"No bootable disk" when installing Windows 7 on Macbook Pro (HDD caddy)
Here's the deal.
I have a 2011 Macbook Pro (8,1) that I bought a HDD caddy for. It's beautiful.
I replaced the superdrive with a 1tb hard drive and it's wonderful. I want to install Windows 7 via bootcamp on it. I go through the steps (create install usb, download extra files, partition the drive) and once it restarts I get the following error:
I press keys, reinsert the usb stick repeatably, and finally hold down the power button to restart. After holding down option to bring up the boot menu, this is what I get:
Where did my other disks go?! I boot normally and check Disk Utility and, look at that, there they all are!
I've gone through variations of this for 3 days now. Please help!
MacBook Pro, OS X Mountain Lion (10.8.1), 2.2 GHz Intel Core i7
