What to do when CentOS cannot be started with VirtualBox on Catalina

less than 1 minute read

As a result of putting VirtualBox in the Mac and trying to touch CentOS, there were some points that were stuck before the guest OS started, so make a note


  • macOS Catalina 10.15.6
  • VirtualBox 6.1
    • https://www.virtualbox.org/wiki/Downloads
  • CentOS 8
    • http://isoredirect.centos.org/centos/8/isos/x86_64/

Part 1 The installation is complete, but when you reboot, you will be returned to the installation screen.

It seems that the disc boot order needs to be modified …
I solved it by going to VirtualBox’s Settings> System> Boot Order and setting “Hard Disk” above “Optics”.

Part 2 During virtual machine startup, it terminates for an unexpected reason

When I was investigating, I could start it by adding VirtualBox.app in [Settings]> [Security & Privacy]> [Input Monitoring] on my Mac! Although the article hits, even if I add it in my environment, it does not solve it …
Finally, I solved it by going to VirtualBox’s Settings> Audio and unchecking “Enable Audio”.

Finally started

I hope it helps people who are suffering from the same phenomenon.
