Reposting from iMac community:


Hey, so I have a Mid-2011 iMac, 27'' high-end. I've got Windows 7 boot camped on 200 GB of the HDD, and for the past month it's been smooth sailing, switching between the two. Now today, for some reason, it decides not to boot.

Here's exactly what happed:

Played Minecraft for six hours in OS X, hosting a server

Closed down every program

Opened Settings > Startup Disk

Chose "Boot in Windows"

Computer shuts down, turns back on, and now it's stuck on the black screen right before it says "Starting Windows".

I've tried every combination of keys, also with a USB keyboard instead of the Bluetooth one, but I'm under the impression it's not even registering that the keyboard is there. All I can do it turn it off, then turn it back on. It makes the sound when it turns on, then cuts straight to black, no gray screen.

Any ideas on what to do here? Kinda need it to work for school.

    Microsoft Windows insalling an update.


    The first thing anyone should do, well first is to make a backup system restore image, so 2ND thing, boot from Windows DVD and rollback to last good boot point.


    Probably the same as the original iMac 27" black screen issue.

    But that is for install Windows not after.

    Click and hold mouse down during startup to pause and open the optical drive door.
