There isn't any practical difference in "manual upgrade" as you call it, and a re-install where you keep everything.
And this is splitting hairs over an unrelated issue. Inherently unhelpful.
The only mildly helpful comment is "it means your PC drivers aren't ready." - Can you elaborate further on that? Can you give an example on how to verify the "readiness" of the drivers?
If not, then it is better to allow someone who actually _can_ further this discussion to get a chance at replying.
Thanks.
