Hi folks, I'm running a 15" MBP Mid 2009.

  • 2.8 Core 2 Duo
  • 8 GB RAM
  • Nvidia GeForce 9400M 256 Mb
  • OSX 10.8.5


Just this weekend I purchased Mountain Lion and decided to start completely fresh. Used the AppStore download to create a USB boot disk. Removed all existing partitions (Read: used disk utility to erase and format as MacOS Extended (journaled)). Installed the fresh copy of OSX to this new partition. Once in the OS I configured my settings, installed iLife and Office and updated all software. All is well with OSX, now it's time for Windows 7.


I run bootcamp assistant. I resize the partitions such that Windows gets 250GB and MacOS gets 500GB. It prepares a usb stick with support files on it then makes sure it's not bootable. I insert my Windows 7 Ultimate disk and get ready to reboot.


Once I reboot I can hear the disk churning and working but the screen is completely black. Tried closing and opening the lid and nothing. Eventually my only choice is to hold the power button for 5 seconds. I use the option key to boot back into OSX fine and everything is as expected there.


For reference the disk i am using is the same exact disk I had used previously to install Windows to this very machine. I have also tested it on other PC's to verify it is bootable so that may rule out a lot of the common suggestions. I also re-burned the same iso at a slower speed and I'm getting the same results with both disks.


What I've found on the web and/or tried:

http://support.apple.com/kb/TS3173 - Seems to be related to the iMac of the same year. I'm hesitant to install iMac drivers on a MBP. However I have a feeling that the issue might be related.


http://support.apple.com/kb/TS2600 - Resetting PRAM and SMC did not resolve the issue. Still unable to boot to the Windows 7 Boot disk


http://support.apple.com/kb/TS4536 - This described a different problem as I do not have the blinking cursor, however I did try removing the USB drive that OSX prepares but no luck there either.


http://apple.stackexchange.com/questions/12275/black-screen-when-installing-boot -camp - References the first 2 KBs I found but the interesting suggestion here was to try a second monitor. The best I had available was a mini display port to VGA and using a VGA-to-DVI cable to talk to my monitor (which has no VGA port). No luck there. tried plugging/unplugging the adapter a few times.


http://forums.macrumors.com/showthread.php?t=1229631 - On this thread, Post #18 suggests that the new EFI does not allow booting off CD and apparently the USB stick needs to be bootable to make changes to the EFI to allow it to boot from CD. I'm not sure about the validity of this claim but I did download the BootCamp 4.0.4033 for the MBP mid 2009 to try to make a bootable USB - This is on my list of 'to try' items


I knew I was hitting a point where pretty soon I won't be able to self-prescribe the solution so I came to the community for answers.
