please do not download it from 1337x.to cracked windows is not safe! Instead Download it from Microsoft's own website https://www.microsoft.com/nl-nl/software-download/windows10 then click on "download utility now" then choose download for another device for it to download as an iso file then after downloading put that file on a bootable drive and go to the startup manager by touching f12 or esc or f10 button depending on your pc brand then choose your flash as a boot device then it should get you to the setup menu. It should be easy and obvious after that!
