Nox OS

Before you install Nox.

What you’ll need, how to make the USB stick and how to make sure the image is genuine.

Requirements

64-bit PC (x86-64) with UEFI
Secure Boot can stay on
4 GB RAM or more (8 GB recommended)
12 GB of free disk space minimum; 50 GB or more is comfortable
USB stick of 8 GB or more — it will be erased

Write the USB stick

balenaEtcher (Windows, macOS, Linux): Flash from file → choose the stick → Flash.
Rufus (Windows): partition scheme GPT, target UEFI; choose “DD image” mode if asked.
dd (Linux) — double-check the device name:

sudo dd if=nox-os.iso of=/dev/sdX \
  bs=4M status=progress oflag=sync

Check the checksum

Compare the result with the SHA-256 published above. They must match exactly.

# Linux
sha256sum nox-os.iso
# macOS
shasum -a 256 nox-os.iso
# Windows (PowerShell)
Get-FileHash nox-os.iso

Installing next to Windows: back up your data first. The installer shows every partition it will change and asks before it writes anything.
