The message about the kernel using the old table, appears because you are trying to modify partitions on a disk that's in use by the system. Either boot from a LiveCD and make the changes you want on your disk or, as Rinzwind said, do a clean install.

If this disk is not your system disk, you can also unmount it before you start making this kind of changes.

If it is, reboot as instructed by fdisk for the changes to be used.
