Arch linux installation is not that hard if you do it simple as if;

• you don't need dual boot and just want to install it as first OS on your drive.

• your computer is not too old and it supports GPT, UEFI, etc.

• you don't need LVM, system encryption or RAID.

• you don't mind to read the wiki pages.

If so, it is done in 10 minutes (without downloading and installation time). In this tutorial, The Arch Linux is installed as

• no dual boot, single OS

• using GPT and UEFI using systemd-boot

• keep it simple and stupid

Preparing installation media

the best and simple command example

# dd if=/path/to/archlinux-version-x86_64.iso of=/dev/sdb

Boot up from the installation media

Getting the installation media booted up, choosing UEFI in boot menu if needed. How to get the installation booted up?

Connect to internet

To connect to internet (WiFi) using iwd,

# iwctl

Partition

Partitioning the disk using gdisk (gdisk is personally recommended in this tutorial) is done as the following table

1. /dev/sda1
   500MB-1GB is recommended, it is to be mounted at /boot
   choose partition type ef00
   format it for FAT32 filesystem
   # mkfs.fat -F32 /dev/sda1

2. /dev/sda2
   30GB is recommended, it is to be mount at /
   choose partition type 8300
   format it for ext4 filesystem
   # mkfs.ext4 /dev/sda2

3. /dev/sda3
   depends on RAM, at least 4GB is recommended, it is to be swap
   choose partition type 8200
   no need to format it but do
   # mkswap /dev/sda3

4. /dev/sda4
   it is to be mounted at /home
   choose partition type 8300
   format it for ext4 filesystem
   # mkfs.ext4 /dev/sda4

gdisk and formatting commands

# gdisk /dev/sda

? for help and follow on-screen instruction

-----

# mkfs.fat -F32 /dev/sda1

# mkfs.ext4 /dev/sda2

# mkswap /dev/sda3

# mkfs.ext4 /dev/sda4

... to add more information for partitioning by using gdisk.

Mounting

Mounting, creating mount point directories and activating swap

# mount /dev/sda2 /mnt

# mkdir /mnt/boot

# mkdir /mnt/home

# mount /dev/sda1 /mnt/boot

# mount /dev/sda4/mnt/home

# swapon /dev/sda3

Installation

Installing base system and other important packages such as linux, linux-firmware and base-devel.

# pacstrap /mnt base linux linux-firmware base-devel

Configuration

/etc/fstab

# genfstab -U /mnt >> /mnt/etc/fstab

chroot

# arch-chroot /mnt

Time Zone

# ln -sf /usr/share/zoneinfo/Asia/Yangon /etc/localtime

# hwclock --systohc

Localization

# nano /etc/locale.gen

---Uncomment en_US.UTF-8 UTF-8

---# pacman -S nano ---if nano command not found

-----

# locale-gen

-----

myhostname

-----

# nano /etc/hosts

127.0.0.1 localhost

Root password and new user

Setting root password, creating new user, password and giving administrative permission

# passwd

-----

# useradd -m -G wheel -s /bin/bash myusername

# passwd myusername

-----

# visudo EDITOR=nano

---uncomment the line

%wheel ALL=(ALL) ALL

Bootloader

In this tutorial, systemd-boot is used as bootloader.

# bootctl install

-----

# nano /boot/loader/entries/arch.conf

title Arch Linux

linux /vmlinuz-linux

initrd /initramfs-linux.img

options root=/dev/sda2 rw

Reboot

Exit from chroot, unmount and reboot.

# exit

# umount -R /mnt

# reboot

Post Installation

The base installation has been successfully installed. It is time to move on.
