# The problem can be solved as follows:

# Boot Ubuntu Live DVD/USB in testing mode and open terminal

# Run installation process without installing bootloader by:

# sudo ubiquity -b
# Press Continue testing after installation is over.

# Mount newly installed file system on /mnt:
sudo mount /dev/sda2 /mnt
sudo mkdir /mnt/boot/efi
sudo mount /dev/sda1 /mnt/boot/efi
for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done
# (where sda2 is the root partition and sda1 is the EFI system partition)

# Load efivars by:
sudo modprobe efivars

# Reinstall grub-install for a 64-bit version
sudo apt-get install --reinstall grub-efi-amd64
sudo grub-install --no-nvram --root-directory=/mnt

# Change root to /mnt and update grub
sudo chroot /mnt
sudo update-grub

# Move and rename the installed bootloader
cd /boot/efi/EFI
sudo cp -R ubuntu/* BOOT/
cd BOOT
sudo cp grubx64.efi bootx64.efi

# Reboot the system.
echo "now you can reboot to test if boot problem is fixed now"
