Windows 10 installation stuck at 96%?

I bought Windows 10 for my laptop and already burned the system to DVD, now I'm in the process of downloading it…

After I have entered the license key and etc, a window appears with Windows Setup and the Windows files have already been copied, only when "Files are being prepared for installation" it sticks at 96% …

Does anyone have any idea what to do there?
