I've succeeded at last in making my Hackintosh dual-OS, with WinDoze 10 on one internal SSD and Mojave on another; the Win10 side has been up and running over 24 hours, installed some games, ran virus checks, did some personalising... now it's time to shut'er down and go back to Mojave-land. And now I'm facing a new problem. It's quite maddening.
The mobo is ASUS MAXIMUS XI HERO. The symptom is that when I reboot, no matter what UEFI volume I choose as #1 in the list of boot devices, the mobo always boots back into BIOS. What I see in the menu is 2 (?) UEFI boot devices associated with SSD number 1 (MacOS), 1 Microsoft Windows EFI boot associated with SSD number 2, Win10, and 1 bogus EFI device associated for some reason with one of my SATA drives.
The default boot device keeps reverting to Microsoft Windows EFI Boot (SSD 2). Also, the boot device list keeps reverting to empty, with the Microsoft EFI Boot listed as "Override." When I use F8 to invoke the boot menu, SSD 1 does not appear; only Microsoft Windows EFI appears. When I go into BIOS and visit the Boot configuration screen, the four options described above appear but don't seem to do anything.
I have (not sure how) at least once overcome this by sheer stubbornness: booting over and over again, disconnecting AC from the power supply, etc. But this afternoon I really got stuck. Booted about 12 times into BIOS, power cycled at least 2 times, before I gave up and plugged in my Mojave rescue USB stick. Ta-da! instant boot into Mojave. No pause in Clover, though!
So... what is to be done? I found some gripes online, two or three years old, about Asus mobos misbehaving and booting into BIOS... but no real answers. Some suggest memory could be at fault; I will run a memory diagnostic, but it seems unlikely I have bad RAM given the successful run-time of Windows and a few demanding game apps over the last 24 hours.
I carefully disabled Windows auto-update (first thing I did after booting it, just about) so this should not be a matter of WinDope whimsically reinstalling bits of itself and clobbering my EFI partition... but I'll check.
If anyone has thoughts on the cause of a mobo booting repeatedly into BIOS and ignoring the EFI partitions available to it, I'm all ears.
