Installed Windows on a new SSD — didn’t get the Boot Manager with it? – Windows 10 Support – BleepingComputer

I’ll start off by saying that I did a dumb thing and that’s why I’m here.


I purchased a new WD_Black NVMe SSD for my PC. I was previously using two Kingston SSDs with one being for storage/backup and the other being for the OS, software, games, etc.


In my mind I didn’t think I would need to uninstall Windows from the previous primary drive when installing to the new WD drive. I was wrong apparently. I’ve installed Windows 10 Pro Version 21H2 (OS Build 19044.1889) and it works fine except that it didn’t create a boot manager partition when I did. So I did a lot of Googling a found a guide on how to create one but unfortunately my PC doesn’t recognize it despite it being listed in the Disk Manager


So aside from having now wiped the old primary drive’s free space, both the boot manager and the recovery partitions are still on the previous drive. I can’t seem to figure out a way to move them or clone them to the new drive. 


If I try to boot directly off the new WD drive from the BIOS, it attempts to install Windows and then gives me an error saying there’s an operating system already present and to go to Windows (I’m assuming it’s picked up the boot manager that still exists on the other drive?).


I’ve bumbled around with both Macrium Reflect and AOMEI Partition Assistant but haven’t had any luck cloning the recovery and boot manager partitions to the new drive, I’m guessing because Windows is now installed on the new WD drive so it can’t be dismounted to do whatever these programs need to do.


I’ve Googled as much as I can at this point so, here I am. Does anyone have any advice as to how I could fix this? If there’s a way to get the recovery partition that would save me some time as I haven’t gotten too far with software installations. 


Here’s what the partitions currently look like. As you can see I was able to create an EFI and Recovery partition on the new drive but I don’t think they’re actually doing anything other than taking up space.
