Hello Len 1; Yes, we are using the MBR Partition table 2; the PreP partition is 8MB and has the Boot flag set to on 3; Debian is running on bare-metal, no hypervisor involved 3; Correct, the installer boots with no issues at all and it's only after the reboot when try to boot the installation from the HDD that both bootloaders just stall/fail 4; We are using a 1GB USB Memory stick as the installation media 5; we are using the Debian 10 SID NETINST for PPC64 dated 2020-05-30, the reason we're not using the latest snapshot is because the latest one (2020-10-13) fails with 'missing-firmware /dev/.udev missing firmware' and the installation media fails to mount
