How to run High Sierra on Opencore?

[msh]

I can boot macOS Sierra, Mojave, Catalina and Big Sur with Opencore. But, I can't with High Sierra.
I have : attempting system restart...mach reboot. What do I need to do to resolve this? Thanks for your help.

If Sierra boots, if Mojave boots, you are both sides of the HFS+ to APFS divide so disk format can't be the issue. What exactly is happening when you try to boot High Sierra? A Verbose screen would be useful. The error you mention is a very early state of affairs, usually.

(Ignore the NVidia GPU parts. Use your Sierra).

With OpenCore specifically it is important to clear NVRAM between different OS boots, otherwise settings from a previous setup will be left and may cause problems with the new.

Another example of older hardware, OpenCore and High Sierra here:

Hello everyone, I'm trying to give new life to this old mobo. CPU is an i7 2600K (Sandy Bridge), dGPU is an NVIDIA GTX 760. I created the High Sierra USB installer and followed (very very carefully) the Dortania guide for Opencore 0.6.5, but it seems that I cannot get past OpenCore's "End Random...

Yes, I have same hardwares. Right now, I use my second system. Thanks, I'll see Asus P8h67-M EVO High Sierra.
