Obviously the problem has been promised a resolution in this thread. All stall at some point in the process and do not complete. Have tried different flash drives and several different images. I am using a Win10 machine, bootable usb flash drive, Win7 iso copied. There is a half hearted attempt here with the tool to inject the drivers into the boot image. No doubt Intel should have seen this issue and frustration for consumers ahead of time and offer CLEAR documentation with a CLEAR path to to reasonably work the issues. Have spent WAY too much time on this issue. I have found documentation on the USB 3.0 and Win7 problem sparse and scattered. Like everyone else on the forum I am trying to solve problems, specifically mine is with a new NUC and loading Win7. First I would like to say thank you to Intel for keeping representatives available here to answer questions.
