Respectfully , I have faced the same problem; I have Fujitsu ESPRIMO E7936 and at the moment of turning my computer on. the Phoenix bios menu can not detects the hardware; first the Phoenix menu shows a window over to choose F 2 or F 12 and then a window tells"initializing" and then the the window 10 start working, the above process takes 45-60 seconds, I did not have such problem when I had window 7 Pro 64 bit, I do not know "Rapid Storage Technology (RST) driver" and I am not sure if it is compatible with my computer or to fix the above problem and I do not know which of the downloads options I must choose to install in following link:
https://downloadcenter.intel.com/download/25165I fear if I install the "the Intel® Rapid Storage Technology (Intel® RST) RAID driver version 14.6.0.1029, it would make worse or stops working my computer.
Unfortunately the Fujitsu Forum does not respond to our problem, thanking you.
