I recently purchased an SSD to upgrade from my HDD, I want to move windows 10 over, but have no idea how. To add to the issues, I do not have a Windows 10 product key, it's a Windows 8 product key that have been upgraded to 8.1 then 10 via the updates Microsoft we're releasing back then. I also want to leave my programs and files on my HDD so that it's only the OS being moved for now.
For those marking this as a duplicate, I can't clone the HDD as it is 2TB and nearly full, the SSD is only 128GB, hence only wanting the OS on there.
