Configuring Omarchy on Beelink

The following walks through my installation setup of Omarchy onto my new Beelink SER5.

I loaded the ISO onto a USB using my Mac, so this is a specific recount with these items in case it clarifies anything for others configuring their setup.

I will reference any point where it is best to refer back to DHH's video or the archlinux docs.

I operated most of this with my overbearing work laptop settings, and so admittedly wasn't able to visit the website documentation directly due to their strict policies. I am sure they are very good.

Preparing the ISO on a bootable USB drive

The following is best done alongside the archlinux installation documentation.

First, download the Arch Linux ISO from the official website. The official docs recommend using a BitTorrent download, however (due to work restrictions) it was required for me to make a HTTP direct download.

For myself in Australia, I found a mirror website to download the ISO directly, and then made use of the b2sum CLI utility in order to verify the BLAKE2b checksums.

To do this, download the b2sum.txt file from the downloads section into the same folder that you downloaded the ISO and run b2sum -c b2sums.txt in order to validate the ISO checksum.

  • b2sum is a command-line utility for computing and verifying BLAKE2b checksums.
  • BLAKE2b is a cryptographic hash function that's faster than MD5, SHA-1, and SHA-2, while providing high security. It's used to verify file integrity by comparing computed hashes against known good values.

On macOS, you can use tools like dd or graphical utilities like Balena Etcher to create a bootable USB drive.

# Example using dd (replace /dev/diskX with your USB device) sudo dd if=archlinux.iso of=/dev/diskX bs=4M status=progress

Always verify the USB device identifier with `diskutil list` before using dd to avoid overwriting the wrong drive.

This is also listed on the archlinux USB flash installation guide under 1.3 In macOS:

dd if=path/to/archlinux-version-x86_64.iso of=/dev/rdiskX bs=1m

**Take note**: the `of` section prefixes the disk with `r`.

dd (data duplicator) is a low-level copying utility that reads from an input file and writes to an output file. The options used are:

  • if= (input file): specifies the source file to read from
  • of= (output file): specifies the destination to write to
  • bs=1m (block size): sets the read/write block size to 1 megabyte for faster copying
  • rdisk prefix: on macOS, this accesses the raw disk device for faster performance

The command provided by archlinux will run silently. You can press Ctrl + t to get updates.

Once the USB is loaded, you can dismount the disk and we can plug it into our Beelink SER 5.

Since I pulled out my Beelink SER 5 fresh from the box, so it came preloaded with Windows 11.

We don't care about that preloaded OS, so we need to boot into UEFI.

You may be more familiar with BIOS. They are different technologies that do the same job.

  • UEFI (Unified Extensible Firmware Interface) is the modern successor to BIOS. It provides a more advanced interface with better security features (like Secure Boot), support for larger hard drives (over 2TB), faster boot times, and a graphical interface instead of text-only menus.
  • BIOS (Basic Input/Output System) is firmware that initializes and tests hardware components during the boot process. It provides the interface between the operating system and hardware, allowing you to configure boot order, hardware settings, and system parameters before the OS loads.

To enter UEFI on the Beelink SER 5:

  1. Power on the device
  2. Immediately press and hold the Delete key (or supposedly F2, but I didn't try) key repeatedly during startup
  3. This will bring you into the UEFI setup menu
  4. Navigate to the boot options and set your USB drive as the first boot priority
  5. Save and exit to boot from the Arch Linux USB

You should be able to identity the USB drive from the description. If it's confusing (mine was), then you can validate the drive based on your brand online.

Running archinstall

At this point, the system will boot into a very basic terminal UI. For most of this section, I followed along with DHH's setup tutorial.

We want to run archinstall to open the Arch installer and setup our configurations.

I won't go too deep into this section since you can follow along with the video, but the general overview is this:

  1. Run the Arch bootscreen
  2. (optional for Wifi) Configure WiFi with iwctl
  3. Open the archinstall TUI with archinstall
  4. Go down top-to-bottom on the left-hand sidebar
  5. (optional) Configure your locales
  6. Select your mirror regions to install from somewhere close to you
  7. Disk configuration with the default layout and using the recommended btrfs file system
  8. Turn on disk encryption (a must for Omarchy) -- select type LUKS, set the password and apply the encrytion
  9. Setup hostname
  10. Set root password
  11. Add user account
  12. For Audio, use pipewire
  13. For network configuration, copy over what you used for install
  14. For "Additional packages", ensure wget is installed as it will be used for Omarchy
  15. Save and run the installation

At this point, the installer will take over and it can take a few minutes for everything to e configured.

In DHH's overview video, his load time was wickedly fast. Not sure what gear he is working with, but I am very jealous.

Once you've configured archinstall and run the installer, it will prompt you to restart the system.

The following sub-headings are some details that I thought I would callout which goes a little bit deeper than the video:

archinstall

archinstall is Arch Linux's official guided installer that provides a text-based interface for installing Arch Linux. It simplifies the traditionally manual installation process by offering:

  • Automated partitioning and filesystem setup
  • Package selection and installation
  • Bootloader configuration
  • User account creation
  • Network configuration

bootloader

A bootloader is a small program that loads the operating system kernel into memory during startup. Common Linux bootloaders include GRUB and systemd-boot. The bootloader handles the transition from firmware (BIOS/UEFI) to the operating system, and can manage multiple OS installations on the same machine.

btrfs

Btrfs (B-tree file system) is a modern copy-on-write filesystem for Linux that supports advanced features like snapshots, checksums, and built-in RAID. It's designed for fault tolerance, repair, and easy administration.

zstd

Zstd (Zstandard) is a fast compression algorithm developed by Facebook that provides excellent compression ratios with high speed. It's commonly used for filesystem compression and package compression in Linux distributions.

wget

wget (web get) is a command-line utility for downloading files from web servers using HTTP, HTTPS, and FTP protocols. It supports recursive downloads, resuming interrupted transfers, and can follow redirects. The -qO- options make it run quietly (-q) and output to stdout (-O-) instead of saving to a file.

Installing Omarchy

Once the system reboots, you'll be prompted to unlock your encrypted disk and then log in with the configurations that you setup before.

If you're like me and normally map `caps` to `esc` and pulled an uno reverso on yourself to configure the wrong encryption passphrase for the drive, you'll need to make use of `sudo cryptsetup luksChangeKey /dev/YOUR_DRIVE_NAME` in order to reset the password. You can use `lsblk` to find the `TYPE=crypt` block device.

In the previous section, we preemptively configured wget. We can now use it to install Omarchy.

wget -qO- https://omarchy.org/install | bash

At my time of installation, this will prompt you for your password a few times and request some configurations for Git.

Afterwards, it will just do it's thing and install DHH's opinionated setup.

Once completed, you will be prompted to restart the system to apply the changes.

Congratulations, you have now configured Omarchy!

I use Arch btw

Conclusion

In this recount, we walked through how I configured my new Beelink SER5 for Omarchy with boot loading. This made use of my Mac for downloading, validating and configuring my USB drive for the Arch Linux ISO.

Hopefully this comes in handy for anyone else who may be keen to make the jump but wants to understand a little bit more about the configuration.

At this point, it's worth restarting DHH's video for the basics on how to work with Omarchy.
