+Description: Always copy partition table zone if floppy support is disabled
+ Do this even if no partition table is found.  Otherwise, the BIOS on Dell
+ Latitude E series laptops will freeze during POST if an invalid partition
+ table is contained in the PBR of the active partition when GRUB is
+ installed to a partition.
