Windows bootcamp partition gone after upgrade Yosemite

Please run Testdisk with

sudo testdisk /dev/rdisk0

Please see Yosemite Upgrade Broke Bootcamp as a reference on using Testdisk Deeper Search.

The Gap between GPT#3 and GPT#4 indicates the Yosemite disease. 😉

Select the EFI GPT and continue.

Can you post images using an external image sharing service, like IMGUR? Discussions images break arbitrarily an dI cannot see them.

More than likely you will end up with a Deeper Search.

This looks like the first screen with what you currently have. Select the EFI partition and try a Deeper Search.

Do not use left/right cursor keys in Testdisk, they delete partitions.

You have three entries of MS Data of size 349663225 bytes. Scroll to each one and use "P" to list files. If you see familiar Windows files, post a screen image.

You have only a couple of steps left to finish the recovery.

I would check all three. The two 349663225 with this size are the most likely candidate.

What conclusion can be made from the above output?

This is your EFI partition. You should look in the MS Data entries for familiar files.
