Osmc failing to install

I’m new to the raspberry Pi. I installed the raspian wheezy and it worked ok. Using another sd card I loaded osmc from the Pi site. When I power up the Pi I get the rainbow screen and that is as far as it goes. Thought it might be the sd card so I tried the sd card I had raspian on and still the same results. What am I doing wrong?

Probably selected the wrong image for the wrong Pi version
