How to figure out boot disk from bcdedit?

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:

Open a command prompt with administrator privileges.
Run the following set of commands:
```
DISKPART
SELECT DISK 0
UNIQUEID DISK ID=<random_disk_signature>
```
(<random_disk_signature> is e.g. 1a2b3c4d)
Quit DISKPART, but stay in the command prompt.

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:

Close the command prompt.
Reboot.

@ saber tabatabaee yazdi : How should I get boot disk with this ? – rumburak – 2012-10-30T15:09:25.330

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 http://en.wikipedia.org/wiki/NTLDR

fixmbr or fixboot or one of these solve your problem – saber tabatabaee yazdi – 2012-10-31T06:39:29.053

I do no want to fix anything as its all fine. I want to know boot disk for each entry. – rumburak – 2012-10-31T07:00:48.673

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.
