Many Windows 8 users are facing the problem in which they suddenly see a horrific black screen and an error message on it saying “Operating System Not Found”. This problem is mostly related to Hard Drive/BIOS malfunctioning, some system partition is not active, BIOS (computer input/output) does not detect hard disk or Hard Disk is corrupted.
