Confirm. +Attach you hard Drive to MAC (do not assign to OS, leave it unmounted) +Create a new VM , choosing the final OS your external USB hard drive will boot. +Choose to 'customize' you VM after creation. +Remove the Hard Drive created by default +Add a new Hard Drive of type 'Boot Camp' +Location should show your attached bootable USB drive , choose it +Customize the other settings as needed (Net,Memory..) +Boot it. Note: it may be needed to change the 'Location' of your drive from IDE,SATA,SCSI... Please post your findings.
