When the (first) instal from the actual Mac was done I was not there (blame 
youtube), my install was from a Compaq Presario M2000 (without a HD) when I did 
the next install with user I didn't "see" anywhere a choice to EFI or Not EFI, 
but iot did fry the Mac's boot with a grub error (cured in the usual way, ask 
if you need this) if I had a MAC to hand I could play and (probably) get the 
thing working
