* =================== Suggested repair The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of sda6 into the MBR of sda. Additional repair would be performed: unhide-bootmenu-10s fix-windows-boot
=================== Final advice in case of suggested repair
The boot files of [The OS now in use - Ubuntu 16.04.1 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)

I dont know what to do now. Help please.
sudo update-grub
? Turn off Windows 10 fast start up if on. You would have to install Windows boot loader to MBR, boot Windows and turn off fast start, then reinstall grub. Grub only boots working Windows which also means not hibernated.
