Cautions

Keep these in mind before you commit any changes:

Data Loss

Writing the ISO to a USB drive erases all data on that drive
Installing to disk can erase existing operating systems and files.
Always back up important data before formatting or partitioning

Device Selection

Double-check the target device in your ISO writer (e.g:/dev/sdX)
Confirm the correct disk in the installer before proceeding
If unsure, stop and verify device names from another system

Legacy Hardware

Some very old BIOS implementations may not boot from USB reliably
Boot keys differ between vendors, check the on-screen hints
If the system fails to boot, test the USB on a second machine

Installation Overview

01

Prepare the USB

Download the Sagaris ISO and insert your USB drive. Open your ISO writer and select the ISO. Pick the correct USB device as the target and start the write process and wait for it to finish

02

Boot from USB

Plug the USB into the target device. Enter the boot menu or BIOS (by pressing F2/F10/F12/Del, etc. while the machine is booting up. The exact key depends on your PC manufacturer). Choose the USB device as the boot source. Select the InvictusOS live option in the boot menu.
