Yosemite killed Win 7 bootcamp....

Please test your local Recovery HD using Command+R. It should start without a spinning globe. You can also test Internet Recovery using Command+Opt+R (with a spinning globe) and an ethernet connection.

LOL. I can always use these threads as a reference on my CV. 😉

Very glad to see it work. Please make sure you a TM backup of your OSX side. You can also backup Windows via Windows Backup to an external NTFS partitioned disk.

Hi, I have similar problems with this issue. Can you please help me? I'm really not at all a techy person and I've read a lot of threads on this issue and I just don't understand how to do any of this. I've download Testdisk and GDisk but I don't know what to do from there. I don't want to mess up any of my files so can you take me through this step by step? Sorry if I ask stupid questions because I really don't know anything about computers in general.

Would it be easier if you started a new thread and posted your information there, so it is a bit cleaner?

You seem to very similar issues created by Yosemite.

In your GPT output

The large gap between GPT#3 and GPT#4 is where part of your Windows installation is sitting, but Yosemite modified the entries incorrectly.

Testdisk is used first to locate the 'lost' NTFS header and then Gdisk is used to correct the GPT4 entry.

I suggest you start Testdisk in OS X Terminal as sudo gdisk /dev/rdisk0.

There is a Testdisk step-by-step http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step#Example_problem and you will need to run Deeper Search which can be run once you start with Quick Search. Do not use right/left cursor keys when running Testdisk. Use only up/down and enter to navigate.

I created a new thread here Can't find Bootcamp Partition, can you please respond to it? I took a look at the TestDisk example guide you linked, and I believe I do have the basics down, so I just need to figure out how exactly to locate and correct the GPT4 entry.
