It loads into RAM. That's where OSes go. All of them. Either you don't understand that, or you're being obtuse. It's bootstrapped from USB. And that's not a good solution, even if it would boot from a modern sized stick (which it doesn't). This may be acceptable in your world, but I'm an adult, and I can afford adult equipment. I just spent $15 at microcenter to get the smallest USB drive that I could find of reasonable quality, and it's not compatible. ...Can't install on a drive larger than 32GB... Give me a break. My $8k server's OS is running on a nickel's worth of silicon... Not a great first impression, from either the software, nor the moderating staff.
