What Causes the “Boot Device Not Found” Error?

The "Boot Device Not Found" error indicates that your computer failed to locate the device from which it should boot the operating system.
Let's dive into why this error occurs and what it signifies.

  1. Loose or Faulty Connections: Sometimes the simplest explanation is the correct one. Loose SATA or power cables connecting your hard drive or SSD to the motherboard and power supply can cause the BIOS not to recognize the device.
  2. BIOS Misconfiguration: The BIOS settings play a crucial role in the boot process. If the BIOS is not configured to look for the bootable drive in the correct order, or if changes were made that disrupt its default settings, it can result in this error.
  3. Hard Drive Failure: The storage device itself might be failing. Hard drives and SSDs have a finite lifespan, and their mechanical or electronic components can fail due to age, misuse, or defects.
  4. Corrupted Boot Sector: If the boot sector of the hard drive is damaged or corrupted, the BIOS won't be able to load the operating system, even if it recognizes the hard drive itself.
  5. Operating System Issues: Sometimes, the problem could stem from the operating system’s files being corrupted or improperly configured, preventing a successful boot.

How Do I Find My System Boot device?

You can find your system boot device by accessing the BIOS/UEFI settings of your computer. Navigate to the boot options menu and check which device is listed as the primary boot option. Ensure that the correct device containing the operating system files is selected.

Troubleshooting Steps

  1. Check Hardware Connections: Begin by inspecting all connections between your hard drive and the motherboard. Ensure that cables are securely plugged in to prevent any loose connections, which can trigger the "Boot Device Not Found" error.
  2. Verify BIOS Settings: Restart your computer and access the BIOS setup utility by pressing the designated key (commonly Del, F2, or F12) during startup. Within the BIOS, navigate to the "Boot" or "Boot Order" section and confirm that the correct boot device is prioritized as the first option.
  3. Run Hardware Diagnostics: Utilize built-in diagnostic tools to conduct a comprehensive check of your hard drive and other hardware components. Identifying and addressing any hardware issues is crucial for resolving the "Boot Device Not Found" error effectively.
  4. Attempt Booting from an Alternate Device: If feasible, boot your computer from a different device such as a USB flash drive or external hard drive. This can help determine whether the problem lies with the boot device itself or the computer's internal components.
  5. Address Software Errors: In cases where hardware functions properly, software-related issues may be at fault. Utilize system recovery options or boot into safe mode to diagnose and repair corrupted system files, mitigating the impact of software-related errors.
