    I've searched extensively and I can not find a straightforward answer that works.

    I've used my Windows 7 machine to make a USB bootable (command prompt, etc) using these instructions.

    And i've copied all of the Win7 files off of the installation DVD on to the jumpdrive.

    I've prepared my Mac for installation by installed rEFIt and all the other instructions on the following tutorial:

    So when I have my USB drive plugged in to my MBP and I start it up, holding down option to bring up rEFIt, the USB drive doesn't show up to begin installation.

    Is there something I'm missing here?

    Thanks for all your help!

    Even with rEFIt USB boot of legacy OSes on most Macs is flaky at best.

    If you can't use an optical disc and drive there are two reliable methods you can use.

    1. Use VM software (Parallels/Fusion) to get the files from the ISO or USB to the Boot Camp partition
    2. Follow the same general method you used to create a throwaway partiton on your internal drive to install from

    Both are detailed in this thread:
