How to fix black screen with cursor

Abay HP of that series do this when the HDD can not be accessed. It is possible that you have a failed HDD. Try to enter the BIOS.This should help with accessing that. there see if your computer can "see" the HDD. If it does not, you know it is your drive. If your drive does show up, set the boot order to something like USB or CD. Get a bootable USB or CD (I use Linux Live software on a USB drive) and see if that lets you access the HDD. If not, it's time to replace it as well as your OS.
