Arch Linux dualboot install guide (October 2024)

Easiest and fastest way to install Arch Linux on your PC.

Installation

Disk partitioning

Once your Arch Linux ISO is ready to type commands do:

Open the CLI tool cfdisk to start partitioning the disk you want to install Arch:

$ cfdisk /dev/{YourDiskName}

And create partitions:

* EFI: 500M
* LINUX FILESYSTEM: the desired space for Arch

Apply changes and exit cfdisk.

Connect to internet wirelessly

$ iwctl
    > device wlan0 set-property Powered on
    > station wlan0 scan
    > station wlan0 get-networks
    > station wlan0 connect "wifi_name"

Archinstall script

$ archinstall

Fill everything as desired and in the disk section select manual and mount the / in the thick partition (linux filesystem mentioned above) and mount /boot in the EFI partition.

Install and wait for it to finish and reboot.

Post-install configurations

- LINUX HEADERS

When updating with sudo pacman -Syu if the initramfs gives errors when compiling, when updating pacman or when installing packages, you must install:

$ sudo pacman -S linux-headers # For Stable kernel
$ sudo pacman -S linux-zen-headers # For Zen kernel
$ sudo pacman -S linux-hardened-headers # For Hardened kernel

- WIFI

$ nmcli device wifi list    
$ nmcli device wifi connect "wifi-name" password "passwordHere"

Repair grub

This way you can see Windows installation on grub OS selector.

$ sudo pacman -S os-prober
$ sudo nano /etc/default/grub
    > Uncomment os-prober line
$ sudo grub-mkconfig -o /boot/grub/grub.cfg
