Can you boot the original install CD you used, exit the installer and check the output of: sysctl machdep.bootmethod This should either tell you BIOS or UEFI, and this is how the installer decides what kind of setup the booted system later will need.
Original install CD... as in 10.0 standard CD or "one used to install... years ago" ? That was lost in time... probably 9.0 or even 8.x
With the 10.0 install ISO amd64 the command you say yields machdep.bootmethod = BIOS Which is correct I believe, since UEFI is disabled in the BIOS. Riccardo
