I just got a Raspberry Pi 3 and am having trouble booting it up.
I bought a microSD card, and followed this guide to install Ubuntu for it https://developer.ubuntu.com/en/snappy/start/raspberry-pi-2/
However, when plugging the microSD card into the Pi and plug in the power cord (I used this power kit https://www.amazon.com/gp/product/B00MARDJZ4/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1), it's stuck at the screen with the 4 color patches (I left it on for hours). The red light is on, and the other light is orange (yellow?).
I then tried to erase the microSD card with Disk Utility on my Mac to the MS-DOS (FAT) format, and then plugged it into the Pi again to boot up. Nothing happens, the HDMI does not have any output, and only the red light is lit.
I am completely new to this so apologies if this is a noob/ basic question. Any help is appreciated.
EDIT: Thanks to @SteveRobillard suggestion, I am able to get Raspbian working. Still no idea why Ubuntu Snappy instruction is not?
