The easiest way to try OMOS is to download a ready-made image and boot it. There’s no installer to run and no account to create — an image boots straight into the system.
OMOS is an early preview. Booting it in a virtual machine is the safest way to look around and costs you nothing. Writing it to a real disk is for a spare machine you don’t mind dedicating.

1. Download the image for your chip

1

Pick your architecture

On the OMOS page, choose the image that matches your machine’s processor: x86_64 (most Intel/AMD laptops and desktops), ARM64 (many single-board computers and ARM machines), or RISC-V.
2

Download and unpack it

You’ll get a compressed disk image. Unpack it to get the raw image file for the next step.

2a. Boot it in a virtual machine

The quickest look. With QEMU installed, boot the image in a window — no changes to your real machine. OMOS starts on the screen and also prints to the serial console, so you can watch it come up.
A virtual machine is disposable: close it and nothing on your computer changed. It’s the recommended way to explore this early preview.

2b. Or boot it on real hardware

1

Write the image to a disk

Write the unpacked image to a USB stick or drive with an imaging tool you trust. This erases the target disk — pick the right device.
Writing an image overwrites everything on the chosen disk. Double-check you’ve selected the USB stick or spare drive, not your main disk.
2

Boot from it

Boot the machine from that disk (OMOS uses UEFI). It comes up the same way it does in a virtual machine.

What you’ll see

This early build boots into a system console rather than a desktop — the graphical shell is on the roadmap. What you’re looking at is a real operating system coming up on your hardware: bringing up the processor’s cores, its memory, and its protected user space. It’s the foundation everything else is being built on.
