Help with Bootcamp / Win 7 install... No superdrive available!

I have an iMac with no superdrive, which is making life very difficult for me! I am trying to find a way to install Windows.

I have a genuine Win 7 Ultimate disc, 2 internal drives (in the iMac), two external drives, two thumb drives, and a MBP w/ working Superdrive at my disposal. I also have a MBA USB Superdrive.

Can someone please help me get Windows installed on the iMac using some combination of what I have available? I feel like I've tried everything...

Thanks!

 

Yes I have. It cannot boot from USB. I get a "No bootable device found" error. Its very annoying.

I've tried USB Harddrive booting, Using a USB external DVD drive, using a thumb drive, hacking plist files, using Target Disc mode with another computer, winclone, gdisk, fdisk.... I'm starting to feel very helpless.

 

I was able to successfully do it by installing windows on my MBP, and then Wincloning it to iMac

 

Nope. No need. I installed windows, but never finished the installation. I got to the point where it needed to reboot, then shutoff computer, booted into OSX, made the image. Cloned it on iMac, then finished installation on iMac
