  • A PC to install Omarchy 4.0.6 on, with at least 25 GB of free space
  • A USB stick or external drive larger than 8 GB

  • A second computer to prepare the USB (the video uses Windows 11)

This tutorial takes about 7 minutes to complete.

This guide shows how to install Omarchy 4.0.6 on your PC, from downloading the ISO to your first login, and which installer options to pick as a beginner and why. It follows the video, with the exact keys, button names and options from the recording.

New to Ventoy? The Ventoy page explains what it is, and the Windows 11 Ventoy walkthrough shows the Windows steps in more detail.

Warning: this is a fresh install. It formats everything on the drive you select, and there is no disk partitioning or dual boot. Back up anything important first.

Before you start

You need a PC, a USB stick or an external drive larger than 8 GB, and at least 25 GB of free disk space. You will also need a second computer, or the same PC while it still runs its current system, to download the ISO and prepare the USB drive. The video does this part on Windows 11, because many people switching to Linux are coming from Windows.

A wired internet connection is the easiest and most reliable way to connect.

Step 1: Download the Omarchy 4.0.6 ISO

Open your browser and go to the official Omarchy download link, omarchy.org. Click Download Omarchy and your download should start. The video skips through the wait. When it is finished, go to your Downloads folder and you should see your Omarchy ISO.

The video also puts the ISO in its own folder, which is optional but keeps it easy to find. Right-click the ISO and click Cut. Go to This PC and the C drive, right-click, choose New, then Folder, and name it ISO. Open the folder and paste the ISO there.

Step 2: Download Ventoy

To make a bootable ISO drive, the video uses Ventoy. It turns your USB stick or external drive into a multi-boot ISO drive, so you can store multiple ISOs on it and boot from them.

Open the browser and go to ventoy.net. Click Downloads, scroll down, find the Ventoy Windows zip file and click it. Scroll down and find the Windows zip file again, then click it. Your download should start shortly.

Go back to This PC, double-click the Ventoy drive, then right-click and paste the ISO file. When the ISO file has finished copying to the Ventoy drive, close the window.

Step 8: Boot from the USB with the boot menu key

Shut down your computer and reboot into the BIOS or boot menu. Plug the USB into the PC you are installing on, then restart and tap the boot menu key right as it powers on. The key depends on the brand. Here are some common ones.

BrandBoot menu keyBIOS setup key
DellF12F2
HPEsc, then F9Esc, then F10
LenovoF12 (or the Novo button)F2 or F1
ASUSEsc or F8Del or F2
AcerF12 (turn on "F12 Boot Menu" in BIOS first)F2 or Del
MSI (motherboard)F11Del
Gigabyte (motherboard)F12Del

You could also check your motherboard's documentation. Keys vary by model. If yours does not work, check the manual of your computer or motherboard.

Tap the key, do not hold it. Tap it repeatedly right after you press the power button, with the USB already plugged in. The boot menu lets you pick the USB drive once, and the BIOS setup key opens the firmware settings, where you can change the boot order.

Acer: on some models the F12 boot menu must first be enabled in the BIOS. Press F2, go to Main, set F12 Boot Menu to Enabled, then save and restart. Lenovo: many models also have a small Novo button that opens a boot menu.

If the key does nothing: fast boot can use up your keystrokes. On a Windows PC, hold Shift and click Restart, then choose Use a device and pick your USB drive. To open the BIOS setup that way, go to Troubleshoot, Advanced options, then UEFI Firmware Settings.

The boot menu keys for Dell, HP, Lenovo, ASUS, Acer, MSI and Gigabyte are the ones said in the video. The BIOS setup keys, the Novo button and the Acer setting come from the manufacturers' support pages and other published lists: Dell, HP, MSI, Acer and the Gigabyte BIOS manual.

In your boot menu, locate your Ventoy drive. In the video, the first device shown is the Ventoy drive. Select it and press Enter.

Step 9: If you get the Secure Boot failure

If you see the error Verification failed: (0x1A) Security Violation, the video calls it the infamous secure boot failure. This is one of the Secure Boot errors, and the fix only takes a minute. Press Enter for OK. When it asks you to press any key to perform MOK management, press Enter.

Go down to Enroll key from disk and press Enter. The selected key will be enrolled into the MOK database. Make sure you select VTOYEFI and press Enter. Then scroll down until you see ENROLL_THIS_KEY_IN_MOKMANAGER.cer and press Enter.

Go down to Continue and press Enter. Choose to enroll the keys, scroll down to Yes and press Enter. Then press Enter again to reboot the PC.

Keyboard layout, username and password

For the keyboard layout, the video selects English. Then enter your username and hit Enter. Enter your password and hit Enter, then enter your password again so the installer can confirm that it matches, and hit Enter.

Check everything

The installer shows a review of your setup. Check everything to make sure it looks okay. If everything is okay, click Yes.

Choose the drive

Here you need to be very careful. Make sure you select the correct drive that you want to install Omarchy on. The screen shows the Ventoy drive and also the hard drive, and the video selects its hard drive. The video is not setting up a dual boot: it formats the whole drive, erases everything and starts fresh. Also make sure to back up anything important before you format.

The Omarchy installer Select install disk screen with the available disks listed.

Select your drive. The installer confirms that everything will be erased, and you click Yes to install.
