Recover Grub

I am using a system which is dual boot, can be switched to windows 10 or Ubuntu 16 via grub.

Windows 10 update corrupted the grub and i see this error.

error: no such partition.
Entering rescue mode...
grub rescue>

How to resolve this.

Make a bootable USB for ubuntu 16 and boot your system in Live mode through this usb
