Windows 10: How do I get to Win 10 from here?

I have my Mom's eMachine Win 7. It quit working, then one day it was back, so I installed Linux over Win 7. I have used a restore disc to get Win 10 on here, but there's no key. How do I get this straightened out? Do I have to just buy Win 10 and start from scratch?

I have home network with separate modem, router, and WAP's. My Windows 7 computer does NOT list the Windows 10 computers on network computer list but the Windows 10 computers network list DO list the Windows 7 computer.

Turned off firewalls, gave permissions, shared drives. Nothing allows Win 7 computer to access the Win 10 computers.

Any suggestions for a fix?

Step 1: I suggest you to run SFC scan,
System File Checkeris a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• Right click on the Start button, click on
  Command Prompt (Admin).
• Type “sfc /scannow” without the quotes and hit
  Enter.
• After the scan, restart the computer and check for the issue.

Step 2: Also, I suggest you to update the display drivers and check.

Steps to Update the Display Adapter driver.

• Press Windows key + Xkey when you are at desktop.
• Select Device Manager.
• Expand Display Adapter.
• Right on the Display Adapter and click on
  Update driver software
