Both Windows and Ububtu will install their own bootloaders. You may need to use the Mac OS X disk utility to delete the Mac OS partition, as eXplicit mentioned.
Right, you need to use the OS X installation to actually read the Mac Journaled partition so it can be deleted. Then, without having any partitioned space, you can reboot the PC into the Windows Installer and you can create the Windows Partition.
