    You'll need to boot into Internet Recovery or from a USB flash drive (if you created one) and reinstall OS X from scratch. Attempting to re-size a Boot Camp partition doesn't work. You need to nuke the Windows install and start from scratch with the partition size you want.

    If you are just looking to resize your bootcamp partition then I recommend winclone to back it up (so you don't have to re-install windows).

    As for resizing, if you don't have the recovery partition, enter into the internet recovery and reinstall OS X as mentioned.
