When you tried to start a Windows operating system, you may receive the error message Missing Operating System on the black screen. That’s a so annoying error since it will prevent you from entering Windows. Well then, what’s the cause for this error and how can we get missing operating system back? These are what we are going to talk in this post.
Both hardware issues and software failures can make an operating system not found, and here we mainly list the following 5:
1.The basic input/output system (BIOS) does not detect the hard disk that installs Windows.
2.The hard disk failed either physically or logically.
3.Users make inappropriate or incorrect BIOS settings.
4.Windows Master Boot Record (MBR) located on the hard drive is damaged or corrupted.
5.The partition which saves Windows boot files is no longer active or users set wrong partition active.
