Dos. Should it stand?

Question

DOS

I'm not good at installing and configuring the system, please do not offend.
When I installed Windows, I accidentally deleted Dos. Windows installed, but doubts gnaw. Nothing will happen without Dos with the laptop?

Answer 1

... One example of a cumbersome and, according to the authors, useless add-on is the integrated WINDOWS system from Microsoft. This system occupies almost 1 MB of disk memory and is designed for primary use in conjunction with a device such as a mouse ...
...Thus, the reader has already understood that among the DOS add-ons there are quite useless systems that only look beautiful, but actually take the user's time, disk space and computer RAM. The deceptive beauty of such systems, however, has a strong effect on inexperienced users who have not had experience with the machine. The inertia of thinking is so strong that the authors had to observe how people who started working with such a setting, subsequently hardly force themselves to study DOS commands ... I would like to warn readers against this mistake ...

Without DOS, a penguin will settle on a laptop. Just like that, he will come and settle :) Turn it on once - and there HE! :D
