Not installing

Hello! My NVMe is using APFS file system, and when I try to "re"install macos it gives me a black screen after about 3 hours of downloading. It clearly shows that it has downloaded since after the black screen disk utility says 12GB is used on the disk. I'm currently trying to install Big Sur with opencore. I have an intel i7 920, a rampage II gene and I have an RX 560 Series. Here's the efi: https://github.com/Justasadman/EFI-for-bloomfield/releases . What should I do?
