Reset the system setup from RAID to AHCI -- or, make sure you're using the latest Windows 10 install media 
I've been trying to install windows 10 to my Dell inspiron 5502 laptop but it never gets past the first install prompt saying: "A media driver your computer needs is missing. This could be a DVD, USB or Hard disk driver. if you have a CD, DVD or USB flash drive with the drivers on it, please insert it now."  I've read that I may need to install the Intel Rapid storage technology drivers but when I download it and put it on a second usb drive it was not detected; "No device drivers were found."  I've disabled secure boot and RAID windows iso is on a usb 2.0 16gb drive Mostly been following advice from this thread [URL] But nothing has worked yet. Does anyone know how to fix this? Thanks
