Based on:

...

In my option /dev/sda is the system disk and /dev/sdb the USB-drive.
I used 'Rufus' to write an image

Preparing

Change keyboard layout (optional), in my case it's German.

# localectl list-keymaps
# loadkeys <keymap> (e.g for German: `de-latin1` or `de`)

Connect to internet:

For LAN:
```
  # systemctl start dhcpcd.service
```
For WLAN:
```
  # wifi-menu
```

Partitioning

A drive should first be partitioned and afterwards the partitions should be formatted with a file system. Use fdisk to create MBR partitions.
```
# fdisk /dev/sda
```
First, create an empty MBR partition table. (WARNING: This will erase entire disk)
```
# (fdisk) o
```

I'm going to create 2 main partitions. (/dev/sda1 & /dev/sda2)

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sda1            2048    526335    524288   256M 83 Linux      /boot
/dev/sda2          526336 765986815 765460480   365G 83 Linux      Encrypted with LUKS, 3 LVM partitions:
    swap  vg0 -wi-ao----   8.00g                                   swap
    root  vg0 -wi-ao----  80.00g                                   /
    home vg0 -wi-ao---- XXX.XXg

Create Partitions:

# (fdisk) n
# (fdisk) p
# (fdisk) 1
# (fdisk) <Enter>
# (fdisk) +256M
# (fdisk) t
# (fdisk) <Enter>
# (fdisk) 83

# (fdisk) n
# (fdisk) p
# (fdisk) 2
# (fdisk) <Enter>
# (fdisk) <Enter>
# (fdisk) t
# (fdisk) <Enter>
# (fdisk) 83

# (fdisk) w

Format boot - Partition: (/dev/sda1)
```
# mkfs.ext2 /dev/sda1
```

Setup Encryption:

# cryptsetup -c aes-xts-plain64 -y --use-random luksFormat /dev/sda2
# cryptsetup luksOpen /dev/sda2 luks

Create LVM Partitions:

# pvcreate /dev/mapper/luks
# vgcreate vg0 /dev/mapper/luks
# lvcreate --size 8G vg0 --name swap
# lvcreate --size 80G vg0 --name root
# lvcreate -l +100%FREE vg0 --name home

Format LVM partitions:

# mkfs.ext4 /dev/mapper/vg0-root
# mkfs.ext4 /dev/mapper/vg0-home
# mkswap /dev/mapper/vg0-swap

Mount the new system:

# mount /dev/mapper/vg0-root /mnt
# mkdir /mnt/boot
# mount /dev/sda1 /mnt/boot
# swapon /dev/mapper/vg0-swap

Installing

Install the base system w/ important components:

# pacstrap -i /mnt base base-devel git vim lvm2 linux linux-firmware

Generate /etc/fstab. This file can be used to define how disk partitions, various other block devices, or remote filesystems should be mounted into the filesystem.
```
# genfstab -pU /mnt >> /mnt/etc/fstab
```

Configure New System

Enter the new system:
```
# arch-chroot /mnt /bin/bash
```
Set TimeZone:

See available timezones w/
```
  # ls /usr/share/zoneinfo/
```

Set timezone: (e.g. for Germany)

  # ln -s /usr/share/zoneinfo/Europe/Berlin /etc/localtime

Set Locale: (can be different if you use another layout)

# vim /etc/locale.gen (uncomment en_US.UTF-8 UTF-8)
# locale-gen
# echo LANG=en_US.UTF-8 > /etc/locale.conf
# export LANG=en_US.UTF-8

Set the hardware clock mode uniformly between your operating systems. Otherwise, they may overwrite the hardware clock and cause time shifts.
```
# hwclock --systohc --utc
```
Set hostname:
```
# echo <myhostname> >/etc/hostname
```

Add following to /etc/hosts:

127.0.1.1  myhostname.localdomain  myhostname

Create User:

# adduser <username>
# usermod -aG wheel <username>
# passwd <username>
# vim /etc/sudoers

Uncomment following:
```
  %wheel ALL=(ALL) ALL
```

Set root password:
```
# passwd root
```
Download/Configure mkinitcpio with modules needed for the initrd image:
```
# pacman –S mkinitcpio
# vim /etc/mkinitcpio.conf
```

Add ext4 to MODULES
Add encrypt and lvm2 to HOOKS before filesystems
```
  # mkinitcpio -p linux
```

GRUB

Setup grub:

# pacman -S grub
# grub-install --target=i386-pc --recheck /dev/sda

In /etc/default/grub edit the line GRUB_CMDLINE_LINUX to:

GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda2:luks:allow-discards"
[Tip] To automatically search for other operating systems on your computer, install os-prober (pacman -S os-prober) before running the next command.
```
  # grub-mkconfig -o /boot/grub/grub.cfg
```

Reboot

WARNING! Before you unmount & reboot, it’s highly recommended to install followings to have Internet-Connection:

For wifi-menu:

  # sudo pacman –S netctl dialog wpa_supplicant

For LAN:
```
  # sudo pacman –S dhcpcd
```

Exit new system and unmount all partitions:
```
# exit
# umount -R /mnt
# swapoff –a
```
Reboot into the new system: (Don't forget to remove the CD/USB.)
```
# reboot
```

Start network & check internet connection:

# systemctl enable dhcpcd.service
# systemctl start dhcpcd.service

# ping google.com

WARNING! There could be an error like below, after connecting w/ wifi-menu to your Network, e.g. Job for netctl@wlp0s19f2u2\networkname.service failed because the control process exited with error code. See “systemctl status “netctl@wlp0s19f2u2\networkname.service”” and “journal –xe” for details.

So what I did was:

  # systemctl stop dhcpcd.service
  # ip link set down wlp0s19f2u2

Then:

  # systemctl start netctl@wlp0s19f2u2\networkname.service

or
```
  # wifi-menu
```

GUI

Now you need GUI (I hope), for KDE Plasma:

Install xorg & sddm:

  # pacman -S xorg xorg-server xorg-xinit sddm xterm

Install graphics driver:
Use lscpi | grep VGA to detect your VGA Controller and install your one or install 'em all:
```
  # pacman –S xf86-video-intel xf86-video-amdgpu xf86-video-ati
```

Now install KDE & Enable Display Manager (sddm):

  # pacman –S plasma kde-applications
  # systemctl enable sddm

Now reboot:
```
# reboot
```
