Jan 10, 2015 12:25 PM in response to mmcrocettiby Loner T,Your dd output indicates that the 'lost' NTFS header is sitting in the gap between GPT3 and GPT4 on disk0.
Can you use Bootcamp disk0s4 gone after Yosemite update as a reference (and it has additional links to another thread) and download Testdisk and start the Search for the NTFS partition?
If you need more details, please ask.

Jan 10, 2015 5:18 PM in response to mmcrocettiby Loner T,This is the first part of the recovery procedure. In your case, you have two OS X versions, so standard layout is not usable.
Please install GPT Fdisk (aka gdisk) (http://sourceforge.net/projects/gptfdisk/) if you have not done so yet.
You need to use the following steps. If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8.
Rebuild GPT5 using start/end offsets
- Sudo gdisk /dev/rdisk0
- P (print the full list of parts)
- D (delete)
- 5 (part 5)
- N (new part)
- 5 (part 5)
- 841717760 - Start offset in bytes (start point for Bootcamp part)
- +135055353 (Size offset as opposed to End offset)
- 0700 (Windows part type)
- P (print list of all parts just to see what changes will be made)
- W (Write the new GPT)
- Y (Yes! really write the new GPT)
This will delete and re-write the GPT partition info for /dev/disk0s5.
Reboot. Test that you can see the Bootcamp volume in Finder and see files in the Bootcamp volume.
