I successfully installed MacOS Catalina 10.15.4 on my computer and it it starting up just fine from the USB.
I followed the steps from https://dortania.github.io/OpenCore-Des ... c2hdd.html. However, I still cannot boot without the USB.
At first, after I did that, I checked the boot options using EasyUEFI in Windows and found that there was no boot option for my HDD that MacOS was installed on as it did not seem to be recognizing the EFI partition. I then used Disk Genius to setup a boot option pointing to the EFI Partition I tried booting from the disk from the boot menu in the BIOS and it flashed the screen for a second and was back at the BIOS screen. Does anyone know why this is not working for me? I also attached my EFI Partition contents here for anyone to see:
