macOS + Win dual boot (at same disk) with OpenCore

[cguo2016]

Same issue here with any solution found
Any one with any idea ?

I have the same issue as well, dell precision 5510. windows 10 is installed first with EFI size>200MB; after install Catalina 15.7 I copy OC folder into same EFI folder and use bootstrap.efi as a boot entry in BIOS. I can boot into windows10 from BIOS "Windows Boot Manager", but
