Mac Book Pro - Dual Boot

933 Views
Last Modified: 2014-01-15
I have a MacBook pro 13" Model which has come originally with 500gb Hard disk . I have configured bootcamp along with OS X  & installed  Windows 7.

Win 7 is selected as boot partition.

i have removed the ODD added another SSD and formatted it as 'Mac OS Extended (Journaled).

Now, if the SSD remains connected then Win 7 does not get loaded, only black screen appears and cursor keeps on blinking.

As soon as i remove the ssd connection Win7 boots properly.

Is there any way both of these can co-exists.

BC is selected as 1st boot option  & even if i try to load Windows option manually by pressing Option button the black screen with cursor blinking appears all the time.

No way win 7 loads till i disconnect the addtional drive...

OK, a couple of options.  I've done some research on this and it appears that you're not alone. Make OS X the startup volume and see if you experience the same thing. If you do, then it's either hardware or that's just the way it is -which I doubt since I do something similar without problems. I suspect that OS X will boot just fine. If OS X has the same problem, try resetting the SMC: http://support.apple.com/kb/ht3964

If OS X boots fine with the external drive attached, then the only other thing that I found for a Windows BC boot with this issue was to go into the Network connections center and, if you have an IEEE BW connection, disable it. Now this last suggestion was for an external drive connected via Firewire, so it may not even be an issue in your situation.

Like I said in my first post, I had a user with a straight Windows laptop who had a device connected via USB that wasn't even a storage item and Windows 7 would NOT boot until I disconnected it...it may just be a Windows thing.

As you rightly say OS X boots fine & there is no IEEE connection also.
