Inbetweenie option: Wubi. Installs (and uninstalls) like a normal program under Windows with no repartitioning required, but boots into it as if you had installed it more traditionally. Apparently there's a slight overhead from some sort of I/O emulation, but I can't say I've noticed it (although my project's heavily dependent on CPU and barely touches the disk). I certainly can't imagine it's worse than that under VirtualBox.

I've wondered recently if it'd be possible to persuade VirtualBox to boot that image under Windows without breaking anything.
