macOS Big Sur Cannot Be Installed On This Computer HELP!

Here's what it shows: https://imgur.com/a/Ngof99s and my EFI: https://drive.google.com/drive/folders/13d3xBUCM8UlyFIaHhOPdiREHqUsv6Ys7?usp=sharing. Here are my specs (although I think it will be useless):

CPU i7-6500U RAM SODIMM 8GBx2 DDR3L 1600MHz GPU Intel HD 520 + Radeon M335 Method OpenCore 0.6.3 macOS Version Big Sur Beta

I use the following command in Terminal, which partitioned my disk:
diskutil partitionDisk GPT APFS "Macintosh HD" 70% FAT32 WINDOWS 30%

I just pressed the Install button on the "Recovery Assistant" and this popped up.

Thanks for helping!
I solved the EFI problem here. Thanks for u/EmperorNeos
