Common BIOS/UEFI Access Keys

Common BIOS/UEFI Access Keys

If you’re in IT support, you already know, sometimes fixing an issue starts before the operating system even loads. Whether you’re troubleshooting boot failures, reimaging a device, or adjusting firmware settings, getting into the BIOS/UEFI is step one.

Here’s a quick-reference guide to help you (or your team) access the boot menu or BIOS across common manufacturers:

🔹 Common BIOS/UEFI Access Keys
• Dell – F2 (BIOS), F12 (Boot Menu)
• HP – ESC or F10 (BIOS), F9 (Boot Menu)
• Lenovo – F1 or F2 (BIOS), F12 (Boot Menu)
• ASUS – F2 or DEL (BIOS), ESC (Boot Menu)
• Acer – F2 or DEL (BIOS), F12 (Boot Menu)
• MSI – DEL (BIOS), F11 (Boot Menu)

⚠️ Pro Tips from the Field:
• Tap the key repeatedly right after powering on—timing is everything.
• For newer systems with fast boot enabled, you may need to access UEFI through advanced startup in the OS.
• Document device models in your environment—some variations exist even within the same vendor.
• External keyboards (especially wireless) can delay input—go wired when troubleshooting.

🛠️ As someone managing end-user computing, infrastructure, and root cause analysis, having quick-hit references like this can save valuable time during incident response and system rebuilds.
