Smooth install (AHCI). Only problem I had (for about a year) until updating to BIOS 0452 was occasional no boot with memory set at 1866. Since updating to 0452, the system would not boot to Windows and none of my HD's (2 mechanical and 2 SSD) appeared as possible choices. Pressing F10 at boot would not do anything, it seemed as if it was broken. Optical drives were showing in Legacy so I would have to put the Windows 8 disc in the drive and let it boot from that to access Windows.
Tried going back to prior BIOS, installation would not initiate. Since I had a lot work to do, I lived with it for a few weeks until I had time to unplug everything, reset it. Tried enabling "Boot to UEFI shell. I can now boot to my Windows SSD drive by pressing F10. I suspect that some of the boot settings may have changed in this version or got reset. What is Secure Boot? Should I enable it? What does Boot to UEFI shell does? Should I keep it enabled or not?
Which settings should I use to boot directly to my (AHCI) C drive?
