If a moderately-intelligent, moderately-literate beginner can't install your operating system, then your operating system (or at least, its user interface) is crap.
Edit: Just to be clear, I'm responding to the quote, not calling Linux crap. I run a combination of Linux and Windows machines and VMs and they're both very straightforward to install, a complete beginner can just click next / next / next and still get it working.
Distros like Slackware or Gentoo give you more complicated setups but they are designed for experienced users.
There are so many places online to get help with a Linux install now. If you stick with the main distros as most do for there first taste of Linux its really simple.
My decade's worth of experiences having to transfer over wired (wired!) NIC drivers onto computers that are completely supported by the average Linux distro because Windows doesn't ship with them strongly suggests otherwise.
Windows has thankfully gotten better about this lately (e.g. in the Windows 10 era), but the continued lack of drivers in the default install is really annoying when said drivers are for devices that virtually every free operating system supports out of the box.
Sidenote: I was really happy to successfully install it on the same disk as linux and not crap up my bootloader.
