How to Resolve Media Test Failure, Check Cable, No Bootable Device, Boot Device Not Found

Introduction

[Music] Hi guys, this is Dude from Ascetics. In this tutorial, I’ll be showing you how to fix the problem of a missing boot device during Windows startup. First, I’ll be demonstrating this problem on a Lenovo E540 ThinkPad.

Checking for Loose Connections

The first thing you want to check when you encounter this problem is loose connections. Sometimes your laptop might experience shock or vibration that causes the hard disk to come loose from the connector. You can easily access your hard disk on laptops like the Lenovo E540 by opening the compartment under the laptop, cleaning the connectors, and reattaching the disk firmly. This could solve the issue and allow your laptop to boot back into Windows.

Checking BIOS Boot Priority

If checking for loose connections doesn’t solve the problem, the next step is to check your BIOS for boot priority order. Make sure your hard disk is included and placed correctly in the order of priority. Access your BIOS by pressing the designated key during startup (e.g. F1 for Lenovo E540) and navigate to the boot order settings. Ensure that your Windows disk is at the top of the priority order and save changes.

Possible Issues with Cable Connectors

Another possibility for the missing boot device error could be bad cable connectors connecting the disk to the motherboard. To check if this is the case, you can connect another test hard disk to the connector and see if it boots up. If it fails, you may have a broken cable that needs to be replaced.

Conclusion

If none of these solutions work, there may be a more technical issue with tracing the path to your Windows operating system by the BIOS.

Troubleshooting Media Test Failure, Check Cable, No Bootable Device, and Boot Device Not Found Issues

Introduction

Are you facing media test failure, check cable, no bootable device, or boot device not found issues on your computer? Don’t panic! In this article, we will walk you through some troubleshooting steps to help you resolve these common problems.

Media Test Failure

Media test failure is a common issue that occurs when your computer is unable to detect the Ethernet cable or network during the boot process. This can be caused by a faulty network cable, a misconfigured network adapter, or a problem with the network settings on your computer.

To fix media test failure, try the following solutions:

  1. Check the network cable: Make sure the Ethernet cable is securely connected to both your computer and the network device. If the cable is damaged or faulty, replace it with a new one.

  2. Restart your computer: Sometimes, a simple restart can fix the issue. Restart your computer and check if the media test failure problem is resolved.

  3. Update network drivers: Outdated network drivers can also cause media test failure issues. Update the network drivers on your computer to the latest version from the manufacturer’s website.

Check Cable

If you are seeing a "check cable" error message on your computer, it means that there is a problem with the network cable connection. The steps to fix this issue are similar to those for media test failure:

  1. Check the network cable: Ensure that the Ethernet cable is connected properly and not damaged. Replace the cable if necessary.

  2. Restart your computer: Try restarting your computer to see if the "check cable" error message disappears.

  3. Update network drivers: Updating the network drivers on your computer can also help resolve the cable-related issues.

No Bootable Device

When your computer displays a "no bootable device" message, it means that the system is unable to find a bootable operating system on the selected drive. This can happen due to a corrupted operating system, a faulty hard drive, or incorrect boot settings.

To troubleshoot a no bootable device issue, consider the following:

  1. Check boot device order: Ensure that the correct boot device is selected in the BIOS settings. You can access the BIOS by pressing a specific key during the startup process (usually F2, F10, or Del).

  2. Repair the operating system: If the operating system is corrupted, you can try repairing it using the Windows Recovery Environment or a bootable USB drive.

  3. Test the hard drive: Use a disk diagnostic tool to check the health of your hard drive. If the hard drive is faulty, you may need to replace it.

Boot Device Not Found

A "boot device not found" error message indicates that the computer cannot find the selected boot device to load the operating system. This can be due to a disconnected hard drive, corrupt boot files, or a misconfigured BIOS setting.

To fix the boot device not found problem, try the following solutions:

  1. Check hard drive connections: Ensure that the hard drive is properly connected to the motherboard. If it’s a laptop, you may need to open the casing to check the connections.

  2. Rebuild master boot record: You can use the Windows Recovery Environment to rebuild the master boot record (MBR) or GUID Partition Table (GPT) to fix the boot device not found error.

  3. Reset BIOS settings: Resetting the BIOS to default settings can help resolve boot device issues caused by misconfiguration.

Conclusion

By following the troubleshooting steps outlined in this article, you should be able to fix media test failure, check cable, no bootable device, and boot device not found issues on your computer. If the problems persist, it may be best to consult a professional technician for further assistance.

How to Fix Media Test Failure

If you are experiencing a media test failure message on your computer, the issue may be due to a faulty network cable or network card. To fix this, first, check the network cable connection to ensure it is securely plugged in. If the connection looks fine, try replacing the network cable with a new one to see if that resolves the issue. Additionally, you can update the network card drivers by going to the Device Manager and selecting the network card to update the drivers.

No Bootable Device, Boot Device Not Found

If your computer is showing a “No Bootable Device” or “Boot Device Not Found” error message, it could indicate a problem with the hard drive or boot settings. First, check if the hard drive is properly connected by opening the computer case and ensuring all cables are securely connected. Next, access the BIOS settings by restarting the computer and pressing the designated key (usually F2 or Del). In the BIOS settings, check the boot order and make sure the hard drive is listed as the first boot device. Save the changes and restart the computer to see if the issue is resolved.

Conclusion: How to Fix Media Test Failure, Check cable, No Bootable Device, Boot Device Not Found

In conclusion, encountering errors like media test failure, no bootable device, or boot device not found can be frustrating, but with the right troubleshooting steps, you can resolve these issues. By checking cable connections, updating drivers, and adjusting boot settings, you can effectively fix these common computer problems. Remember to always back up your important data before attempting any fixes to avoid potential data loss.
