Step by step installation of Arch Linux on my Dell Inspiron with the following hardware:
- 11th Gen Intel Core i5-1135G7 @ 2.40GHz x8 (Tiger Lake)
- 15.4GB DDR4 Memory
- Mesa Intel Xe Graphics (TGL GT2)
- 1TB SSD (replaced the 250GB nvme drive)
My complete lspci output is:

#1 Download Arch Linux and write it to a USB drive – https://www.archlinux.org
#2 Boot Arch Live – too many variables to tell you how your system launches the boot menu – check DuckDuckGo or StartPage.com to more on your computer. On my Dell Inspiron I have to press F12 at boot to get a menu of devices. Your mileage may vary.
#3 Connect to the internet – If you’re on a wired connect, this is usually automatic (assuming your hardware is supported). For wireless, I used the iwctl utility, which is simple and fairly intuitive. As of mid-2020, it seems like the old wifi-menu utility was no longer included.
#4 Create your partitions and setup your encryption – For this installation, I chose to have two paritions on my 1TB SSD. One for the boot files (/dev/sda1) and one for the encrypted system and user files (/dev/sda2). I used cfdisk, but you can do the same with cgdisk or fdisk. /dev/sda1 gets 512M of space, while /dev/sda2 gets all the rest.
Now let’s setup the encryption (note that anything preceded with # is a comment of mine and not something to type):
# Encrypt the partition. You will be prompted to accept the changes by typing 'YES', and to enter a unique passphrase. DO NOT FORGET THIS PASSPHRASE. cryptsetup -y -v --use-random luksFormat /dev/sda2 # Now let's decrypt the partition os that we can format it and install the operating system and applications. cryptsetup luksOpen /dev/sda2 crypt # We need to create our logical volume management infrastructure, so let's create some root and swap volumes. pvcreate /dev/mapper/crypt vgcreate vg0 /dev/mapper/crypt lvcreate --size 8G vg0 --name swap lvcreate -l 100%FREE vg0 -n root # Format your root, boot, and swap partitions mkfs.vfat -F32 /dev/sda1 mkfs.ext4 /dev/mapper/vg0-root mkswap /dev/mapper/vg0-swap
#5 Mount the partitions
# Mount the root partition first mount /dev/mapper/vg0-root /mnt # Now create a directory for the boot partition and mount it mkdir /mnt/boot mount /dev/sda1 /mnt/boot
#6 Install the base system and enter it for next steps
# We need to have at least the following packages in order to have usable basic installation, though one or two is my personal preference # If you are using an Intel processor like I am, then use the below as is. If AMD, then substitute "intel-ucode" with "amd-ucode" # Also, if you have a TIger Lake based system, then you will likely need to install the "sof-firmware" package as listed below in order to have audio working, otherwise omit it. pacstrap /mnt base base-devel neovim efobootmgr linux linux-firmware lvm2 mkinitcpio networkmanager intel-ucode git efitools wget python sof-firmware dialog wpa_supplicant # /etc/fstab is a file that tells the system which disks/partitions to mount and where to do so, so we'll generate one and save it on the new system # Note that at least once in the past I saw an error that the path doesn't exist, so if that happens then just to a quick mkdir /mnt/etc/ prior to running the below commands again genfstab -U /mnt >> /mnt/etc/fstab # Now let's enter the new system. All commands after this one (well, almost) will be done entirely within your new Arch Linux installation arch-chroot /mnt
#7 Configure the rest of the system
# Setup your timezone for the clock. Available options are in the /usr/share/zoneinfo/<country/region> folder. Since I am in the upper-midwest of the US, here is what I did: ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime hwclock --systohc # We need to set the system locale so that all times, dates, currency, etc. are represented in a manner that is appropriate for your location. # In this case, I am using en_US.UTF-8 which basically means US English, encoded in UTF-8, so I open the file below and go to the line that says '#en_US.UTF-8' and remove the '#'. Close the file. nvim /etc/locale.gen # Generate the locale so the system can use it locale-gen # Set my locale information echo LANG=en_US.UTF-8 > /etc/locale.conf # Choose and set a hostname. Back when I was in IT, we used themes for all the hostnames on a network. For example, we might have a couple of racks of systems that are all named after characters from a popular movie or cartoon. echo hostname_I_chose > /etc/hostname
#8 Setup the root password and the user account
# Set the root password. It will prompt you to enter it twice to make sure you didn't typo passwd # Create a user and assign it to the right groups. Replace myusername with whatever you want to use. Then assign it a unique password. DO NOT MAKE THE USER AND ROOT PASSWORDS THE SAME. useradd -m -G wheel,audio,video myusername passwd myusername
#9 Setup the system to be able to boot without the USB drive
# Edit the mkinitcpio.conf file to make sure that the boot image built can decrypt the partition # Make sure that the HOOKS section looks like this # HOOKS=(base udev autodetect modconf block keyboard encrypt filesystems fsck) # Now make sure that the MODULES section contains ext4 and i915 nvim /etc/mkinitcpio.conf # Generate the boot image mkinitcpio -p linux # Install systemd-boot bootctl --esp-path=/boot install # Create the loader.conf file echo 'default arch' >> /etc/loader/loader.conf echo 'timeout 5' >> /etc/loader/loader.conf # Create arch.conf with nvim /boot/loader/entries/arch.conf # First, you need to get the UUID of the encrypted device (/dev/sda2). Use the 'blkid' command and write down the hexadecimal value for UUID. In my case, it was a71d3236-b817-4314-9601-17318aefea65 # Add the following entries (substituting your own UUID) title Arch Linux linux /vmlinuz-linux initrd /intel-ucode.img # Substitute amd-ucode.img if you're on AMD initrd /initramfs-linux.img options cryptdevice=UUID=a71d3236-b817-4314-9601-17318aefea65:crypt root=/dev/mapper/vg0-root rw # Verify the boot options bootctl status
#10 Install any remaining packages and reboot into your new Arch Linux installation
This part is really up to you. Most people are going to opt for installing some kind of Desktop Environment (Gnome, Mate, KDE, etc.) or Window Manager (i3wm, bspwm, etc.)
A Desktop Environment gives a holistic experience with a low learning curve. If you’ve ever tried Ubuntu, then you’ve seen a customized version of Gnome.
A Window Manager is just that – it manages the open windows, their placement, shortcuts, etc., but allows you to setup all the other niceties such as a dock or panel, applets, or menus.
# For this example, we're going to install Gnome, a web browser (though it includes one by default, I prefer Firefox), zsh (my preferred shell) # First, update the packages information so the system knows what the latest/greatest available is pacman -Sy # Now install the Desktop Environment and applications pacman -S gnome firefox xorg-xinit zsh
#11 Exit the system and reboot into your newly installed operating system and desktop environment
# Exit the system and unmount the partitions so that we can cleanly reboot exit umount -R /mnt # Reboot the system (Don't forget to remove the USB drive when the system reboots, not before and not too late so that it doesn't boot back in to USB again. reboot
