Set up or repair the boot menu on a dual-boot PC
When setting up a PC to boot more than one operating system, you may sometimes lose the ability to boot into one of the operating systems. The BCDBoot option allows you to quickly add boot options for a Windows-based operating system. To set up a dual-boot PC:
Install a separate hard drive or prepare a separate partition for each operating system.
Install the operating systems. For example, if your PC has Windows 7, install Windows 10 onto the other hard drive or partition.
Reboot the PC. The boot menus should appear with both operating systems listed.
If both operating systems aren’t listed:
Open a command line, either as an administrator from inside Windows, or by booting to a command line using the Windows installation media and pressing Shift+F10, or by booting to Windows PE (WinPE: Create USB Bootable drive).
Add boot options for a Windows operating system.
Copy
bcdboot D:\Windows
Reboot the PC. Now, the boot menu will show both menu options.

D answer is correct, because the state of the question is to restore Win2k8 Boot, not Win2k12 as we could do that using C option!
