  Warning: no primary partition is marked bootable (active)
  This does not matter for LILO, but the DOS MBR will not boot this disk.

  The command to re-read the partition table failed.
  Run partprobe(8), kpartx(8) or reboot your system now,
  before using mkfs
  If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
  to zero the first 512 bytes:  dd if=/dev/zero of=/dev/foo7 bs=512 count=1
