[Solved] Asus Maximus X, 8700k - Can only boot from USB stick into HighSierra, otherwise acpi error?

[Ed Ding]

Hello!

I installed everything according to guide + Storks MyHero Build.

The only thing is:

On boot, the Bios seems to constantly forget that I put Boot-Order #1 UEFI USB Stick.
If I then choose it again I reach the boot menu to choose which hdd to start from (Install macos; System SSD Hfs Sierra, Recover HD)

Choosing System SSD gets me into a flawlessly working High Sierra with 8700k.


If I directly boot from System SSD (Bios: UEFI, System SSD) I get an acpi error 6 table load failure...etc...


How can I make that work? I am not quite sure actually which EFI partition including kexts etc really loads up my working OSX and why...

Thank you

Replace the EFI folder from your SSD drive with the one from your USB stick.

• Mount the EFI partition of your USB stick
• Copy the EFI folder of your USB stick to the desktop
• Mount the EFI partition of your SSD drive
• Delete the EFI folder that is currently on the SSD drive and replace it with the one you copied from the USB stick.

My god, you are my hero. Speeds up booting tremendously!!
THANK YOU! This works now. Something seems to have failed when doing this the first time.

Still cannot understand why BIOS forgets the boot sequence setting each time but Im going to figure that one out.
