I was away so I could not get that piece of information regarding the format error for the partition. I have since the issue reformatted the whole drive (excluding the recovery for obvious reasons). Reinstalled OS X (El Capitan), ran thru the BootCamp prep to begin installation (note I am now using a DVI cable w/adapter which seems to address the non-responsive display issue). I have keyboard and mouse control and able to navigate the Windows installation GUI. Now here is the moment of truth, after selecting the BootCamp partition and click the format option with no errors as was before previously, aside from the spinning disc (cursor) nothing appears to happen to the partition other then the name of the partition which now omits 'BootCamp'. Upon selecting the partition, I get an error message in the same window stating 'Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information.'
Now I don't think its possible to view the log files in the installation setup here so I don't know exactly how else to do this and more importantly trying to troubleshoot the installation process. Any ideas?
