First, I am no expert in this area.
But, I have played Skyrim on at least three different laptops in the 12 plus years that I have played. The only save I load is the point where my character runs to either Hadvar or Ralof.
So, that I can avoid the same wagon ride to Helgen..................From there it is either I am a Stormcloak or Imperial or neither just a Rogue.
But no other game saves from another PC. I don't know if that is a good idea. Well, I don't know if that helps or not but good luck!
