My Macbook Pro has a black screen when running in Bootcamp Windows 7. Since I updated the mac side my windows side now starts up with completely black screen - no prompt, nothing, Cap keys still light up as does mouse and DVD drive seems to run.

Will not show up in safe mode, will not show when started from Windows 7 DVD..................

Are you saying when you start up from the Windows installer DVD and try to repair the Windows installation it doesn't see the Windows install?

Have you booted from the MacOS Installer DVD and used the "Repair Disk" on the Mac side?

i'm serious: try increasing brightness of your screen

next: boot to safe mode, uninstall display adapter drivers from Device Manager and restart and let it reinstall the drivers for you.

And I'm serious.

Try plugging in your MacBook Pro to a power source. I also thought that there is something wrong with the system. Plugged in and was surprised to see the screen came on. Or like what he says, increase the brightness.

This is years old, but was any solution ever found for this? I just had the exact same problem crop up with an early 2013 Macbook Pro and bootcamped Windows 8.1.

EDIT: RESOLVED

For anyone else who finds their way here like I did, this link did it for me: https://forums.geforce.com/default/topic/527599/windows-8-issues-solved-please-r ead-if-you-39-re-having-black-screen-and-or-flickering-/

Specifically, the posts by Dunsany and valkyr did the trick. I booted in safe mode, uninstalled and deleted the Nvidia driver, disabled automatic driver installation, and restarted normally. I then manually downloaded and installed the previous Nvidia driver for my graphics card (which at the time of this writing was 335.23, rather than the latest which was 337.88), and everything is now bueno!

Two hiccoughs along the way: First, when I tried to uninstall the Nvidia driver the first time, when I restarted I got the login screen (which was a good sign), but it quickly went black again. I powered down, restarted in safe mode again, and repeated the uninstallation process, and it worked the second time. Second, when I started the manual install of the 335.23 driver, the computer played a sound similar to the one for disconnecting a USB device, and the screen went black. I'd seen a lot about trying to increase the brightness (though it hadn't worked up to this point; but if you haven't tried it yet, might as well); I tried it, and it worked! So far I'm back up and running. [/fingers crossed]

Hope this helps someone else!
