Nevertheless, I seem to be using /boot/pmbr as the You don't need /boot/pmbr nor any other MBR for UEFI booting. The UEFI BIOS does not care what's in the MBR, all it needs is a GPT with an efi partition. But maybe it's safe to have a pmbr after all, in case you attach your disk somewhere else, where a stupid "Disk Doctor" can be surprised by the absence of an MBR. > actual boot code and I have the GPT image being created with mkimg(1) whi= ch > gets dropped into the iso by dd(1).=20 Oh, I did not even know about mkimg(1). When I needed a disk image, I would mount a file via mdconfig. Thank you for this information, because mkimg seems to know many image formats (vhd, vmdk...), not only raw.
