I dual boot Windows 8.1 and Ubuntu 13.10 and have updated 13.10 multiple 
times with out that happening so what happened to you is not the norm.

Above you say "Windows was just gone".  What do you mean by that? If you 
mean you no longer saw the grub menu that allowed you to pick the OS you 
wanted to boot to.  The first thing I would try was to boot to Ubuntu 
and open a terminal and type    sudo update-grub  .  If the grub menu 
was somehow corrupted that should rebuild it and allow you to dual boot 
again.  If that doesn't work then someone with more knowledge than 
myself will need to help you.
