    Hi guys!

    I'm trying to install Windows 7 Pro 64 Bit SP1 on a secondary SSD in my Mid 2011 21.5" iMac...


    The long story:

    But first...
    1. Old config and setup
    A. Mid 2011 21.5" iMac
    B. Not sure what OS I was on
    C. OWC 6G SSD 240 GB
    D. Seagate 7200 RPM HHD (not sure on any more of the specifics)
    a. 250 GB partition for Win7 - worked just fine
    b. Rest for iTune library
    2. Issue/Diagnosis:
    A. HHD failed and needed to be replaced
    3. Action/Treatment:
    A. Replace Seagate with WD Green 3TB HHD
    B. Remove DVD drive and replace with ADATA 240GB SSD via OWC drive cage
    4. All that to say: Was able to previously install Win7 and functioned just fine
    Installing Windows on new ADATA SSD:
    1. New config and setup
    A. See pic above
    B. OWC 6G SSD with OS X El Cap. (working just fine and not a new situation)
    C. WD Green 3TB HHD for iTunes library (working great)
    D. ADATA 240 GB SSD (freshly installed and working great... as a hard drive... not as a Win install drive)
    2. Process:
    A. Modified BootCamp.app/Info.plist via online guides; worked out just fine
    B. Had an old Win8 install thumb drive laying around and tried to install from it.
    C. Boot from Win8 thumb and attempted to install; got into Win8 installer but unable to install to any drive/partitions
    D. Trouble shot via internet and tried various solutions; none worked.
    E. Gave up on Win8 (never was able to get it to work in the past either) and went for Win7
    F. Downloaded 2 different .ISO files of Win7 Pro SP1 64Bit; Also downloaded proper files from Apple for BootCamp driver stuffs
    G. Used BootCamp to create a bootable thumb drive
    a. Drives used: SanDisk Cruzer 8GB; Also tried Toshiba 16GB ...GBRG01S
    H. Follow proper procedures for creating bootable thumb drives and copy BootCamp drivers to /root of thumb drives
    I. Use BootCamp to reboot to install Windows7
    J. Not able to find bootable drive
    a. Fix: Manual reboot and hold Option Key
    b. One of the iso's will show up and allow to boot; still gives no bootable drive
    c. Tried multiple combinations of ISO's +/- BootCamp drivers on said drive(s)
    d. Unable to boot into Win7 install software at all; only show's "no bootable drive"
    e. Curious... because Win8 thumb drive was able to get past this with the reboot + option trick
    What I ultimately want:
    1. Be able to boot from the ADATA SSD into Windows when I want to play my Steam Library
    2. Leave everything else the same.

    The Short Story:
    1. Replaced DVD drive in Mid 2011 iMac with an ADATA SSD and want to run Win7 or 8 on it. So far no luck. Help please.
