Using bcdedit.exe /enum
To enable the computer to also boot to a second Windows 8 you can use bcdedit.exe with the following command which will copy the current Windows Boot Loader details for Windows 8 to a second record for Windows 7/8 or Server 2012.
bcdedit.exe /copy {current} /d “Second Microsoft Windows 8″
bcdedit.exe will respond with something like the following.
The entry was successfully copied to {…………………………..}.
Using bcdedit.exe /enum to again enumerate through the current entries within the BCD store you’ll see the newly added entry.
Before you can use the newly created Windows boot loader configuration, you’ll need to change the partition for the second Windows 8 using the following two bcdedit.exe commands.
bcdedit.exe /set {……………………………} device partition=D:
bcdedit.exe /set {……………………………} osdevice partition=D:
If you now reboot the system you should now be able to boot into either copy of Windows 8.
