Cause:
Here is a list of common reasons that can trigger the error mentioned above. Understanding these potential causes will help you identify what might be wrong with your computer:
- Recent Hardware or Software Change: This is one of the most common reasons for encountering the above error. Have you recently installed or made changes to your computer’s hardware, such as RAM, HDD/SSD, Processor, or Motherboard? If yes, the appropriate driver might not have been loaded correctly, leading to the error message.
- Corrupted Master Boot Record: The Master Boot Record (MBR) is a critical file for the Windows operating system. It instructs your computer to verify hardware, software, and drivers before launching the OS. If this file becomes corrupted, Windows may fail to start, triggering the “Windows failed to start” error.
- Corrupted or Missing System Files: Incompatible drivers, software installations, or virus/malware attacks can cause some system files to go missing or become corrupted, preventing your computer from booting up properly.
- Incomplete Installation of Windows Updates/Upgrades: Improperly shutting down your computer during an update installation or Windows upgrade can also lead to the above error.
- Faulty cable connection: If the cable connection between hard drive and motherboard is faulty, you may receive the above error.
These are some of the common causes that can prevent Windows 11/10 from loading correctly, resulting in startup issues. To resolve the “Windows failed to start” error, you can apply the troubleshooting methods mentioned below.
