I installed Windows 7 (from MSDNAA) with BootCamp on my MBP (late 2008). After using the BootCamp utility on OSX I restarted the computer and the installation of Win7 began. This first time, there were no partitions to choose as destination. After a restart, I could install Win7 on the Bootcamp partition.

Now every time I try to start Win7, a black screen appears and nothing happens anymore. I tried it with hitting "alt" and choosing windows from the boot menu, I tried rEFIt and choosing windows, I tried selecting windows from the startup disk menu in OSX... I installed Windows at least 5 times, but always get the same problem. The strange thing is: the Windows partition appears in OSX and I can browse the Windows folder, the program files, ...

Any idea what I can try now?

  • Are you running 10.6 and the Boot Camp 3.1 Update?

  • Is it a 32 or a 64bit Windows?

I had weird issues trying to get boot camp to load/run windows. Tried everything and it turned out to be the RAM. I put back in the factory RAM, installed boot camp, then put back my newer RAM after it worked.

It may not be your issue, but thought I would try.


Sounds like a display driver related issue, try booting windows into Safe Mode by pressing the F8 key as soon as Windows starts.


Do you have a CD/DVD in drive when trying to boot to Windows? The BIOS -emulator will try to boot from CD's/DVD's and external USB drives when booting to windows. Just try and remove all external devices (also USB mice etc) and discs and see if it works.

I haven't found a way to alter the boot preferences for the emulated BIOS yet.


It will work in OS Lion. It was reported that the developer build of OS Lion will ONLY work with Windows 7 in Boot Camp.

I know it doesn't solve the issue right now, but it's good to know about.


I have had this multiple times, I had to connect an external display because it was some driver issue with the iMac's display, and update the drivers within windows to resolve.

Good thing I had a projector handy.
