This error typically occurs when your computer is unable to find a bootable device to start the operating system. But don't worry, we've got you covered! In this article, we will explain what causes this error and provide you with step-by-step instructions on how to fix it and get your computer up and running again.

What Causes the "Selected Boot Device Failed" Error?

Before we dive into the solutions, let's first understand why this error occurs. The most common causes of the "Selected Boot Device Failed" error include:

• Incorrect boot order in BIOS settings
• Corrupted or missing boot files
• Issues with the hard drive or storage device
• Faulty or disconnected cables

How to Fix the "Selected Boot Device Failed" Error

Now that we know what causes the error, let's explore the solutions to fix it:

1. Check the Boot Order in BIOS Settings

The first thing you should do is check the boot order in your computer's BIOS settings. The boot order determines the sequence in which the computer looks for bootable devices. To access the BIOS settings, follow these steps:

1. Restart your computer.
2. During the startup process, look for a message that says "Press [key] to enter Setup" or something similar. The key to press varies depending on your computer's manufacturer, but it is usually one of the function keys (e.g., F2, F10, or Del).
3. Once you are in the BIOS settings, navigate to the "Boot" or "Boot Order" section.
4. Ensure that the device you want to boot from (e.g., hard drive, SSD, or USB) is listed as the first boot device. If it's not, use the arrow keys to move it to the top of the list.
5. Save the changes and exit the BIOS settings. Your computer will restart.

2. Repair Corrupted or Missing Boot Files

If the boot files on your computer are corrupted or missing, you can use the Windows Recovery Environment to repair them. Here's how:

1. Insert your Windows installation media (e.g., DVD or USB) and restart your computer.
2. During the startup process, press any key to boot from the installation media.
3. Select your language preferences and click "Next."
4. Click on "Repair your computer."
5. In the next screen, select "Troubleshoot" and then "Advanced options."
6. Choose "Startup Repair" and follow the on-screen instructions to repair the boot files.
7. Once the repair process is complete, restart your computer.

3. Check the Hard Drive or Storage Device

If the above solutions didn't resolve the issue, it's possible that there is a problem with your hard drive or storage device. Follow these steps to check for any issues:

1. Restart your computer and enter the BIOS settings.
2. Navigate to the "Storage" or "Drives" section.
3. Check if your hard drive or storage device is detected by the BIOS. If it's not, there may be a problem with the device or its connection.
4. If the device is detected, try changing the SATA mode from AHCI to IDE (or vice versa) and see if that resolves the issue.
5. If none of the above steps work, you may need to replace the hard drive or seek professional help.

4. Check Cables and Connections

Loose or faulty cables can also cause the "Selected Boot Device Failed" error. Follow these steps to check the cables and connections:

1. Turn off your computer and unplug all cables connected to it.
2. Open the computer case and locate the cables that connect the hard drive or storage device to the motherboard.
3. Ensure that the cables are securely plugged in at both ends.
4. If you have spare cables, try replacing them to rule out any cable issues.
5. Close the computer case, reconnect all cables, and start your computer.

By following these steps, you should be able to fix the "Selected Boot Device Failed" error and get your computer back up and running. If the issue persists, it is recommended to contact a professional technician for further assistance.

Conclusion

The "Selected Boot Device Failed" error can be frustrating, but with the right troubleshooting steps, you can resolve it and boot up your computer without any issues. Remember to check the boot order in BIOS settings, repair corrupted or missing boot files, check the hard drive or storage device, and ensure all cables and connections are secure. If you're still facing the problem, don't hesitate to seek professional help.
