4--Mount Partitions:

    mount -t btrfs -o ssd,noatime,discard,space_cache,compress=lzo,subvol=Debian /dev/sde2 /mnt
    mount -t btrfs -o ssd,noatime,discard,space_cache,compress=lzo,subvol=DebianHome /dev/sdc /mnt/home
    mount -t btrfs -o autodefrag,noatime,space_cache,compress-force=lzo /dev/sda /mnt/My_Files
    mount -t btrfs -o ssd,noatime,discard,space_cache,compress=lzo /dev/sdd2 /mnt/Games

    apt install firmware-linux-free
    apt install firmware-linux
    apt install firmware-linux-nonfree

15--Configure the Booting Process

    nano /boot/loader/entries/debian.conf
        title   Debian
            linux   /Debian/vmlinuz
            initrd  /initrd.img
        options root=PARTUUID=.... rootflags=subvol=Debian rw

    chmod +x /etc/kernel/postinst.d/zz-update-efistub
    ls -la /boot/Debian/

16--Exit chroot, Unmount partitions and reboot
