Replacing HDD, just learned it has bootmgr on it. How to move elsewhere without clean installing?

So I just popped in my 2nd Corsair MP500 NVME/M.2 SSD, both of which I absolutely love. I had thought I would be somewhat painlessly be able to get a pair, each 480GB, one with windows on it and all my games and such, and another for long term data storage, and be rid of all my clunky old HDD's that could fail whenever. SSD's obviously fail too but obviously don't have the moving parts HDD's do, and I'm also always looking to clean up inside the case.

Anyway, it went fine until I started getting "Bootmgr is missing" errors on startup and having no option but to restart. I kept restarting and unplugging different drives before realizing, given that I did not have M.2 #2 at the time I installed win10, the boot manager must be on one of the HDD's. It is the only HDD I have not yet removed but I want to, so my question is:

Can I do this, thus requiring I move the boot manager somewhere, without reinstalling? Or even reinstalling without losing any data, i.e. saved games installed on M.2 #1, etc. If I've no other practical option, fine, I'd just rather avoid starting fresh again, just did it at the beginning of the year when I rebuilt my system.

Thank you!!
 
Solution
Windows by default installs the boot manager on a different drive to Windows .Download easyBCD, a utility that will let you move the boot manager whereever you like.

Brief followup: All set, 100% HDD free. Used EasyBCD, specifically and exclusively the "change boot drive" option under the "BCD Backup/repair" section of the program.

From there, it simply asks what drive you desire the new COPY to be on (it duplicates, rather than moves, the bootloader, which is nice for insurance). You select it from a dropdown menu, click OK, and you're good, at least to solve my specific problem of the bootmgr not being found because it was on a different drive than windows, a drive I was also phasing out.

Take care.
