Windows Boot Manager is on wrong hard drive.

[PopsicleHustler]

I need some help here because I'm totally confused right now. My Windows 10 is installed on 240SSD that was bough for this purpose. Yet Windows boot manager is somehow located on secondary HDD that I want to throw out because its old and dying.

 

There are no folders on that HDD that are visible in Windows. But in Bios it says otherwise.  So when I remove HDD, Windows boot manager disappears and I cannot load into windows even though Bios sees SSD that has Win 10 on it. How can I move that partition onto my main C drive so I can get rid on old HDD without having to re-install windows.

 

I'm literally in a middle of an open hearth surgery here with drive hanging outside PC case with 2 wires. So any help is appreciated.

Yep, Windows portions off a 100MB partition in your drive for the MBR and what I had to do was create a 100MB partition on my new drive and use command prompt off the Windows USB to transfer the files using some commands (bcdboot if I remember correctly). After that, make sure you set the partition with your new windows install as the active partition and you should be good!

Thanks. That helped.

That's why I always recommend to disconnect all drives from a system except the one you want to install to before starting a windows install, it's happened to me several times before that it chooses to put the boot stuff on another random drive if it's got any to choose from.
