Windows 7: Which MBR fix is correct?

To clarify--

I'm inclined to believe that I fixed whatever problem lurked within the MBR. The problem that she was experiencing was a 'random' boot load failure. The boot stop seemed to be associated with a more 'energetic' boot typically after a raft of updates. I've now updated her machine 3 times post my MBR attempted fix and all with required boots and all attempts have booted just fine to this point. That is not to infer the problem is no more. The only sure fire way of confirming that is more time and more boots.

Yesterday, at the time of repairing her MBR, since I did not run the switch /scanos and she clearly has an active (C) partition (attachment), I remained confused why the switch /RebuildBcd unsolicitously returned (in addition to a successful result) "Total identified Windows installation=0"

This is reported by others and I admit it is a confusing message. My guess was that the BCD had an entry for a Windows "Winload.exe" but that this was wrong and you had to delete the BCD before rebuilding. This is described at the end of the MS guidance I referred you to. However, the PC is booting so I am also a little confused would hope
bootrec /scanos
would identify an OS.

Aside:
I don't know specifically about Lenova but the SYSTEM_DRV looks a little odd to me in that it has a lot of free space.

The Bootrec /scanos reports essentially the same information as did bootrec /RebuildBcd: Total identified Windows installation=0, Operation completed successfully.

It's possible that the clue to this mess is the automatic scan screen that occurs just before the repair screen listing one's action options.

The result was of that automatic scan:

Operating system Partition size Location
Windows 106603 E<----patently wrong

Somehow the diagnostic is seeing the active partition as E whereas it's clearly C (re: my disk management post earlier in the thread).

The E drive is my wife's 2 of 2 physical data only drive (a third data only, D, is attached externally using USB)

I have no clue as to how the repair disk finds the active disk to be on one drive and the loaded OS vis a vie disk management finds the active disk to be totally different.

FWIW, the active drive C is an SSD.
