  • ArcaOS 5.0.6
  • Installation Issue

ArcaOS can not be installed due this error on the installation phase.

Explanation
It seems to be a issue related to UEFI CSM. The same error message shows on older Mac Books with a CSM in the UEFI firmware. Seems to be an issue on the "MemDisk" component.
Workaround
Remove the HDD device from that machine, install ArcaOS on a different machine with that HDD and reinstall the HDD back on the original machine.
Additional Comments
It seems this issue may be solved on ArcaOS 5.1 with formal UEFI support.
