I have a 2012 Macbook Pro. I took out the optical and installed the following set up: 128 GB SSD in hard drive slot - Single Partition - Format: Mac OS Extended (Journaled) - Mountain Lion Install + Applications and select User folder 750 GB OEM HHD in optibay enclosure - Partition 1 - Format: Mac OS Extended (Journaled, Encrypted) - User Data - Partition 2 - Format: NTFS - Windows 7 Enterprise Install You probably already know that it is difficult to get Bootcamp and Windows 7 to install on a hard drive in the optibay but I got it to work by using a external hardrive . I opened up the Macbook and disconnected the SSD from the motherboard. I used the OS X install on the external USB to boot and run boot camp. Boot camp created a install usb stick from an ISO of Windows 7 Enterprise (to which I have a legal license) and create a partition for Windows. I went through the reboot (be careful because before you restart you have to unplug the USB hard drive with OS X) and installed Windows 7. Everything worked beautifully and the installed great. I installed programs and rebooted several times with no problems but when I plug the SSD in and try to boot into Windows 7, I get a black screen with a blinking cursor. If I unplug the SSD, I can get Windows to boot just fine. Is there anything I can do to get both OS X booting from the SSD and Windows from the HHD. Thanks for the suggestions.
