Another alternative is my favorite app VMWare. You can format your entire hard drive fully NTFS with your main OS {XP or whatever}. When you use VMWare, or to a lesser extent VirtualPC you can have a virtual machine on your host machine. =D> The virtual machine's harddrive is a file on your host machines harddrive. Your virtual machine uses part of your host machines RAM, network connection, and everything else you have. VMWare even came out with a VMWare player that will run preexisting VMWare or VirtualPC virtual machines.

With these you can have as many different virtual boxes as you want. Currently Microsoft's VirtualPC only supports Microsoft OSs, go figure. VMWare supports all Windows {I have a DOS virtual machine}, Lindows, Linux, Novell, & Solaris - which didn't go over too well but they say it is experimental.

I can't say enough about this product.
