general question concerning dual-boot WIN and ubuntu

[Rosika]

Hello everybody,

 

 

As far as the topic of Linux is concerned I have a question of a more general nature.

 

I´ve got two computers, a PC and a laptop.

The PC is a Lenovo H520e and the laptop is a medion Akoya E6222.

The PC has WIN8.1 Home (64bit) and the laptop has WIN7 (64bit) as operating system.

 

What I want to do is turn both the PC and the laptop into dual-boot systems.
The second OS should be Linux Ubuntu, preferably 14.04LTS (64bit).

My question now is:

 

Could there be any danger or risk for the respective hardware when using a Linux-driven
system on a PC/laptop that originally was sold with a pre-installed version of Microsoft´s operating-system?
I mean is Linux alright for existing motherboard,RAM, fans etc?

 

I just want to be on the safe side before applying any changes.

 

Thanks a lot in advance.

 

Greetings
Rosika
