prohibitory sign when loading to the installer

[densimpson]

My NUC8i7HVK was installed the Hackintosh before...but for some kind of reason, I have formatted all my ssd, update the bios to 0067 and re-install windows only in the early aug(1 for 970 Pro 512 for Mac and 1 x other 512Gb SSD for Windows before).

And recently I want to reinstall the Hackintosh, but now when I start running the install of Mac OS, it will show a prohibitive sign.

Some times I need to use CMD bcdedit command to remove the OpenCore, so I could boot from the usb, I thought it was the OS problem so I have formatted all my ssd and removed the Windows, but now I can't even install the windows 10 and without the CMD I can't boot from the USB.

I was just following the installation guide to create the usb, may I know how to solve this problem?
