How to Configure Surface Book UEFI/BIOS Settings

Since the first generation of Microsoft Surface Pro and Surface 3, Microsoft has implemented custom BIOS firmware on those devices to support required hardware features and securities.

With Surface Pro 4, Microsoft has created its own UEFI firmware for newer devices. This new firmware is called Surface UEFI, which is currently used on newer devices, including Surface Go, Surface Book, and Surface Studio.

This article will teach you how to get to the Surface Book UEFI settings. You will also learn how to configure the UEFI settings to improve the device security, check your device information, and more.

Protecting UEFI settings with a password

You can prevent others from changing your UEFI settings by setting an Administrator Password in UEFI settings. To do that:

  1. Enter Surface UEFI settings as per the instructions above.
  2. Go to the Security section below:
    Surface Book UEFI > Security
  3. To set the UEFI password, click on the Add or Change button, and you will see the following requirements:Surface Book UEFI > Add Password
  • You will need to enter a password in the box with your keyboard or the on-screen keyboard with the following criteria:
    • Minimum Length: 6 characters
    • Maximum Length: 128 characters
    • It may contain a combination of letters, numbers, and special characters.
  • If you have set the password before and want to remove it, leave the password box blank.
Note If you enter the administrator password incorrectly three times, you’ll be locked out of the UEFI. Restart your Surface to enter the password again.

Important If you set a password for the UEFI, record it in a safe place. If you forget the password, you won’t be able to access the UEFI settings. You can only reset the administrator password from within the UEFI.

What is Secure Boot Control?

The Secure Boot is a technology that blocks the loading of uncertified bootloaders and drives. It helps to prevent your Surface from being loaded with unauthorized operating systems and malicious software applications.

If you desire to install other operating systems like Ubuntu or other Linux distributions, you may need to turn off this feature in the UEFI settings above.

What is a Trusted Platform Module (TPM)?

Surface Book UEFI > What is TPM?

The Trusted Platform Module (TPM) technology significantly advances BIOS in hardware-based security features. It is a specialized chip that stores RSA encryption keys specific to each Surface device for hardware authentication.

The TPM technology is a requirement of BitLocker disk encryption. The TPM helps you encrypt/decrypt the entire disk without requiring complex long passphrases. It means the encryption and decryption keys are stored within the TPM chip. So, your encrypted disks can’t be accessed on other devices.
