I have a triple boot Ubuntu14.10/MacOSX/Windows 8 on my MacBook Pro.
However, Windows does not show up in grub, only MacOS and Ubuntu show up.
I tried a few things from other similar questions but nothing worked, like running update-grub
or Boot Repair
. Here are some program outputs which might be helpful:
fdisk
sudo fdisk -l

I guess /dev/sda3 might be windows !?
update-grub
sudo update-grub
