Cannot switch back to OS x after installing windows 8 via bootcamp

Hello everyone,

2014 I have installed windows 8 via bootcamp on my MAC. At the beginning everything was working fine and I could switch between the two operation systems.

However, windows asked me to do recovery partition and after it was done I couldn't switch back any more to OS x.

I wanted just to upgrade windows 8 to windows 10, but I couldn`t via the update option , so I tried via bootable USB with Windows. Moreover, all my tries ended with different errors such as:

Then I have tried first to reinstall OS x with bootable OS x Yosemite and OS x El Capitan, but you can see what have happened:

I also tried to start OS x via the bootcamp control panel, but I couldnt you can see:

Please advice me How I can completely wipe out everything and install new OS x or how I can repair my existent OS x.

Thanks in advance! 🙂

MacBook Air (13-inch Mid 2013), OS X Mavericks (10.9.2)

Use OS X: About OS X Recovery - Apple Support to boot into Internet Recovery and How to install OS X on an external drive connected to your Mac - Apple Support and boot from this external disk. W8 is fairly buggy, you should consider W8.1. Do you have backups of OS X and Windows?

I fixed my problem by recovery of the system via internet. When you restart your MAC you have to hold "Option Key + R" to go in internet recovery mode.

The first 2 tries I have experience some problems with the connection, however, on the 3rd try everything went smooth. Thank you for your help 🙂 Now I am using OS X El Capitan + Windows 10 Pro - everything works great so far 🙂

Very nice. Please create backup os OS X and Windows, and create a Windows System Restore point, for future recovery.
