Just to wrap things up, I did get EASYbcd working. I found an icon that I barely noticed because the program runs in a small window and my SP9 is only 13” anyway. So dual boot is running very well. My 2TB drive has both working partitions at 635Gb each, with the data partition having the remaining space. All my gig files are stored and loaded from the data partition, and both Win installs have equal access. Lastly, I have the three partitions backed up on a 2TB Samsung portable SSD. I am pleased with the overall configuration. Cheers for now.
