Yesterday, I installed Ubuntu 18 on my laptop. Before installing, I had a dual-boot with Windows 10 and Ubuntu 16, yet now I don't have the option for Windows - instead, I have Ubuntu 18 (+settings), Ubuntu 16 (+settings) and "System Setup".
I can still view the Windows files through Nautilus. I tried searching through countless questions here, yet none worked.
Is there a way to make Windows appear in GRUB again?
EDIT: After referring to the comments below, I have somehow managed to add an option for "Windows 7" (even though I have W10) which does not work.
