I have been using Yosemite Upgrade Broke Bootcamp as reference for others. You will need to download Testdisk and GPT Fdisk (Gdisk) and start with Testdisk to look for deleted NTFS partition headers.

Please see http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step#A_partition_is_still_missin g:_Deeper_Search for a guide.
