Hi Ruben -
I have the DC3217IYE NUC and I installed the 0048 BIOS with no luck. Then I set Intel Dynamic Power Technology to OFF in the BIOS and that solved both the Win 7 blue screen issue and SSD boot problem. Also, for what it's worth, I set the video memory size to 64MB and it won't boot if set any higher, and I disabled legacy USB.
