I have an E5071B ENA RF Network Analyzer.
The system doesn't boot up. I took a picture of the display to show the error messages.
I thought the HDD has some issues so I replaced the harddrive with an empty harddrive, The error messages changed and I only get the following error messages:
PXE-E61: Media test failure, check cable.
PXE-M0F: Exiting Intel Boot Agent.
Operating system not found
I took picture of both errors
