Cannot load macOS installer

I have an on-going problem with my Mac PC for couple of days now. I cannot get it to start no matter what I do. The error message I’m getting says “the macOS installer could not be loaded.” I am using High Sierra 10.13.3 and if anyone knows the solution to my problem, I would be forever grateful!
