Hi, fisrt excuse for my english, im spanish . I´m new using VB, i have win 7 ultimate, and i want to use and old joystick and an old printer, but yhese only works on XP. I just follow all the step of a tutorial, but when i continue with the installation of XP, there is a message that says that the installer (XP ps3) doesnt recopgnize any disc ( i have 3 320 GB sata discs). Plz some one help me

Instead of a tutorial, why don't you start with the step-by-step instructions of the official manual? Read Chapter 1.7 Creating your first virtual machine. I have a feeling that you confused virtual and real hardware. If that's that not the case, please explain in more detail what and how you are trying to do.
