How do I get it to start up
iMac 21.5", OS X 10.10
Do either of these work?
Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?
CMD+r keys on startup?

Tried both still won’t load
Please describe it exactly what it does when you press the power button.
It comes on with a white screen with an apple symbol and a loading bar which only loads half way and then stops
Most likely cause is a failing Hard Drive.
Well it looks like your HD has failed and must be replaced. I would recommend taking it to your local Apple Authorized Service Provider to be professionaly diagnosed and repaired.
