What was removed, Wubi (the "Windows Ubuntu installer"), isn't a "Windows dual boot tool", its an installation tool for Windows boxes that lets you install/uninstall Ubuntu through Windows Add/Remove programs and have your whole Ubuntu root filesystem in what appears as a giant NTFS file.<p>It doesn't really do anything for the dual-boot experience, it just changes the installation experience. Dual booting on Windows machines installed through the normal Ubuntu installer has always had pretty much the same experience as dual booting something installed through Wubi.
