you can't just readily reformat a notebook hardrive, since most companie do not give you all the critical software that comes with the computer, or setup files for the hardware. Also by reformating the hardrive you also void the warrenty for your laptop.

If you were to upgrade from home to Pro, I suggest getting the pro upgrade, rather than having the full install (that's good if you are starting from scratch) I also suggest asking Compaq and inquire about making an upgrade of that type, (so if it screws up, it's there fault, and not yours). this is from my own experiences btw.
