Hi all, welcome to MusaBase!. In this article, I'll guide you through installing Arch Linux with the archinstall script and make your Arch Linux installation easier. Without further ado, let's get started.

Step 1: Partitioning & Formatting Storage Disk

1.1: Boot into the Arch Linux Live Installation Environment

Reboot your PC.
Press F9, F10, F11, F12, Esc, or Del, (depending on your motherboard) to enter BIOS/UEFI settings.
Locate and disable Secure Boot.
Save changes and exit.
When prompted, press the key to select a boot device (e.g., F9) depending on your motherboard.
Choose your USB drive as the boot device.
You should see the Arch Linux boot menu, similar to this one:

Press Enter on Arch Linux install medium (x86_64, UEFI) .
After a few seconds, you will be in the Arch Linux live installation environment.

1.2: Partitioning with cfdisk

Next, we need to partition the hard disk to create a boot and root parititon. You can use fdisk, gparted or cfdisk. In this guide, I'll use cfdisk because it's convenient and provides an easy-to-use text-based "graphical interface".

If you have more than one drive connected, list all storage devices with:

lsblk

Now run the following command to open the cfdisk interface.
Select gpt as the partition table and press Enter.

cfdisk /dev/sdb

1.2.1: Create the Boot Parititon

In the cfdisk interface, select Free Space and press Enter.
Allocate around 512 MB to 1 GB depending on your needs. (.e.g., 1G or 512M) with capital G for Gigabytes and M for Megabytes
Next on the bottom options menu select [ Type ] and press Enter to open Partition Type/Filesystem menu.
Choose EFI System and press Enter.
Setting the boot partition table to EFI is essential because without it the firmware won't be able to locate and execute the bootloader.

1.2.2: Create the Root Partiton

Next, select Free Space again, then choose [ New ] from the bottom menu and press Enter.
Allocate the desired size for your root partition. If you plan to create a separate /home partition, allocate accordingly. In this example, we'll give 15GB to the root partition reserve space for swap partition.

1.2.3: Create a Swap Partition (Optional)

This step is optional, if you want to create a Swap Partition for your system then follow this or skip to next step.

Select Free Space then choose [ New ] and press Enter.
Allocate around 4GB (or as needed) and press Enter.
Next, with the Swap Partition highlighted, select [ Type ] and choose Linux swap partition type from the menu and press Enter.

1.2.4: Write the Partition Changes

This step is crucial, without writing the changes, your new partitions won't be created.

Navigate to [ Write ] in the bottom options menu and press Enter.
Type yes when prompted and press Enter.
Finall, select [ Quit ] to exit cfdisk.

1.3: Format the Parititons

Now that all required partitions have been created, let's format them before installing Arch Linux. First, run lsblk command to list all attached storage devices and their partitions. It's an easy way to identify partitions avoidformatting the wrong one:

1.3.1: Format the Boot Partition

Run the following command:

mkfs.vfat -F32 /dev/sdb1

1.3.2: Format the Root Partition

Run the following command:

mkfs.ext4 /dev/sdb2

1.3.3: Make Swap Area (Optional if you created a swap partition)

If you created a swap partition, run the following command (replace sdb3 with your swap partition name):

mkswap /dev/sdb3

Step 2: Updating & Synchronizing the Live Environment (Optional)

Before running the arhcinstall script, I need to cover a few preliminary steps to ensure it doesn't fail. You can skip ahead to the installation section if you wish, but if you encounter any errors, return to this step and try again.

2.1: Keys Activation

Run these two commands consecutively:

pacman-key --init
pacman-key --populate archlinux

2.1: Synchronize and Update the Local Package Database

Run the following command:

pacman -Sy

2.2: Update the Keyring

Run the following command:

pacman -S archlinux-keyring

2.3: Install or Update the archinstall Script

Run the following command:

pacman -S archinstall

Step 3: Install Arch Linux with archinstall Script

3.1: Run the archinstall Script

Finally, run the following command to start the installer:

archinstall

3.2: Mounting Partitions

Navigate to Disk Configuration and press Enter.
Select Partition press Enter.
Select Manual Partitioning and press Enter.

Choose the disk you partitioned for Arch Linux and press Enter, for me it's /dev/sdb.

3.2.1: Mount the Boot Partition

Select the boot partition created in Step 1 (Efi System) and press Enter.
Select Assign mountpoint and press Enter.
When prompted, enter the mountpoint and press Enter:

/boot

3.2.2: Mount the Root Partition

Select the root partition created in Step 1 (formatted as ext4) and press Enter.
Select Assign mountpoint and press Enter.
When prompted, enter the mountpouint and press Enter:

3.2.3: Confirm the Partition Layout & Exit

If you created additional partitions (e.g., /home), mount them now in the same way.
After moutning every partition, select Confirm and exit and press Enter.
Select Back and press Enter to return to the archinstall main menu.

3.3: Disable Swap in archinstall

Even if you didn't create a swap partition in Step 1, you still need to disable this options. Leaving it enabled can cuase installation errors.
From the archinstall main menu, select Swap and press Enter.
On the prompted options select no and press Enter.

3.4: Select a Bootloader

Select Bootloader and press Enter.
Choose GRUB and press Enter.

3.5: Set the Hostname

Select Hostname and press Enter.
Replace the default hostname (archlinux) with your desired hostname (e.g., MusaBase) and press Enter.

Enter a password for the new user and re-enter it to confirm.

When asked "if you want to make this user a superuser (sudo) ?", i am choosing yes.
Choose yes or no according to your needs and press Enter.

3.10: Configure the Network

Select Network configuration and press Enter.
Choose NetworkManager. If you select another tool, ensure it's configured for internet access in the installed system.

3.11: Install Arch Linux

I've left all other settings at their defaults such as the kernel and ecryption options beacuse i dont need them now. I'm not installing extra pacakges now, I'll add them after installation. Let's move on to the installation process:

Select Install and press Enter.
When prompted to confirm your configuration, chooseyes and press Enter. The installation will then begin.

3.12: Reboot

Once the installation finishes, you will be prompted to reboot.
Reboot now to begin the next phase:

After rebooting, you will see the GRUB menu with a few options:

4.1: Login with User Account

Select Arch Linux and press Enter.
After a few seconds, you will see the SDDM graphical interface with your local User's account which you created during the installation.
At the prompt, enter the password for your user and press Enter.

After a few seconds, you will inside your system.

4.2: Grant Sudo Privileges to Your Local User (Optional)

Note: Follow this step if you didn't add your user as Super-User or Sudo and if you didn't create your user with sudo then follow this step.

4.2.1: Switch to Super-User (root)

Open terminal by pressing CTRL + ALT + T.
Run this command to switch user to the suerp-user account. When prompted, enter the root password you set during installation:

4.2.4: Add your User to the Wheel Group

Run the following command:

usermod -aG wheel musabase

4.2.5: Change back to Local User

Now, that your user has sudo privileges, switch back from the super-user to your local account. It's best practice to perform administrative tasks as a normal user with sudo rather than as root.

Run the following command:

su username

4.3: System Update with Local User

Now that your user has sudo privileges, run a system update using sudo.

In the /etc/resolv.conf file, add the following line:

nameserver 8.8.8.8
nameserver 1.1.1.1

Next, press Ctrl + O to save chagnes then press Enter to apply the saves and then press Ctrl + X to exit the file.

Afterwards
