The Installation Process

The installation process of Arch Linux is divided into several steps. Below, we will detail each step thoroughly.

Step 1: Boot from USB

Insert your bootable USB drive into your computer and boot from it. You may need to change the boot order in your BIOS settings.

Step 2: Set Up Your Internet Connection

Once booted into the Arch live environment, connect to the internet. For wired connections, you can usually connect automatically. For wireless, use the command:

iwctl

Follow the prompts to connect.

Step 3: Update the System Clock

Ensure your system clock is accurate before proceeding:

timedatectl set-ntp true

Step 4: Partition the Disk

Use the fdisk utility to partition your disk. The most common partitions are:

For example:

fdisk /dev/sda

Step 5: Format the Partitions

Format your partitions with the appropriate filesystem. For example:

mkfs.ext4 /dev/sda1

Step 6: Mount the Partitions

Mount your root partition using:

mount /dev/sda1 /mnt

Step 7: Install the Base Packages

Use the following command to install the base system:

pacstrap /mnt base linux linux-firmware

Step 8: Generate fstab

Generate your filesystem table with:

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

Step 9: Chroot into the New System

Change root into your new installation:

arch-chroot /mnt

Step 10: Set the Time Zone

Set your time zone with:

ln -sf /usr/share/zoneinfo/Region/City /etc/localtime

Then sync the hardware clock:

hwclock --systohc

Step 11: Localization

Edit the /etc/locale.gen file to uncomment your desired locales, then generate them:

locale-gen

Set your locale:

echo "LANG=en_US.UTF-8" > /etc/locale.conf

Step 12: Network Configuration

Set your hostname:

echo "myhostname" > /etc/hostname

Configure your hosts file:

echo "127.0.0.1 localhost" >> /etc/hosts

And also for your hostname:

echo "127.0.0.1 myhostname.localdomain myhostname" >> /etc/hosts

Step 13: Install a Bootloader

Install GRUB as your bootloader:

pacman -S grub

Then install it to your disk:

grub-install --target=i386-pc /dev/sda

Generate the configuration file:

grub-mkconfig -o /boot/grub/grub.cfg

Step 14: Exit and Reboot

Exit the chroot environment and unmount the partitions:

exit
umount -R /mnt

Finally, reboot your system:

reboot
