You cannot format the OS drive while you are running the OS. You must do this from a boot up and not enter windows. That is why you are seeing the error. Remember a format erases the entire contents of the drive and since the program you are running to format the drive is on that driver you are in effect erasing that program while its running.
What you need to do is put your OS disk into the driver and boot up from it. At the beginning will be an option to choose the partition or drive to install windows on as well as a option to format the drive. This is the point at which you need to format the drive.

Ok, so that makes sense but what about my feeling that on the two previous attempts of reinstallations did not reformat the drive?

unless you specify it normally there will not be a full format. just an over writing of the files.
