Put it on a USB stick.
The image is hybrid, so it can be written byte-for-byte to a USB drive (4 GB or larger).

Pick the ISO, pick the drive, flash. The simplest path on any operating system.
dd
sudo dd if=ruscalinux-1.99-amd64.hybrid.iso of=/dev/sdX bs=4M status=progress oflag=sync
Replace /dev/sdX with your USB device — double-check it, since
dd overwrites the target completely.
Live first, install later.
Boot from the USB stick and choose Live system (amd64) to explore without touching your disk. When you're ready, pick Start installer — or Start installer with speech synthesis for an accessible, spoken installation.
RuscaLinux has no live repositories.
You won't be nagged by daily upgrades, and nothing will silently change under you. To move to a newer release, you download the new ISO and install it fresh — the same clean, known starting point, every time.
