    Hey guys,

    Got a mid 2009 Macbook pro Yosemite

    Been working perfectly fine, all of a sudden the Mac gets to 50% boot then restarts. I've tried cmd + r just hangs on 50%

    Safe mode, just loops back round to the loading screen

    I've lost the cd so at a loss what to do

    Try cmd-option-r to get the recovery options.

    Sorry it is cmd-r you want

    If it isnt completing then you may have a disk failing/failed.

    You may need to try making a bootable usb stick with the installer file to reinstall, you will need the installer file, Diskmaker X and another mac to make it on.
