Whether you’re a seasoned Linux user or a newcomer, this guide will walk you through the process in a simple and understandable way. Arch Linux allows you to build your Linux system from the ground up, ensuring that you have complete control over every aspect. So, let’s dive into the world of Arch Linux and learn how to easily install it.

How to Easily Install Arch Linux?

Arch Linux installation is a two-step process. First, you need to prepare a bootable USB drive with the Arch Linux ISO file, and then you can proceed to install the system on your computer. Let’s break it down step by step.

Step 1: Create a Bootable USB Drive

Download the Arch Linux ISO: Visit the official Arch Linux website and download the ISO image for the latest version.

Prepare a USB Drive: Use a tool like Rufus (on Windows) or dd (on Linux) to write the ISO to a USB drive. Make sure the USB drive is empty, as the process will erase all data on it.

Boot from the USB Drive: Insert the bootable USB drive into your computer and restart it. You may need to change the boot order in the BIOS/UEFI settings to boot from the USB drive.

Access the Arch Linux Installer: Once booted from the USB drive, you’ll be greeted with the Arch Linux command-line installer.

Step 2: Install Arch Linux

Set the Keyboard Layout: Use the loadkeys command to set your keyboard layout. For example, if you have a US keyboard, use loadkeys us.

Check Internet Connectivity: Ensure you have an internet connection; you can use the ping command to test it.

Partition Your Disk: Use a tool like cfdisk or fdisk to partition your hard drive. Create partitions for root, home, and swap if desired.

Format and Mount Partitions: Format the partitions with the mkfs command and mount them to /mnt. For example, mkfs.ext4 /dev/sda1 and mount /dev/sda1 /mnt.

Install the Base System: Use pacstrap to install the base system. For instance, pacstrap /mnt base base-devel.

Generate an fstab File: Generate an fstab file to define how partitions should be mounted at boot using genfstab -U /mnt >> /mnt/etc/fstab.

Chroot into the New System: Use arch-chroot /mnt to enter the new installation environment.

Set the Timezone: Use ln -sf /usr/share/zoneinfo/Region/City /etc/localtime to set your timezone.

Configure Localization: Edit /etc/locale.gen to uncomment your desired locale(s) and run locale-gen. Then, create /etc/locale.conf and set your locale, e.g., LANG=en_US.UTF-8.

Set Hostname: Create /etc/hostname and enter your chosen hostname.

Set Root Password: Set the root password with passwd.

Install and Configure a Boot Loader: Install a boot loader like GRUB or systemd-boot and configure it.

Create a User: Create a non-root user with useradd -m -G wheel username and set their password with passwd username.

Configure sudo: Edit /etc/sudoers to allow your user to use sudo.

Install Additional Packages: Install any additional packages you need, such as a desktop environment or software.

Enable Network Services: Enable network services like NetworkManager or systemd-networkd.

Exit Chroot Environment: Exit the chroot environment with exit.

Unmount Partitions: Unmount the partitions with umount -R /mnt.

Reboot: Finally, reboot your system with reboot, and you should be greeted with your newly installed Arch Linux system.
