5 Conditions That Lead to Operating System Missing
In general, both hardware problems and software crashes can make an operating system not found, and here I essentially list the following 5:
The basic input/output system (BIOS) does not detect the hard disk that installs Windows. The hard disk failed either physically or logically. Users make improper or incorrect BIOS settings. Windows Master Boot Record (MBR) found on the hard drive is damaged or corrupted. The partition which saves Windows boot files is no longer active or users set the incorrect partition active.
