UDNI boot to local hdd
on atleast UEFI based systems, the choice of booting from Local HDD makes the boot sequence hang.
So primary boot device cannot be the network.
This is a known limitation of any Operating system or BIOS.
Right now, we’re obligated to “legacy” network boot. If UEFI is enabled, “legacy” methods can’t exit back to UEFI models. So what ends up happening is the hdd, when trying to boot to hdd, is actually searching for MBR information which is non-existent on UEFI/GPT disks.
