USB Boot & Install Guide

Run O OS on any PC or laptop in about 10 minutes — no technical skill needed.

1Download the O OS ISO

Download the latest O OS image on any computer:

⬇ Download O OS (latest ISO)

You need a USB pen drive of 2 GB or larger. Everything on the USB drive will be erased.

2Write the ISO to your USB drive

On Windows:

Download the free tool Rufus (rufus.ie)
Open Rufus → select your USB drive → click SELECT and choose the O OS ISO
Click START. If Rufus asks, choose "Write in DD Image mode"

On Mac / Linux: use balenaEtcher — select the ISO, select the USB drive, click Flash.

3Boot your PC from the USB

Plug the USB drive into the PC/laptop and switch it on
Immediately tap the Boot Menu key repeatedly:

Brand	Boot menu key
Dell	`F12`
HP	`F9` (or `Esc` then `F9`)
Lenovo	`F12`
Asus	`Esc` or `F8`
Acer	`F12`
MSI / Gigabyte	`F11` / `F12`

Select your USB drive from the menu and press Enter
O OS starts in about 30 seconds — no installation required to try it

If the USB does not appear: enter BIOS setup (usually F2 or Del), disable Secure Boot, save and retry. O OS boots on both UEFI and legacy BIOS machines.

4(Optional) Install to your hard drive

Want O OS permanently, so it works without the USB drive?

Right-click the desktop → Install O OS
Select the target disk, choose a disk encryption password, and confirm
Wait for "Done", remove the USB drive and reboot
At every boot, enter your encryption password — your whole disk is protected with LUKS2 full-disk encryption

Warning: installing erases everything on the selected disk. Back up your files first. O OS is beta software — use a spare machine if possible.
