Installation crashes when attempting to install on UEFI and mdadm enabled system on existing GPT partitions

[Alaric]

Could use a guide to help ensure all partitions are assigned for uefi to boot properly. From what I've seen online I have created a proper BIOS boot partition, but failed to create an EFI partition.
