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 !

In this post from you, there is FAT header at this location, which is no longer visible.


There is a 1440 sector gap between Recovery HD and the BC partition. It should be checked for any NTFS information. The dd command on rdisk0s3 skips Recovery HD and looks at the first block in the gap. If there is nothing there, can you dump the 1440 sectors to a file locally and check if there is any NTFS information in these blocks?

You ar e looking for the dd command to show you output similar to the following. The example is from a working Bootcamp partition with a proper NTFS header.


sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C

sofar I understand that the dd command just reads the disk block per block and that you can give an output file with of option...


So I could do the following:


ozeegers$ sudo dd if=/dev/rdisk0s4 bs=512 count=1 of=mbr.bin


to output the results to mbr.bin and then search with what tool ? in this file ?

But how do I specify the 1440 sectors to look for ?


Can you give me more information please ? I can even give you teamviewer access on monday if you have time because I really would like my files back !

Hope your trip is safe.
