Latitude 7490 switched from AHCI to Raid On
Hello! I have a Latitude 7490 and it works fine. But today I mentioned, that the boot to Windows is slower (with 8-10sec). In BIOS setup I found the Raid On option working, which was original on AHCI. Why? How is it possible? I found a youtube video, which presents the switching back to AHCI without renistalling Windows and it works, but the system starts still slower :( What can I do? How can I avoid this after a reinstall?
