Hey there,
While trying to install Catalina in an Acer Aspire 5830T the following problems occured:
The OpenCore Bootmenu doesn't recognize my keyboard (Even external USB-keyboards doesn't work)
When the installer says "2 minutes left" it reboots, which is normal afaik but OC doesn't list a new bootoption. It boots directly to the beginning of the Catalinainstaller again.
I tried to copy the EFI-Partition from the USB Stick to my SSD manually, which then gave me a second option in OC. It was automatically selected but then it just boots into a black screen.
As a beginner in the whole Hackintosh topic, I kindly appreciate your help.
