Q: internet restore on iMac fails

What I need to do on my iMac is do an internet restore to get back to the original OS for the iMac. I rebooted with command-option-R keys and got into internet restore mode. It got to the point of giving me choice of wifi networks and I successfully authenticated to a wifi network. Then, after a few minutes, I was presented with graphic of circle with line through it. Looks like internet restore had failed. Am I missing something? Do I need to prepare my Mac in some way in order for Internet Restore to work?

    From your Recovery Partition run Disk Utility > First Aid, and tell us what it reports.

    Also, some further specs on your Mac would help. What year is your Mac and what system are you running?

    OK, I ran First Aid in Recovery Mode. Not able to capture all the output because I was in recovery mode. But it found no errors and did not fix anything.

    That is the prohibitory symbol

    About the screens you see when your Mac starts up - Apple Support

    This generally means that it is not finding an OS to boot up from.

    You might try it hard wired to the internet rather than Wi-Fi

    Yes, seems it couldn't find system folder to start up from. Seems like that is a Recovery Mode error or bug. I certainly do have a local valid system folder. I did try hard wired network and that fails too.

    It could be a problem on the server, I'd try again in a few hours, if you haven't already.
