Are you frustrated with the “Boot Device Not Found” error on your computer? This error can be caused by a variety of factors, including a faulty hard drive, incorrect boot order, or a corrupted operating system. In this article, we will explore the possible causes of the “Boot Device Not Found” error and provide step-by-step solutions to resolve the issue.
Understanding the Boot Process
Before we dive into the solutions, it’s essential to understand the boot process. The boot process is the sequence of events that occurs when you turn on your computer. Here’s a simplified overview of the boot process:
- The computer’s power supply is turned on, and the motherboard is initialized.
- The BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware is loaded into memory.
- The BIOS or UEFI firmware detects the hardware components, including the hard drive, RAM, and graphics card.
- The BIOS or UEFI firmware searches for a bootable device, such as a hard drive or solid-state drive (SSD).
- If a bootable device is found, the BIOS or UEFI firmware loads the operating system into memory.
Possible Causes of the Boot Device Not Found Error
The “Boot Device Not Found” error can be caused by a variety of factors, including:
- Faulty hard drive: A faulty hard drive can prevent the BIOS or UEFI firmware from detecting the boot device.
- Incorrect boot order: If the boot order is set incorrectly, the BIOS or UEFI firmware may not be able to find the boot device.
- Corrupted operating system: A corrupted operating system can prevent the BIOS or UEFI firmware from loading the operating system into memory.
- Loose connections: Loose connections between the hard drive and the motherboard can prevent the BIOS or UEFI firmware from detecting the boot device.
- Failed boot device: A failed boot device, such as a hard drive or SSD, can prevent the BIOS or UEFI firmware from loading the operating system into memory.
Troubleshooting the Boot Device Not Found Error
To resolve the “Boot Device Not Found” error, follow these step-by-step solutions:
Check the Boot Order
The first step is to check the boot order. The boot order is the sequence of devices that the BIOS or UEFI firmware searches for a bootable device. To check the boot order, follow these steps:
- Restart your computer and enter the BIOS or UEFI firmware settings. The key to enter the BIOS or UEFI firmware settings varies depending on the manufacturer, but common keys include F2, F12, and Del.
- Navigate to the Boot tab and check the boot order. The boot order should be set to the device that contains the operating system, such as the hard drive or SSD.
- If the boot order is set incorrectly, change it to the correct device and save the changes.
Check for Loose Connections
Loose connections between the hard drive and the motherboard can prevent the BIOS or UEFI firmware from detecting the boot device. To check for loose connections, follow these steps:
- Shut down your computer and unplug the power cord.
- Open the computer case and locate the hard drive.
- Check the connections between the hard drive and the motherboard. Make sure that the connections are secure and not loose.
- If you find any loose connections, tighten them and reassemble the computer.
Run a Diagnostic Test
A diagnostic test can help you identify any issues with the hard drive or other hardware components. To run a diagnostic test, follow these steps:
- Restart your computer and enter the BIOS or UEFI firmware settings.
- Navigate to the Diagnostic tab and select the diagnostic test option.
- Follow the on-screen instructions to run the diagnostic test.
- If the diagnostic test identifies any issues, follow the on-screen instructions to resolve the issue.
Reinstall the Operating System
If the operating system is corrupted, you may need to reinstall it. To reinstall the operating system, follow these steps:
- Insert the installation media, such as a CD or USB drive, into your computer.
- Restart your computer and enter the BIOS or UEFI firmware settings.
- Navigate to the Boot tab and set the boot order to the installation media.
- Save the changes and exit the BIOS or UEFI firmware settings.
- Follow the on-screen instructions to reinstall the operating system.
Advanced Solutions
If the above solutions do not resolve the issue, you may need to try more advanced solutions.
Use a Bootable USB Drive
A bootable USB drive can help you boot your computer and access the operating system. To create a bootable USB drive, follow these steps:
- Insert a USB drive into your computer.
- Download a bootable USB drive creator, such as Rufus or Etcher.
- Follow the on-screen instructions to create a bootable USB drive.
- Insert the bootable USB drive into your computer and restart it.

The “Boot Device Not Found” error can be frustrating, but it can be resolved with the right solutions. By checking the boot order, checking for loose connections, running a diagnostic test, and reinstalling the operating system, you can resolve the issue and get your computer up and running again. If the above solutions do not work, you may need to try more advanced solutions, such as using a bootable USB drive or a live CD or DVD.
What is the “Boot Device Not Found” error, and what causes it?
The “Boot Device Not Found” error is a common issue that occurs when a computer is unable to locate the boot device, which is the device that contains the operating system. This error can be caused by a variety of factors, including a loose or faulty connection between the boot device and the motherboard, a corrupted boot sector or master boot record, or a misconfigured BIOS or UEFI settings.
In some cases, the error may also be caused by a failing or failed hard drive, a boot device that is not properly installed or configured, or a conflict with other devices connected to the computer. It’s essential to identify the root cause of the issue to resolve it effectively. By understanding the possible causes, you can take the necessary steps to troubleshoot and fix the problem.
How do I troubleshoot the “Boot Device Not Found” error?
To troubleshoot the “Boot Device Not Found” error, start by checking the physical connections between the boot device and the motherboard. Ensure that all cables are securely connected and that there are no signs of damage or wear. Next, enter the BIOS or UEFI settings and verify that the boot device is properly configured and set as the primary boot device.
If the issue persists, try booting the computer in safe mode or using a bootable USB drive to see if the problem is specific to the boot device. You can also try running a diagnostic test on the boot device to check for any errors or issues. Additionally, check the event logs for any error messages that may indicate the cause of the problem. By following these steps, you can identify the root cause of the issue and take the necessary steps to resolve it.
What are the steps to resolve the “Boot Device Not Found” error due to a loose connection?
If the “Boot Device Not Found” error is caused by a loose connection, the first step is to shut down the computer and unplug the power cord. Next, locate the boot device and check the connections to the motherboard. Gently remove any dust or debris from the connectors and ensure that all cables are securely connected.
Once you have verified that the connections are secure, plug in the power cord and restart the computer.
