📋 Table of Contents
The error 'PXE-E61: Media test failure, check cable' or similar messages indicates that your computer is unable to connect to a network source or boot device. This issue affects users who rely on PXE (Preboot Execution Environment) for booting their operating system. The frustration of this error stems from the uncertainty and potential data loss associated with not being able to access one's operating system.
This problem can be particularly frustrating, especially when you need to access your computer immediately. However, by following these steps, you should be able to resolve the issue and regain access to your operating system.
🛑 Root Causes of the Error
- The primary reason for this error is a faulty or loose Ethernet cable connection. The PXE ROM checks the network connection before attempting to boot the operating system. If the connection is not stable, it will display the 'Media test failure' message.
- Another possible cause is a malfunctioning network adapter or a misconfigured network settings. In some cases, the issue may be related to the motherboard's BIOS settings or a problem with the PXE ROM itself.
🔧 Proven Troubleshooting Steps
Check and repair the Ethernet cable connection
- Step 1: Locate the Ethernet port on your computer and ensure it is securely connected to both the motherboard and the network device (router, switch, etc.). Check that all cables are properly seated and not damaged.
- Step 2: Try swapping the Ethernet cable with a new one or using a different port to rule out any issues with the current connection.
Update BIOS settings and check for firmware updates
- Step 1: Enter your computer's BIOS setup (usually by pressing F1, F2, or Del during boot) and ensure that the network adapter is set to use PXE as the boot source. Save the changes and exit the BIOS setup.
- Step 2: Check with the manufacturer for any firmware updates for the motherboard or network adapter. Apply any available updates and restart your computer.
💡 Conclusion
If you have tried both methods and still encounter issues, it may be worth seeking further assistance from a qualified IT professional or the manufacturer's support team. Additionally, backing up your data regularly can help minimize potential losses in case of an extended downtime.
