[Bug 1798746] Re: Grub install fail - ubuntu 18.10

[lyesseb]

Bug solved:
oot Ubuntu Live DVD/USB in testing mode and open terminal

    Run installation process without installing boot loader by:

    sudo ubiquity -b

    Press Continue testing after installation is over.

    Mount the newly installed file system into /mnt:

    sudo mount /dev/sda2 /mnt
    sudo mount /dev/sda1 /mnt/boot/efi
    for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done

    (Where sda6 is t root partition and sda1 is the EFI partition.)    
    
    Load the efivars module by:

    sudo modprobe efivars

    Reinstall grub-install for a 64-bit version:

    sudo apt-get install --reinstall grub-efi-amd64-signed
    sudo grub-install --no-nvram --root-directory=/mnt

    Change root to /mnt and update Grub:

    sudo chroot /mnt
    update-grub

    Move and rename the installed boot loader:

    cd /boot/efi/EFI
    cp -R ubuntu/* BOOT/
    cd BOOT
    cp grubx64.efi bootx64.efi

    Reboot the system
    update-grub
