The grub is the boot loader must always install Linux and Windows first before any linux distribution if we have both so, because Windows overwrites the boot sector by removing grub.

If for some reason we can recover Windows reinstall grub downloading the disk Supergrub
Once we have the partition boot Ubuntu from your hard drive console write sudo grub-install / dev / sda (that would reinstate the grub on sata disk).

An example of grub menu.lst file stay in / boot / grub / where Windows is located on the primary partition and Linux in logical partition of a single Sata drive would be as follows:
