appropriate commands 5 Mount Partitions Mount the partitions to their respective mount points using mount For example mount devsda2 mnt 6 Generate fstab Use genfstab U mnt mntetcfstab to generate the etcfstab file which tells the system how to mount partitions on boot 7 Install the Base System Execute pacstrap mnt base basedevel This command downloads and installs the essential Arch Linux packages 8 Generate the initramfs Generate the initial RAM filesystem using archchroot mnt gentoochroot mnt gentoochroot mnt make jnproc replace gentoochroot with archchroot if you havent installed gentoo base 9 Configure the System archchroot mnt enters the newly installed system Set the hostname hostnamectl sethostname yourhostname set the locale localegen set the timezone timedatectl settimezone yourtimezone and create a root password passwd 10 Install a bootloader Install GRUB GRand Unified Bootloader using pacman S grub and then install it to your boot drive using grubinstall devsda replace
