# Simple, modern and secure installation of Arch Linux with KDE Plasma.
**Load the preferred keyboard. In my case it's "de" for Germany.**
$ loadkeys de
$ loadkeys de
**List devices to make sure you partition the right device.**
$ lsblk
**Partition the device using gdisk (assuming /dev/sda).**
$ gdisk /dev/sda
**Create GPT and EFI-partion.**
$ o # _Creates new GPT-partition table._
$ y # _Accept._
$ n # _New partition._
$ +512M # _512 MB should be plenty for /boot._
$ ef00 # _Mark as EFI._
$ n # _New main partition, accept all the following using "y"._
**Print and check your partitions.**
$ p
**Write partitions to device.**
$ w
$ y # _Accept._
**Encrypt primary partition.**
$ cryptsetup -c aes-xts-plain -y -s 512 luksFormat /dev/sda2
$ YES

$ cryptsetup -c aes-xts-plain -y -s 512 luksFormat /dev/sda2
$ YES
**Open encrypted partition, map as "root" and create filesystem.**
$ cryptseup luksOpen /dev/sda2 root
$ mkfs.fat -F 32 -n UEFI /dev/sda1
**-F specifies the type of file allocation tables used (12, 16 or 32 bit).**
**-n sets the volume name (label) of the filesystem to "UEFI".**
**Create ext4 filesystem on primary partition.**
$ mkfs.ext4 /dev/mapper/root
**Create mountpoints and mount partitions.**
$ mount /dev/mapper/root /mnt
$ mkdir /mnt/boot
$ mount /dev/sda1 /mnt/boot
**Optionally update mirrorlist using reflector.**
**In this case use the latest 10 mirrors from Germany, that have been synchronized within the last 24 hours and sort the by download-rate and write them to the pacman mirrorlist.**
$ reflector --verbose --latest 10 --country Germany --age 24 --sort rate --save /etc/pacman.d/mirrorlist
**Install base system and basic packages (network, editor, sudo).**
**The package base-devel is not necessary but recommended.**
$ pacstrap /mnt base base-devel linux linux-firmware networkmanager nano sudo
**Generate fstab.**
$ genfstab -Lp /mnt > /mnt/etc/fstab
**-L = Use labels for source identifiers (shortcut for -t LABEL).**
**-p Exclude pseudofs mounts (default behavior).**
**Chroot into your installation.**
$ arch-chroot /mnt
**Set your hostname.**
$ echo mycomputer > /etc/hostname
**Generate locale.gen for your preferred language (and preferribly english).**
$ nano /etc/locale.gen
**Uncomment your language, e.g. de_DE.UTF-8 UTF-8 (and en_US.UTF-8).**
**Generate the locale.**
$ locale-gen
**Add necessary HOOKS and MODULES.**
$ nano /etc/mkinitcpio.conf
**MODULES=(ext4)**
**HOOKS=(base udev autodetect modconf block keyboard keymap encrypt filesystems fsck shutdown)**
**Create mkinitcpio.**
$ mkinitcpio -p linux
**Start NetworkManager for automatic network access on next boot.**
$ systemctl enable NetworkManager
**Set a root-password.**
$ passwd
**Install systemd-boot bootloader.**
$ bootctl install
**Create the bootloader config.**
$ nano /bootloader/entries/arch.conf
