Attention, Multi-booters....

If you've been re-formatting and re-installing operating systems on two or three or more partitions of your hard-drive, and have ended up with only the old original white wording on a black background in your opening Boot Screen, and you would prefer to have the newer Windows Boot Manager screen with its nice light blue background and white text for its selections, and what you've tried so far with Command Prompt in Admin mode hasn't worked, for some reason, then try this:-

Download and install the latest free version of EasyBCD from here and then navigate to its "Useful Utilities" (in the next window) and choose "EasyBCD Power Console". Open that, (looks like a mini-CMD Prompt) and at the blinking cursor, type in "BCDBoot C:\Windows" and press "Enter". - The very same thing you tried in your regular Command Prompt, but it didn't work there. However, for some mysterious reason known only to the folks at Neosmart, it works here! The next time you do a Reboot (which should be right away!) you'll get your desired modern GUI for the Boot Screen selections.
