bootcamp partition renamed untitled after booting in MacOS

Can anybody please help me ?

I had succesfully installed Windows 10 on my Macbook Pro and ran Windows already several weeks smoothly.

Unfortunately I did not make a backup of my windows files yet.

Today when I booted to El Capitan to connect my iPad to iTunes Windows gave me a message that it needed repair when I tried to reboot to the bootcamp Windows version.

It did not succeed in repairing and only gave my an advanced options menu.

I booted back into MacOS to find that the windows partition was renamed to 'Untitled' and that no files were visible in Finder.

I than ran Disk Utility and selected First Aid on this partition, I thought this was read only to check for disk errors.

Now when booting from Windows it says no operation system available and Disk Utility shows 496 GB empty space on this partition !

I hope not all my files are lost !!

What can I do to repair the bootcamp partition ? I tried to install setup bootcamp files on USB but cannot boot from USB (does not show the USB drive)

thank you !

ok, will do but the other days that I ran testdisk I got the impression that it presented the same windows installation no matter which entry I chose to do a deeper search on ?

Will this be any different since we changed the GPT and MBR ?

thank you

Is it a lost case ?

this is I think how it started, the partition untitled. This is screenshot Disk Utility of this moment. I also think this was the size of my partition...

I am a complete zero when it comes to this stuff but still going to ask dumb questions:

Why does testdisk show partition 4 two times ?
