I have installed ubuntu 14.04 on my machine and before installing ubuntu, I had a windows 10 on my machine. Before installing ubuntu, windows was hibernated and now I can't find it in my GRUB menu nor I can mount it with nautilus.
My machine had a Free DOS installation on it and now I technically should have 3 operating systems, but windows is not showing up.
I have tried using the boot-repair tool, but nothing changed.
