A ‘No Boot Device Found’ error can be a terrifying message to see on your Windows 10 computer. It typically occurs when your PC fails to find the drive where the OS is installed. Imagine powering up your system, and instead of the familiar desktop, you’re greeted with this error – a roadblock that might leave you puzzled.

Understanding this issue, identifying its causes, and knowing how to fix it is crucial for any Windows user.

Common Reasons for the No Boot Device Error

1: BIOS Settings

Sometimes, settings within the BIOS (Basic Input/Output System) might be configured incorrectly. Think of the BIOS as the brain behind the booting process; if it’s confused, it might not find the right path.

2: Hard Drive Issues

Physical problems with the hard drive or connection issues might prevent Windows from locating the boot device. To get an idea of the process, simply imagine trying to read a book with missing pages.

3: Boot Sequence Error

An incorrectly ordered boot sequence can confuse the system, like following a recipe in the wrong order. The ingredients might be there, but the dish won’t come together.

4: Damaged System Files

Damaged or corrupted system files are like a broken compass guiding your system and if these files are damaged, your computer loses its way.

How to Troubleshoot the No Boot Device Error

1: Checking Connections

  1. Turn off the computer: Ensure that the computer is completely shut down to avoid any electrical issues.
  2. Open the computer case: Locate the hard drive and carefully check the cables connecting it to the motherboard and power supply.
  3. Inspect for physical damage: Check for indications of breakage in the cables or any other issues.
  4. Reconnect the cables: Unplug and then reconnect the cables to ensure their security.
  5. Restart the computer: Power on the computer to see if the problem is resolved.

2: Restarting the Computer

3: Adjusting BIOS Settings

  1. Access the BIOS: Restart the computer and press the BIOS key as it may vary for different systems such as (F2, F10, or DEL) repeatedly until the BIOS menu appears.
  2. Navigate to the boot settings: Use the arrow keys to locate the Boot tab.
  3. Check the boot order: Ensure the correct orientation of the boot order, with the physical memory like a Hard Disk Drive or HDD containing the OS listed first.
  4. Save and exit: Press the appropriate key (usually F10) to save changes and exit the BIOS. The computer will then restart.
