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

7What is Trusted Platform Module (TPM)?

Surface Book UEFI > What is TPM?

The Trusted Platform Module (TPM) is a technology that provides a major advancement over 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 to encrypt/decrypt the entire disk without requiring your complex long passphrases. It means that the encryption key and decryption key are stored within the TPM chip. So your encrypted disks can’t be accessed on other devices.
