Dual boot - Win 8 does not boot after unsuccessful EasyBCD run

If the Windows partition is still intact, but the bootloader is confused, do the following:

- acquire the CD or USB stick with Win 8 recovery tools, any Win 8 PC can create one, but the machine must be 32-bit or 64-bit like the "broken" one.

- boot from this media drive (maybe you need to modify bios boot priority first)

- reach the command prompt

- execute : bootrec /rebuildbcd

-The program will conclude if it finds an installed windows partition. Follow instructions in the prompt.
