Ethernet cable settings

Hi Campbell,

Thank you for writing to Microsoft Community Forums.

Please reply to the follow questions to get a better understanding on the issue:

• What is the model number of your laptop?
  
• Do you have a yellow exclamation on the network icon after connecting the cat 7 cable?
  

However, you can follow the troubleshooting steps from
Fix network connection issues in Windows.

Also, I suggest you to check the laptop manual or laptop manufacturer to know whether the Ethernet port of your laptop supports cat 7 cable.

Hope it helps.

Check cable connection no bootable device

Is that the complete error message?

This is the normal error message for that:

Check cable connection!

PXE-M0F: Exiting Intel PXE ROM.

No bootable device -- insert boot disk and press any key

There are normally 3 possible reasons for that error.

1. BIOS Boot Order set to Boot to Network: Check BIOS settings for Boot Order.

2. Check cable connections between Motherboard and Hard Drive.

3. Failed Hard Drive.
