Finally, got D Drive formatted. That was not smart on my part. When I built PC, I had tech move data & program files to D: so as not to have to reinstall Win 7 from scratch. I moved Programs back over to C: and reinstalled them to get registry right. I moved data (docs, pictures, Data etc) back over to C:. He also moved system partition to D: for some unknown reason.
The computer would not reboot as Sys files had been removed from D: by format process. Thank God for Acronis Recovery disk with bootable media. I have done a recovery which should put D drive back into active status.
I won't try this again and if I ever install an OS upgrade again, it will be a total, fresh, clean install.
Thanks for the attempted help.
