Unable to Launch Linux OSs

Dear Sir/Madam,

I purchased a Boot Runner license on 9/21/2017. My computer has two disks running different macOS versions. In addition, it has a Linux-dedicated disk, another disk with two partitions for two other Linux distros, and a removable disk that I use for storage. The problem I am experiencing is that Boot Runner is only recognizing the two macOS disks. By “recognizing” I mean that it can launch those two OSs. That is not happening with any of the Linux distros, though. I can see the Penguin icon and click on it, but I get a blank screen after the computer re-starts. The screenshot below shows how I configured Boot Runner with one of the volumes. I first tried with all the volumes separated by commas, but that did not work.

The lines below illustrate the configuration of my disks and volumes.

/dev/disk0 (internal, physical):

If you could shed light on this matter, I would appreciate it. Thank you.

Currently, Boot Runner only supports Linux in Legacy, not EFI, mode. We are working on Boot Runner 3, which will allow you to specify EFI or legacy boot mode for each OS.
