My iMac won't startup, I have tried restarting holding the option key down, clicked the restore disk and on restart I get the apple logo and the progress bar which only gets about half way across, it then restarts itself where the progress bar only goes hard way again. tried resetting the Pram but no luck, It won't start from an external Yosemite boot disk either. Can anyone help please...
