Partition Table Error

Hi,

after an unsuccessfull Bootcamp installation iOS doesn't start any more.

On the display the prohibition sign appears.

I tried to check HDD by using internal recovery tool (CMD+ R).

It says I have to do a repair on volume.

But the repair doesn't solve the problem.

After that I try to reinstall the whole system by automatic internet download.

The needed files are loaded successfully, but the next error is displayed

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

Do you have a backup? The following will erase all your data. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Then re-install the OS.

OS X Recovery (2)

When you reboot, use Setup Assistant to restore your data.
