Install the gdisk, parted, and kpartx packages: sudo apt-get install gdisk parted kpartxĮxtend the image so that there's room to add a new partition to it. Note that this process may render the image unbootable as a CD image. This wiki page provides instructions on converting an image so that it can also be used for booting on a hard drive. However, EFI booting is only supported on CDs, because the images include an EFI El-Torito CD boot block but do not include the EFI system partition required for EFI booting of hard drives. The hybrid ISO/USB images currently created by Ubuntu as official images can be written to either a CD or a USB stick, and they support both BIOS and EFI booting.
