I used solution from http://superuser.com/questions/376470/how-to-reinstall-grub2-efi in combination with installation of efibootmgr mentioned above after chrooting and before grub commands and it works.

Another solution could be:
mkdir /mnt/efi
mount /dev/sda1 /mnt/efi
mkdir /mnt/efi/EFI/boot
cp /mnt/efi/EFI/ubuntu/grubx64.efi /mnt/efi/EFI/boot/bootx64.efi

but then SecureBoot doesn't pass
