 The NI roboRIO 2.0 boots from a microSD card configured with an appropriate boot image containing the NI Linux Real-Time OS, drivers, and libraries specific to FRC. There are two ways to create the microSD card -- with the roboRIO :ref:`using the imaging tool <docs/zero-to-robot/step-3/imaging-your-roborio:Imaging your roboRIO>`, or with a laptop and an SD burner application per the instructions on this page.

 .. warning:: Before imaging your roboRIO, you must have completed installation of the :doc:`FRC Game Tools</docs/zero-to-robot/step-2/frc-game-tools>`. You also must have the roboRIO power properly wired to the Power Distribution Panel. Make sure the power wires to the roboRIO are secure and that the connector is secure firmly to the roboRIO (4 total screws to check).
