Mac book pro won’t start properly. After pushing the power button a grey and white screen with the apple logo comes up. There is a spinning wheel and bar at the bottom. The bar will fill about 27% and the screen goes black. Thanks

What version of macOS is being used?
See if you can boot into Safe Mode. If you cannot boot into Safe Mode, then try booting into Recovery Mode (Command + R). If you still have issues, then try booting into Internet Recovery Mode (Command + Option + R) to bypass the local boot drive.
When the screen goes black is the laptop still running? Have you tried connecting an external display?
