Post an image of the verbose output or else nobody can identify the problem.
With Clover, by pressing the space bar can get you different mode/options to boot, just as you've done. Selecting verbose(-v) gives you output while booting instead of just an logo and a progress bar.

You can try connecting an hdmi to a monitor when you are at the black screen, it worked for me. But I don't know how to get to the desktop without this trick.

i tried to reinstall the el capitan,
and upon loading the installer on verbose mode, the process git stuck on this part before it went black screen. i hope someone knows this error. thanks.

I have no idea, but I've encountered the same stuck issue last month. Same error as yours.
And guess what? It's actually not stuck. Mine continued to boot five minutes after that error message. (Service exited with abnormal code)

finally i was able to boot on the installed el capital os x (from 50% boot black screen). what i did is i added some boot args from the default boot arguments of clover.
i added, cpus=1 UseKernelCache=No npci=0x3000 (after an intense googling and guessing).
i was unsure of what i was doing because i really have no idea in programming i only know how to power up a pc and configure a router, but i hope this will help others with the same problem and i hope for the same result.
now i have to know what to do with the post installation process to make everything work.
gotta find now post install guide.

Thank you so much. and i am hoping that i can boot it again next time i turn my laptop on. lol!
