I apologize up front. I am sure this has been asked a million times. I have an acer aspire, It has a 500GB ard drive so I made a 200MB partition. I installed kde neon on the new partition. But now when I boot it up it goes straight to neon. I don't have the option to choose windows or kde. HELP!!!!!!

I verified that the windows partition is still in tact. Is it a grub issue? Win 10 issue?
