The stroy were i've installed Ubuntu 16.04 LTS then i installed Windows 10 on my laptop (dual boot). It was on UEFI mode installation.
So, when i restart my laptop, it boot into Windows 10. After that, i reinstall Grub from Ubuntu Live USB. But, it wasn't succeed
What i have done so far is :
Terminal :
ubuntu@ubuntu:~$ sudo mount /dev/sda2 /mnt
ubuntu@ubuntu:~$ sudo mount /dev/sda1 /mnt/boot/efi
ubuntu@ubuntu:~$ for i in /dev /dev/pts /proc /sys /run
> do sudo mount -B $i /mnt$i
> done
ubuntu@ubuntu:~$ sudo chroot /mnt
root@ubuntu:/# grub-install /dev/sda

EDIT
It is too long to reply @oldfred comment with this text. So i put it here.
Hi @oldfred .. i've been confusing about Operating System Booting settings. I set booting mode on UEFI (Secure Boot), after that i installed Ubuntu. During installation, it said i did something wrong (not recommended way) after created partition and it must be use Legacy BIOS to make dual-boot possible in the future. So, i went to change the Boot's Settings mode to Legacy BIOS. After that i installed Ubuntu with succeed. Then i installed Windows (still on Legacy BIOS mode). It was succeed as well. Then i went to recover GRUB to enable dual-boot. I followed this tutorial (https://www.linuxdeveloper.space/install-windows-after-linux/#repair-grub-efi). I reboot my laptop .. just end up with Windows appeared after booting.
Any idea why i can't reinstall grub ?
