Thanks, just two more quetions.. How is with dual installation of qubesOs and Windows and how is with privacy? I know that some laptop manufacturers preinstall some kind of spyware on their laptops to gather user data

Dualbooting is possible but not ideal: https://github.com/Qubes-Community/Contents/blob/master/docs....

Qubes doesn't preinstall any spyware. It provides privacy with Whonix: https://www.qubes-os.org/faq/#how-does-qubes-os-provide-priv.... If your BIOS is compromised, then it might be game over; coreboot is recommended.
