Executive Summary:
Dual Boot is up and running on my PC without any issues.

Yes. I have 3 internal drives, 1 SSD and 2 HDDs. Win8.1 resides on the SSD. Each of the 2 HDDs are 1TB WD units. The first of the WD units has four partitions. The third partition on that drive is 500GB and I allocated that partition (drive F:) for Win10TP.

I did download EasyBCD and played around with it after RTFM. As previously noted, The BCD record showed that
Vista was the recorded name. I changed that to
Windows 8.1. Since my original install and updates still resided on drive F:, I decided to employ the Add feature in EasyBCD to add drive F: with the appropriate name, wait for it...
Windows 10 Technical Preview. It added the new record successfully. Saved all the changes and rebooted.
Immediately after the POST and before Windows appeared, the Windows Boot Manager popped up on the black and white screen and asked which O/S boot I wanted. I selected the Win10TP and a message came back that there was corruption in the required boot record for Win10TP.
Then selected the Win8.1 option and it booted fine to that O/S. I then reformatted drive F: and restarted the install of Win10TP using the bootable install DVD created from the downloaded ISO file. The install went fine and on the first restart, the appropriate boot menu options appeared.

Then proceeded to perform the updates. Throughout all the restarts, the above menu appeared. Then downloaded and installed build 9860. This time around the whole download and install process only took 35 minutes. Then performed the Windows Update for the build 9860 environment. With all the restarts, the proper optional boot menu appeared.
At that stage, I restarted and selected Win8.1 from the menu.
Loaded EasyBCD Used the Windows Blue Option menu and changed the default timings to 5 seconds and made Win8.1 the default. Then restarted again.
This time the above boot menu did not appear. What did appeared, right after the POST was the black and white display asking which O/S I wanted. Regardless, I was able to select the desired O/S.
My next test will be to change the default O/S to Win10TP to see if the blue option screen comes back.
Anyway, as the Executive Summary showed... we are up and running, with a slight twist!
for your assistance.
