Laptops without OS

No preinstalled OS

— laptops shipped without full operating system. This category includes both models that do not have an “OS” at all, and devices with DOS preinstalled: this system is free, but it does not have graphical interface and is intended only to check the performance of laptop and install full-fledged OS on it.

Anyway, you should pay attention to this option if you want to choose and install the OS at your discretion, without relying on the choice of the manufacturer and without overpaying for an unsuitable system. Separately, we note that such equipment is not found on Apple laptops in principle: all laptops from this company come with pre-installed macOS.
