How to figure out boot disk from bcdedit?

Question

I have Windows Server 2008 R2 software mirror.

I boot from volume c:.

When i use:

bcdedit 

I can see 3 different "Windows Boot Loader" entries with "device partition=C:". How can I figure out which boot entry is related to which physical disk?

Windows Boot Loader
-------------------
identifier              {77777777-bbbb-bbbb-bbbb-bbbbbbbbbbbb}
device                  partition=C:

osdevice                partition=C:
systemroot              \windows

Solution 1

1. Open a command prompt with administrator privileges.

2. Run the following set of commands:

   DISKPART
   SELECT DISK 0
   UNIQUEID DISK ID=<random_disk_signature>
   

   (<random_disk_signature> is e.g. 1a2b3c4d)

3. Quit DISKPART, but stay in the command prompt.

4. Enter the following commands, one at a time, in the command prompt pressing Enter key after each command:

   bcdboot c:\windows /s c:
   bcdedit /set {DEFAULT.EN_US} device partition=c:
   bcdedit /set {DEFAULT.EN_US} osdevice partition=c:
   bcdedit /set {BOOTMGR.EN_US} device partition=c:
   

5. Close the command prompt.

6. Reboot.

Solution 2

All 3 entries shown in bcdedit output point to same partition and disk.

To find out which partition (and disk) is mapped to c: you can use Windows DiskManagement or diskpart.exe on command prompt.

@ saber tabatabaee yazdi : How should I get boot disk with this ?

[saber tabatabaee yazdi]

i'm confused this is impossible that 3 hard disk set as like this: multi(0)disk(0)rdisk(0)partition(1)\WINDOWS but one of them must known as multi(0)disk(1)rdisk(1)partition(1)\WINDOWS and etc. see this en.wikipedia.org/wiki/NTLDR

fixmbr or fixboot or one of these solve your problem

[rumburak]

I do no want to fix anything as its all fine. I want to know boot disk for each entry.
