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 !

You do not seem to have a choice. Try the Deeper Search, but be very patient. It takes a while.

No. There is a known bug in this calculation. 655884288/1465149167 is about 45%.

The harddisk (750 GB / 698 GiB) seems too small! (< 1223 GB / 1139 GiB)

Check the harddisk size: HD jumpers settings, BIOS detection...

This is a large list, so the navigation should be carefully done. Do not use left-right arrow/cursor keys. Do not modify any settings in Testdisk, because changes do not work on a Mac. Find the first MS Data entry by scrolling down past the last entry. We are interested in MS Data entries.

For each of these MS Data entries, press 'P' to get a listing of files, press Escape only once to get back to the MS Data entry list from the file system directory listing. Check all of these till you find something similar to the following. This is a allow process, please be patient.
