This is on a macOS Sierra 10.12.3 MacBook Pro [Host] running VirtualBox 5.0.32 r112930 with a Arch Linux [Guest]

Any ideas what is causing this error or how it can be resolved? Is this a known bug and/or does it need to be reported as a ticket?

Thanks, I wasn't sure where to place it, as I felt it was related to both and couldn't find a troubleshooting section.socratis wrote:I deleted your duplicate post from the "OSX Hosts" section. Cross-posting is not allowed per forum rules.
What do you mean by that? That the error is as temporary as it gets? Does you guest boot after that? Why do you need EFI to begin with?CyberManifest wrote:Getting an error on boot for a flash of an instance
