Seems Xubuntu 22.04 release just cannot detect EFI / UEFI support within the BIOS.
The Ubuntu / Xubuntu ISO DVD's seem to be intelligent enough to boot if the BIOS has only legacy support or new EFI / UEFI support. Perhaps that is the area of Ubuntu that has the issue... that the EFI / UEFI detector fails to detect, so boots in legacy support mode?
For this system, manually partitioning off the Live DVD with Gparted, msdos partition table, one large xfs partition mounted as root.
Thank you, Rod!
