    So i didn't know where else to turn to, I read tons of forums and watched videos and stuff, and now I'm stuck. I set up the partition and installed windows 7. i gave 32gb to windows and am running it off a usb drive that is 320gb. it install successfully and restarted my computer. but then it restarted into a black screen where it said could not find disk partition or something. found the solution online, turned it off, turned it back on holding option. and now I'm back to IOS. but whenever i try to start my computer back up in windows, it can't find the usb drive to load from in the home screen. I read on another forum i believe from here that said to download "rEFit" cus something about it not being formatted right or something?... and i ran the analyze thing and it gave me this:
    *** Report for internal hard disk ***

    Current GPT partition table:
    # Start LBA End LBA Type

    Not sure what it means and what or where i should go from this, but any help would be appreciated. :/ why is it not showing up on the home screen load up even when i hold "option"?

    easy replay would be - because MBP sucks at BOOTING stuff from USB. Especially windows 7 install's even created with BootCamp.

    But Loading windows 7 from and EXTERNAL....

    Recently I was researching and some people claimed that MBP wasn't supposed to boot stuff from USB drives first hand at all... So I suggest looking for other solutions for having Windows with you.

    Currently I'm exploring "MAC INSTALL WITHOUT USB AND CD" - VIA. - CLONNING a VIRTUAL INSTALL of WINDOWS on to your HARD DRIVE... But personally got stuck after all the procedures.:)

    So good luck to you.

    So you're trying to install Windows 7 onto a 32gb partition of a 320gb external USB drive?
    USB 2 or 3?
    What kind of Mac?

    With Windows 8 it should be a fairly straight forward procedure.

    With Windows 7 I'm not even sure if it's possible.
