Hi Schele, did you already solved your boot problem? I'm very interested in your solution. I got a big bad boot problem too and I try to solve it since 6 weeks: I added a Samsung SSD 850 EVO and the S2000 D worked fine for two weeks. Then the misery begun, I got "blue screens of death". The blue screens returned every time more quickly, at last only 1-2 minutes after successful boot of Windows. But nearly always the system only started into BIOS. At these times the Intel SSD was "not present" in BIOS SATA configuration, but the 850 EVO. I had to remove the power cable to get a proper boot into Windows. So I thought, the Intel SSD could fail. But surface test and S.M.A.R.T. parameters of the Intel SSD were always ok and never there were data loss! Medion support adviced me to recover Windows, but it's hard to save my personal files when system always hangs and reboots... After reading many forums I found a description that there could be a problem with Intel Rapid Storage driver on Intel NUCs. So I uninstalled it and Windows replaced it with its own driver. The blue screens of death did not return and the S2000 D worked very well - but only for one week! Then the blue screens returned like the first time. So I decided to remove the 850 EVO to test if the 850 EVO could cause the problems. Now same procedure: The blue screens of death did not return and the S2000 D worked very well - but only for one week again! Then the blue screens returned like before. Now I'm about to try to save my files and recover Windows, but I'm in fear it will not work too. CU Jens
