(I was only able to capture them by taking a picture: https://launchpadlibrarian.net/227876135/IMG_20151128_230313.jpg) Then I keep trying, sometimes I boot into Windows inbetween, and eventually, the kernel comes up. Then, when running and putting a lot of load on the disk (e.g. running dump or a simple update via apt-get upgrade), the system looses its disk and I have to hard reset. The machine runs perfectly fine under Windows, so I don't believe it is a hardware issue. I hope there is a solution to this issue. best regards Carolin
