Hi,
just received a Raspberry pi2 , from a web foreign supplier.
It does not boot, the red and green led are on.
With some investigation, it seems that maybe the uSDCard do not have a linux boot image.
On https://www.raspberrypi.org/downloads/, we have several options:
NOOBS, Raspbian (that i will use to start, since is based on debian).
3x steps to follow:
1. download the image
2. get a SD card adapter to put the uSDCard on the PC
3. get a image writer( win32diskimage or SDFormatter )
or win32diskimager
or sdcard
than unzip the image, choose the img and write to the sd card.
Than put the sdcard on the raspberry and boot.
best
