Mini PC AMD Ryzen 7 5700U - Need Installation Help

[Cosmix]

I have now installed Windows on the other HDD. Copied the Microsoft folder to the Opencore but it still starts with an error message

NO.

When configuring a PC with multiple storages (HDDs, SSDs, NVMes, etc) you should follow these steps :

Power off the system.
Remove all the storages.
Power on the system.
Enter BIOS , load Defaults Options, Save&Exit.
Enter BIOS and setup every thing needed by macOS, Save&Exit.
Power off the system.
Connect ONLY one storage related to macOS.
Insert bootable macOS USB.
Power on the system.
Install macOS, test it.
Power off the system.
Physically remove the macOS's storage (make a note where it was connected).
Connect the second storage ( only this one, for Windows )
Insert bootable Windows USB.
Power on the system.
Install Windows, test it.
Power off the system.
Connect the macOS storage to its place.
Power on the system.
Enter BIOS and setup boot order ( the first option should be macOS ), Save&Exit.
At picker menu, choose one of the options ( macOS, Windows )

This way, each OS has its own storage and should evolve in a safe manner (without interferences).

Bottom line :
When installing any OS, its storage should be the ONLY one connected !
There is no need to copy/move data between the EFIs belonging to different systems.

I hope this is clear enough for the overall/whole process.

Adapt this procedure to your environment.

Cheers

In a multi boot system, if Windows is a member, you should "force" Windows to use UTC.

Configuring Windows to work in UTC​

Configuring Windows to work in UTC

If you work with multiple operating systems, then configuring all systems to work in UTC can be useful in avoiding time problems. This will allow you to keep the same time on all systems, which will simplify working with files, messages and other data that contain timestamps. Configuring Windows

Sorry could not answer earlier the translator has given me a lock here.

Hello and thank you for your detailed instructions.

I have implemented this 1 to 1 and completely deleted both hard drives and then did it as you wrote down. (I had enough time)
With the same result as before.

Windows starts for 2 seconds and then crashes.
