Your U1 Samsung uSD is enough for normal use, and yes, after all you did to the uSD card just power on N2. Take care for initial install not to have any USB drive inserted, as then sometimes the install procedure does not start. Then you need to power off/on the box to start install...

Also, the safest way for me to successfully burn the image file to uSD card is via Etcher. It is the only program that NEVER failed me. With all others I sometimes had problems/errors...
