attempted to fix usb, now I can't boot into Catalina, can see EFI via windows. Help please.

Hey everyone, first off thanks. Here's what I've done. I installed a new PCI USB 3.1 card, didn't read, I tried to add a couple kext files and somehow compromised everything. I can't boot into catalina, or recovery, can't boot verbose, or safe mode. (no USB backup...) I have a dual boot machine so via "explorer ++" I can view my EFI folder and make changes, I now have access to my EFI and plist, so I've read not all is lost....

At this point I have no idea what to look for, what kexts should/shouldn't be and how/why I compromised my build. Any help would be fantastic. Honestly, I'm in over my head and not sure what files would be of help, please let me know and I can provide. Thanks again!

EDIT: Not afraid of a clean install, I cannot install a new version of Catalina, the USB install falls at first apple load screen, in boot.

BUILD: dual boot win/mac
