Just switched out my SuperDrive for an SSD on my 2010 MacBook Pro and am running into whale of a time trying to get Windows 7 installed onto the SSD for Boot Camp. Initially tried installing via an external DVD drive connected over USB, but that wouldn't let me boot into Windows 7 setup. Tried setting up a Windows 7 USB stick, and that wouldn't boot either.
I then tried following along here with the basic procedure of tricking VirtualBox into installing Windows 7 to your drive and going from there, but that created a non-bootable Windows partition.
There must be some way to get Windows 7 up and running WITHOUT having to reinstall the SuperDrive. Anyone have any success doing this?
BTW, I'm running 10.7.2, which means rEFIt is out, as it isn't Lion compatible.
