SOLVED: Problem with Asus Prime X299-A UEFI BIOS
I'll post this even though I'm not convinced anybody who can use the
info will ever find it here. It's just that I've received so much good info in this newsgroup over the years (primarily from Paul) that I want to give back if I can. My problem was that I'd installed three versions of Win10 on my new Prime X299-A setup and when I'd choose something other than my default OS using F8, all the boot options (OSs and optical drive) would get scrambled in UEFI BIOS. Once I'd picked an alternative OS using F8, I never could be sure exactly what OS I'd get upon reboot. (I don't use Boot Manager, want never to see it.) I explained this problem today to a tech via the Asus website chat feature and this is how he replied: This should do it: 1. Disconnect all the other drives from the unit leaving only the main boot drive. 2. Go to BIOS and under boot then go to OS type and set it as Windows OS. 3. Disable Launch CSM. 4. Save and Exit the and this should lock it as the boot device. After this you can add back the other drives and try the F8 option and see if it fixes the issue. Yes, I had to do a little investigative digging to find a way to set OS type as Windows OS, cuz the option wasn't exactly where he said it would be, but that's OK. Bottom line is that this worked: Now I can pick the OS I want by using F8 without worry. And the takeaway is that Asus Tech Support came through for me on the first try.
