I'm sorry; I just can't help asking why so many of you youngsters play
the age card? Do you imagine that it encourages help and support?

Now to your question. Of course you won't need to re-install Ubuntu
and/or Win10. You've already established that they both start correctly
so obviously you have changed something related to GRUB, perhaps
unwittingly via an update, or the installation of some software. I would
firstly try the following:

<sudo update-grub>

and see what happens. By the way, the <> around the command are just
de-limiters - not to be typed. If that doesn't fix your screen problem
you might next try to re-install GRUB. A quick Google search for
"re-install GRUB" produces a wealth of information.
