Arch Linux Installation Guide

A beginner-friendly Arch Linux installation guide with:

• Manual installation steps
• UEFI support
• Dual boot support
• GRUB setup
• Post-install automation script

---

Requirements

Before starting:

• Backup important data
• Disable Secure Boot
• Create a bootable Arch Linux USB
• Boot in UEFI mode

Download Arch Linux ISO: https://archlinux.org/download/

---

Boot Into Arch ISO

After booting into the live environment:

ping archlinux.org

If using WiFi:

iwctl

Inside iwctl:

device list
station wlan0 scan
station wlan0 get-networks
station wlan0 connect WIFI_NAME
exit

---

Identify Disks

lsblk

Example NVMe drive:

/dev/nvme0n1

---

Partitioning (UEFI)

Open cfdisk:

cfdisk /dev/nvme0n1

Create:

Partition	Size	Type
EFI	512M	EFI System
Swap	Optional	Linux Swap
Root	Remaining	Linux filesystem

If dual booting with Windows:

• Reuse the existing EFI partition
• DO NOT format the EFI partition

---

Format Partitions

Example:

Partition	Usage
nvme0n1p1	EFI
nvme0n1p2	Swap
nvme0n1p3	Root

Format root:

mkfs.ext4 /dev/nvme0n1p3

Format EFI:

mkfs.fat -F32 /dev/nvme0n1p1

Create swap:

mkswap /dev/nvme0n1p2
swapon /dev/nvme0n1p2

---

Mount Partitions

mount /dev/nvme0n1p3 /mnt
mkdir /mnt/boot
mount /dev/nvme0n1p1 /mnt/boot

---

Install Base System

pacstrap -K /mnt base linux linux-firmware base-devel \
networkmanager sudo grub efibootmgr \
nano neovim git

Generate fstab:

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

Chroot into system:

arch-chroot /mnt

---

Download Installation Script

git clone https://github.com/USERNAME/REPOSITORY.git
cd REPOSITORY
chmod +x arch_install.sh
./arch_install.sh

---

Install GRUB

grub-install --target=x86_64-efi \
--efi-directory=/boot \
--bootloader-id=GRUB

Generate config:

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

---

Enable Windows Detection

Install os-prober:

pacman -S os-prober

Enable os-prober:

nano /etc/default/grub

Uncomment:

GRUB_DISABLE_OS_PROBER=false

Regenerate GRUB:

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

---

Finish Installation

Exit chroot:

exit

Unmount:

umount -R /mnt

Reboot:

reboot

Remove USB after reboot.

---

Post Install

Update system:

sudo pacman -Syu

Enable Bluetooth:

sudo systemctl enable bluetooth

Install audio packages:

sudo pacman -S pipewire pipewire-pulse wireplumber
