IMO dual booting might have made sense before hard disks were cheap, but if you want minimum frustration (and have an open bay in your case) just pick up a couple of cheap hard drive swap racks (I use Vipower) and another drive for Linux. If you hose the Linux install, you can swap drives and get online for help. Swap racks are so handy if I only used Windows I'd still make all my drives removable.
