What am I doing wrong? Can't gpart(8) write both the pmbr and the efi
image as a single command? Is it an off-by-one error in gpart(8)?

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 ada0This 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.HTH -- WBR, Boris Samorodov (bsam) FreeBSD Committer, http://www.FreeBSD.org The Power To Serve

Is it an off-by-one error in gpart(8)?Hi, it looks like the problem is related to VTOC8 bootcode writing. I will fix this after weekend. Thanks for the report. -- WBR, Andrey V.
