This isn't new. It's been this way for years in Windows 10, Windows 7, Vista, XP. If you have an unrecognized AHCI/SATA/RAID controller, you need to load the "F6 driver" This term itself goes back at least twenty years. Dell has frequently over the years shipped computers with drive controllers that weren't recognized by the basic driver set included on the Windows installation media. Also, Dell changed (many times) the default bios settings. Sometimes they come set to IDE (which will always work with default drivers). Other times, they have the controller set to AHCI or RAID mode (which will typically require a driver).
