I recently added a new 2 TB drive to my desktop, and reordered how SATA cables were plugged into my motherboard for my other 3 disks (moving some to SATA 6 gb/s port on motherboard etc). This new drive was just an additional storage drive, the original OS/boot device was still in place, only the SATA port was changed.

I had some issues booting afterwards. Windows would get to loading screen and just spin and spin. I left it for over 24 hours with no changes. I ended up using a Windows 7 dvd and using recovery options. It found a previous system restore point and restored it. After this I was able to boot again.

However, when I go to command prompt and run bcdedit this is my output:


 Windows Boot Manager
 identifier              {bootmgr}
 device                  unknown
 description             Windows Boot Manager
 locale                  en-US
 inherit                 {globalsettings}
 default                 {current}
 resumeobject            {d9491a3a-d7dc-11dd-8382-b9347c3c15cd}
 displayorder            {current}
 toolsdisplayorder       {memdiag}
 timeout                 5

 Windows Boot Loader
 identifier              {current}
 device                  unknown
 path                    \Windows\system32\winload.exe
 description             Windows 7
 locale                  en-US
 inherit                 {bootloadersettings}
 osdevice                unknown
 systemroot              \Windows
 resumeobject            {d9491a3a-d7dc-11dd-8382-b9347c3c15cd}
 nx                      OptIn`

I am curious why it shows device = unknown and osdevice = unknown for the {current} boot entry? Is this a problem? Can it be fixed manually?
