Then do not use "-b" option. It is needed for BIOS boot. Do you need to get a system with both UEFI and BIOS boot? Then use two different partitions for UEFI and BIOS booting schemes. > gpart bootcode -b /boot/pmbr ada0 > bootcode written to ada0 This is needed only for BIOS boot and together with "-p /boot/gptboot" option. > gpart bootcode -p /boot/boot1.efifat -i 1 ada0 > <no output> Hm, I'm not sure if this is supposed (like: supported) to be done like this. One may use dd to copy this partition image (boot1.efifat) if target partition is not less then the file length. Otherwise one may format the target efi partition as an msdos-fat one, create /EFI/BOOT mountpoint and copy boot64x.efi file there. Here is a link from another similar thead: http://www.wonkity.com/~wblock/docs/html/disksetup.html#_booting_with_uefi > System is bootable.
