I have my hard drive dual partitioned. Copy of Windows XP Pro on each partition. One is my general mess about partition what has internet access and games installed, etc and the other partition is for audio software only. I've optimized the audio partition with the help of www.musicxp.net and it runs very very smooth and fast. When you dual partition your drive and install 2 windows XP when u boot your computer it comes up with a nice little menu asking u what partition you want to boot. Its a good idea to keep your general internet partition as the first lettered drive then keep your audio stuff on the last lettered drive. This is just incase old badly written software might write over the registry on the other partition, but u dont have to worry about that as much with newer written software.
