Hi,
I am trying to install CentOS 8 on my 2019 MacBook Pro 2019 with Catalina 10.15.4. I want to dual boot either with Catalina and CentOS.
Steps so far:
  1. Partition with 500GB for CentOS
  2. Created a bootable USB Stick with CentOS
  3. Installed rEFInd
I tried the same USB-Stick on a MacbookAir 2013 with Mojave and had no problems(When restarting I could boot from the stick and it showed me the screen to install CentOS 8).
Booting from external drive is allowed.

When I press the ⌥ Option while restarting, I can choose between my normal start volume and the USB Stick.
When I choose the USB, the MBP starts the Boot recovery System and I receive the message: "That start volume is not verified."
How can I get it to boot CentOS?

Best
