I have bootcamp installed and decided I needed more space in Windows 7 I used Disk Utility to give bootcamp an extra 20gbs and now Mac OS doesn't show up when I turn my Macbook Air '10 goes to Windows 7 automatically when I boot with no extra size in the partition. All Mac OS files are still there though, do I need to reinstall Yosemite? I have tried command+R while booting it goes to a spinning globe and a timer after it finishes it gives an error and restarts
