    So, Im trying to install windows 7 on a partion. When I hold down the option key during boot the USB drive(s) wont show, yet they work fine in disk utility and are shown in finder. What should I do?

    Yes, I went through Bootcamp assistance - dragged my "Windows7Ultimate.iso" file to the field and installed it, followed by a "successful installation"

    ----------


    The USB Drive is completely blank - I just formatted it through FAT-32.

    It could just be a poor quality or dying stick...Can you try another one?

    Do explain.

    Ive tried two different sticks, one of them is brand new. Neither works. My 2TB HDD works though - but its formatted in MAC Journal and wont work for PC, cant really bother to format that one and lose all data as Ive got a good 300 GB worth of material on it

    You shouldn't need to hold the option key down during boot to boot off the USB key.

    Bootcamp Assistant should have already set that drive as the next boot device.

    When you hold the option key down, it's bypassing anything that Bootcamp Assistant did for you.

    You may need to re-do the Bootcamp Assistant from the start, but first I would try just booting the system without doing any option key.

    I just tried this and it actually starts booting, though I get a black screen with a white message saying "No bootable device -- insert boot disk and press any key"
    Just like this guide; http://www.youtube.com/watch?v=NgWBY6IezQA

    He suggests trying a different USB Drive, which I have - I bought a brand new one just for making this boot possible, still no success
