I have a Dell PRecision T3600 workstation that I need to upgrade to WIndows 10.  I have upgraded all the firmware and drivers to the latest levels but the upgrade seems to be failing on the on board Intel raid controller.  I have read thru all the different posts on this and havent found anything that will work.   Any ideas of full proof way to upgrade this PC to WIndows 10?  I am using  the raid controller for raid 1.
