My son is graduating from high school in the spring and will be entering college to study computer science. I plan to help him buy a new computer (mac pro) as a graduation present, as his current mac is getting a bit old. He loves Mac OS but really needs to run Windows as well. As I understand it, the new Intel machines can do both. What is the best way to do this? Partition the HD and install each OS on the same drive (is this what is called 'dual-boot')? Or use two harddrives and load one OS on each drive? Sorry about the noob question; this dual-system thing is a bit beyond my experience. Thanks.
