into 2 operating systems of Vista. he said, one will have all the apps he installs wants on it, but the other will just have the operating system/office. is it possible to have 2 Vistas on this and what program should i use to partition it? i'm scared that im gonna screw his new computer up. if it was mine, i would be able to do it on my own but i have only 1 chance so i don't want to screw up.
