Hello.

I have the same problem. I am trying to install KDE Neon 5.18.5 alongside my windows 10. I tried two times user edition with DVD and then LTS with DVD. At the same point installation crashes. I also tried to put North America - New York as the timeline, installation crashes again. I have Lenovo G40 computer with AMD Radeon graphics card and Core i5 intel processor. I tried the ubiquity procedure but got as a message that my dvd was not from original distro. Is there any way I can install KDE Neon 5.18.5 on my computer along with windows 10? Thanks in advance.
