No, you haven't understood what I have said, or I haven't made myself clear enough.
Clean install Win 10 from a bootable Win 10 medium.
Using an iso you can mount it having logged in, then you can upgrade, repair install...
As you should know, the system restarts 2 or 3 times during installation: a mounted disk content it held in RAM so... no.
As my points are deemed irrelevant given your puzzling comments about migrating data, I'll leave you with it. Good uck!
