Hello, I installed SSD in place of optical drive, bought enclosure from OWC and using it as external drive. Now I am trying to install Win 7 via bootcamp, it attempts to boot from the cd, and goes to a black screen with the blinking underscore cursor, but still can’t boot. I tried with refit tool, it didn't work either. Anyone has this problem? How do i resolve it? Thanks, Edit: BTW, I tried with both Official Win 7 Ultimate DVD and the win7 pro image burned to DVD which was downloaded from MSDN.
