Multiple Boot Managers and/or active partitions error
Hello,
I get an error, about once every 4/5 months when the PC is interrupted via a power surge or incorrectly turned off during a restart that results in me having to fix, reset and rebuild the boot manager. It's a quick and usually painless process. I'm on Windows 10, 64bit, Home Edition and haven't installed any OS updates in a few weeks.
However today I made an error when bootrec /fixboot was giving me an access denied response, and made things considerably worse, and continued to double down on these errors until I realised the extent of my mistake.
C Drive, is where the OS is (well used to be at this rate) installed. It only had two partitions to the extent of my memory and one of them was for Windows. D Drive is just the main hard drive, nothing windows related on there.
On my BIOS, it used to list both of my hard drives on there. Now it only lists my C: Drive and the D: Drive is just called Hard Disk Windows Boot Manager.
I believe the command that sent everything down hill was bcdboot D:\Windows, which I now realise was where it all began and made things worse as I attempted to correct it.
Following info is all from the CMD prompt in windows recovery.
C Drive now has Windows.old on it, instead of Windows.
D Drive now has Windows, Windows.old and Windows10Upgrade on it.
Needless to say that should probably be the other way around, also not sure where the upgrade folder came from.
DiskPart gives the following:
Disk 0 | Online | 2794 GB | Free 0B | Dyn (Blank) | Gpt ( * ) - D Drive

I can't think of anything else relevant that I've seen in the past two hours, but this all happened because bootrec /fixboot said Access Denied, so I tried alternative solutions on the internet and a typo ruined me. I've tried two system restores to yesterday and last week to no avail, the in-built automatic repair is stuck in a loop of no fixing and starting again, I am currently creating a recovery disk on my laptop to put on a USB drive but I'm not hopeful of that fixing everything.
I tried setting C: as active, but it said it couldn't set that drive as active because it wasn't MBR and D: gave the same error.
I tried to copy the boot mgr over to C: but it said there was an error preventing me from copying it.
I'm very hesitant to try anything else on the risk it'll make it worse or force me to do a full wipe. My external HD died suddenly last weekend, so I was going to replace it this month, there's timing for you.
Any advice would be greatly appreciated, apologies if I haven't explained anything clearly. Basically windows is now on the wrong hard drive, can't copy it to the proper one, don't have access to fix the boot, automatic repair does nothing and there's a lot of volumes and partitions that I'm paranoid to delete or format.
Muchos Gracias.
