Use the latest firmware interface, the Unified Extensible Firmware Interface (UEFI).
UEFI offers new features including faster startup and improved security. It replaces BIOS (basic input/output system).
More recent Surface devices use a new UEFI called Surface UEFI. For more info, including info about which specific devices use it, see How to use Surface UEFI.
For Surface Pro, Surface Pro 2, Surface Pro 3, and Surface 3
Important: Under normal circumstances, there’s no need for you to change UEFI settings. If you change these settings, you risk the security of your Surface. But if you ever need access to the firmware features of your Surface, here's the basic info:
What firmware features can I use?
You can access the following firmware features on any Surface Pro model or Surface 3:
Secure Boot Control. Secure Boot technology blocks the loading of uncertified bootloaders and drives.
