Cannot format my PC


Honorable Member
system specs: PC, win 10 Home installed, (upgraded from Win 7. 64 bit OS, x64-based processor. version 1803 OS Build 17134.765.
problem: Win 10 failed; unable to open Defender. Plus, unable to connect to Internet (fibre optic cable is hard-cabled in to the box.)
I have backed up all of my data and apps. Instructions are to insert Win 7 into my CD drive. shut down PC. Restart. I did not get a request to strike any key etc. error message 'Win could not retrieve info about this disk on this computer'. any advice, please? (Off topic: as my beloved Surface tablet is going through meltdown (screen burnout due to over-heating).
''the horror'', etc,
