Error while installing Hackintosh

Hi, after million issues, I'm stuck on a point that I cannot figure out.

While installing el capatain, i get this error:

OS X could not be installed on your computer.
File system verify or repair failed.
Quit the installer to restart your computer and try again.


The partition where I'm trying to install OS X is formatted with Disk utility.
I don't know how to figure it out, thanks, help me.
