On most modern Windows 11 PCs, the firmware settings are UEFI rather than traditional BIOS. You can often open them through Windows Advanced startup, or by pressing the manufacturer’s setup key while the PC starts. Before changing firmware security, boot, TPM, or storage settings, make sure important files are backed up and that you can access your BitLocker recovery key.
Open UEFI Firmware Settings from Windows 11
- Save your work.
- Open Settings.
- Select System.
- Select Recovery.
- Under Advanced startup, select Restart now.
- After Windows enters recovery, select Troubleshoot > Advanced options > UEFI Firmware Settings.
- Select Restart.
The computer should restart into its firmware setup interface when that option is supported.
Use the Manufacturer’s Startup Key
You can often enter firmware setup by pressing a key immediately after powering on the PC. Common examples include F1, F2, F10, F12, Delete, or Esc, but the correct key depends on the manufacturer and model. Check the computer manufacturer’s documentation instead of repeatedly changing firmware settings by trial and error.
Why Is UEFI Firmware Settings Missing?
The option can be unavailable depending on the firmware mode, hardware, device configuration, or how Windows was installed. If it is missing, use the manufacturer’s documented startup-key method.
BitLocker Warning
Firmware and hardware changes can trigger BitLocker recovery. Microsoft says a recovery key may be required when BitLocker cannot automatically unlock the drive after a security or hardware change. Locate the correct recovery key before changing Secure Boot, TPM, boot mode, storage, or other security-sensitive firmware settings.
Do Not Change Settings You Do Not Understand
UEFI controls can affect whether Windows boots, device security, virtualization, storage operation, and hardware compatibility. Record the original setting before changing anything and follow trusted instructions for the specific problem you are solving.
Summary
Use Settings > System > Recovery > Advanced startup, then Troubleshoot > Advanced options > UEFI Firmware Settings. If that option is unavailable, use the startup key documented by the PC manufacturer. Secure your BitLocker recovery key before making firmware changes.
