows itself can launch the boot menu from the desktop. This is the most reliable route because it doesn’t rely on timing.
Method 1 — Shift + Restart. This is the fastest backup plan. Hold down the Shift key on your keyboard, then click the Restart option in the Start menu or sign-in screen. Your PC will reboot directly into the advanced startup environment. From there, go to Troubleshoot > Advanced options > UEFI Firmware Settings > Restart. This gets you to the motherboard firmware, where you can change the boot order permanently.
Method 2 — Settings Menu. Open Settings > System > Recovery (Windows 11) or Settings > Update & Security > Recovery (Windows 10). Next to Advanced startup, click Restart now. Your PC will reboot into the Choose an option screen. Select Use a device to see the boot menu directly.
Method 3 — Command Prompt. If you prefer command-line tools or are already troubleshooting in the terminal, open Command Prompt as an administrator and type: shutdown /r /o /f /t 00. This forces an immediate restart into the advanced boot options screen, giving you access to boot from a device or enter firmware settings.
Three Ways To Enter The Boot Menu (Quick Reference)
| Method | Best For | Action |
|---|---|---|
| Startup Hotkey | Fastest access; single-use boot from USB | F12, Esc, F11, F9, Del (varies by manufacturer) |
| Shift + Restart | When the keyboard isn’t working at startup | Hold Shift + click Restart |
| Settings > Recovery | When you are already logged into Windows | Click Restart now under Advanced startup |
Common Mistakes That Keep The Boot Menu Hidden
A few simple errors can make the whole process fail:
- Pressing too late. Once the OS starts loading, the keyboard shortcut is ignored. Turn off the system completely and tap the key immediately after pressing Power.
- Holding the key down. Tapping firmly at a steady beat (once per second) is more reliable than holding the key.
- Using the wrong key for the model. Check the table above. The BIOS/UEFI setup key (often Del or F2) is not the same as the boot menu key.
- Fast Boot is enabled. Some modern motherboards bypass the startup screen so quickly that key presses are missed. Disable Fast Boot in the UEFI settings, then try again.
- Forgetting to plug in the media first. The boot menu will show your connected drives; if your USB isn’t plugged in, it won’t appear as an option. Plug it in before pressing Power.
- Surface devices. Microsoft Surface tablets and laptops use a completely different method. You need to hold the Volume Up button, then press and release the Power button (while still holding Volume Up). This is not a standard boot-menu key.
Knowing how to enter the boot menu saves time whether you’re upgrading hardware, troubleshooting a crash, or installing a lightweight Linux distro. Start with the specific key for your manufacturer, tap it immediately at power-on, and if that fails, use the Shift + Restart method to guarantee access.
