A boot CD of Hirens BootCD, DBAN, or any Linux LiveCD distro.

There's a command called wipe.exe that runs off a bootable CD that could do it. Or if you have a live linux distro, you could probably use dd.

or you could use fdisk again from a bootable CD to delete partitions. But if you have no data to save, I'd use dd or wipe.exe
