    I Was wondering if it is possible to install windows onto my Mac but Partion the memory using an EXT hardrive so i don't have to use up the memory on my Internal hardrive. Is this Possible or do i have to partion my internal HD.
    Also, will most windows Programs such as Windows Based Computer games and Programs such as Photoshop and Dreamweaver work off my EXT hardrive?

    Windows generally does not like to run entirely of of an external drive, so you will generally need a ~20 GB partition on the internal just for the OS, and any apps and data the need to be on C:.

    If you had not said games, I might have suggested a Virtual Machine install using Parallels/Fusion/VirtualBox, which can be entirely on the external drive.

    You'll need to reinstall the program. Windows applications/programs require writing stuff into the registry or it won't work.
