As far as I know Intel HD 2500 isn't supported in macOS and macOS Catalina doesn't even support older Intel HD Graphics such as 3000 Series natively so I don't think you'll be able to get it to work. Mojave and Catalina need to run on GPUs that support Metal and older Intel HD Graphics lack that function.

The reason that you can use the installer is because that it doesn't need Hardware Acceleration to load the installer but once the installation is done you'll need a fully functional GPU to be able to use macOS.
