I am a little late in the game but I am building my first RPi 2 B machine.
Background: I do not have access to a SD card adapter so I am not able to insert my micro SD into my laptop to download/mount an operating system.
Question: Is it possible to load an operating system via another computer and an ethernet connected Raspberry Pi with a micro SD card inserted into it?
I can get an adapter tomorrow but really wanted to get started tonight.
