XG Firewall SW-SFOS_15.01.0-376 install failure

Dear All,

Please be gentle with me.  My first post and first introduction to Sophos and the XG Firewall

I'm trying to install XG  SW-SFOS_15.01.0-376.iso  onto a Mini ITX Intel 64 bit system that was sold to me a while back,  the seller, a good friend, and very capable guy had used it for Sophos UTM without issue.

I took the machine, inserted a 64GB SSD and today tried the installation of  the XG product

All seems to be good.  I read on screen messages like:

Installing Loader for appliance SF01V_S001  [OK]

Installing firmware for appliance SF01V-S001 [OK]

Firmware Installed

Remove Installer disk

press y to reboot

SO I took out the CDROM and rebooted.

I get a PC BIOS error message   "No bootable partition"

I take out the disk into another system and sure enough

NO PARTITIONS ON THE SSD, ABSOLUTELY NOTHING!!

No wonder it did not start.

So the obvious dumbo question I am asking, is what the hell am I doing wrong?

Any other clear options to try?

Anybody?

Regards Marcus Bennett.
