-!!! info "Outdated with new installation method"
-	The video guide is currently outdated with the new installation method to install Atlas without a USB. If you want to follow along with it, it still works fine, and you can find the old method [here](/getting-started/other-installation-methods/usb/). However, if you want to install without a USB and still follow along with it, start from [9:55](https://youtu.be/GoO36Tj5TGE?t=596).
