How to use BCDEdit to dual boot Windows installations?


The Question: What are the bcdedit commands necessary to setup dual boot between different
installations of Windows?5
**** Background ****
I recently installed Windows 8 onto a separate hard drive1. Now that Windows 8
in installed I want to dual-boot back to Windows 7.
I have my two2 hard drives:
[Windows partition manager screenshot]
So you can see that I have my two disks, with the partitions containing
Windows:
Windows 7: \\PhysicalDisk0 (partition 03)
Windows 8: \\PhysicalDisk2 (partition 1)
What I'm trying to figure out how is how to use bcdedit to instruct the thing
that boots Windows that there is another Windows installation out there.
Running bcdedit now, it shows current configuration:
C:\WINDOWS\system32＞bcdedit

You need a BCDEdit /set command for configure the boot volume. Then add the
entry to the Windows Boot Manager operating system menu by calling the BCDEdit
/displayorder command.
bcdedit /set {ntldr} device boot
It will identify the other OS' partition or the following command as well
bcdedit /set {ntldr} device partition=C:
The following line makes the entry bootable by adding it to the menu
bcdedit /displayorder {ntldr} /addlast
You can verify that the new entry will appear on the boot menu by running the
command bcdedit /enum ACTIVE and looking for the Windows Legacy OS Loader
entry.
Note: /create command is used to add non-Microsoft OS to boot loader entry.

Regarding your question about "Difference between Windows Boot loader and Boot
manager"
From http://en.wikipedia.org/wiki/Windows_...
Windows NT startup process starts when the computer finds a Windows
boot loader, a portion of Windows operating system responsible for
finding Microsoft Windows and starting it up. On IA-32 or x64
systems, the boot loader is called Windows Boot Manager (BOOTMGR).
Prior to Windows Vista however, the boot loader was NTLDR.

http://www.boyans.net/ is an advanced GUI version of Windows bcdedit utility.
It is the first GUI tool to implement full editing of Windows 7/Vista

Give a try to repair option in the tool.
