Boot partition on wrong disk

Hardware Build a PC
1

I have a build with
. 2tb m.2 ssd (main drive)
. 2tb hd (want to get rid of, previous main drive)
. 4tb hd

I have a kinguin win 10 home oem license.

After an apparently successful install, I wish to remove the 2tb hd from my system, but when I do, my computer is unable to boot. It can’t find a bootable partition.

When I installed windows, I installed a clean install (oem) on the 2tb ssd. Somehow, it decided to put the boot manager on 2tb hd.

I have a couple quesitons:

  1. Is it possible to move the boot partition to my ssd? If so, how?

  2. If it is not possible to move the partition, and I am forced to re-install without the 2tb hd being connected, even though I kept a copy of the confirmation number for the activation, will I have issues activing windows? Does the installation ID generated by the system remain the same for the same product key and only a 1-of-3 change to the disks?

in this instance you would have 2 simple choices from the start
remove the old hdd and do your install fresh, or clone the old drive to the new one
cloning a drive copies everything including the boot partition.
that being said using partitioning software you can move partitions to different drives but you need to know how to flag them.

I haven’t used windows for over 10 years but i believe you may be able to do this with the disk manager
