Linux install

Hi guys just a quickie, im thinking of buying a laptop but windows will already be installed im on a course at moment and im doing security.
is it possible to take out windows entirely and then say install fedora 23 a virtual machine running Kali 2.0 and if this is possible what complications would i expect to come across just for taking out windows and installing fedora. Thank you

So you want to:-

a) fully remove Windows
b) Install Fedora 23 as the main S
c) install Kali as a VM in Fedora

Depending on the laptop spec you should be fine.
