    Executing grub-install dummy failed. Dual boot Kali with Win8.1

    Hi everyone,
    I try to dual boot Windows 8.1 and Kali Linux. Both 64bit
    My system:
    HP 15 Notebook
    Intel Core i3
    RAM: 4Gb
    EFI: 260Mb
    Win8.1: 400Gb
    Kali Linux: 41Gb, swap: 4Gb

    Installation process is going well, until we get to GRUB installation, I get following error:
    "Unable to install GRUB in dummy
    Executing 'grub-install dummy' failed.
    This is a fatal error."
    After installation I can't boot into Kali. It only boots straight to Windows. In BIOS only one option.
    I tried to fix it in Kali Live by these codes:
    root@kali:~# fdisk -l
    Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 4096 bytes
    I/O size (minimum/optimal): 4096 bytes / 4096 bytes
    Disklabel type: gpt
    Disk identifier: 643DF040-936C-4458-BCBA-5CB01F8BB356
    Device         Start       End   Sectors   Size Type

    Partition table entries are not in disk order.
    sudo mount /dev/sda6 /mnt 
    mount —bind /dev /mnt/dev 
    mount —bind /proc /mnt/proc 
    mount —bind /sys /mnt/sys 
    mount /dev/sda2 /mnt/boot/efi 
    mount -o remount,rw /dev/sda2 /mnt/boot/efi 
    mkdir /mnt/hostrun 
    mount —bind /run /mnt/hostrun 
    chroot /mnt 
    mkdir /run/lvm 
    mount —bind /hostrun/lvm /run/lvm 
    grub-install /dev/sda
    HereI get:
    Installing for x86_64-efi platform.
    grub-install: error: cannot open `/boot/efi/EFI/kali/grubx64.efi': Input/output error.

    Can someone help?
