Windows 10 – Converting from Bios to UEFI

Posted on Updated on

As organizations upgrade to Windows 10 there are many opportunities for security and performance improvements. Many of these enhancements rely of functionality that is only available with UEFI firmware as it is required for secure boot which is often a prerequisite for enhanced security features such as Device Guard and Credential Guard. Since Windows 7 did/does not support UEFI, most organizations will need to convert device firmware to UEFI as part of the Windows 10 upgrade. As upgrading to Windows 10 can be a long process, organizations have looked to tools like SCCM and MDT to automate and accelerate the process. Often time performing zero touch installations of hours or through self-service. Converting Bios to UEFI as part of the process ahs been problematic as each device may have different methods for converting and it typically requires visiting the device since the change happens in the before the operating system loads.


Microsoft has just made this problem a little easier to manage. SCCM 1702 introduces the ability to include UEFI conversion as part of a Task Sequence if the device supports it. I’m looking forward to accelerating many Windows 10 migrations with this functionality.
