Boot Camp: Windows 7 on iMac – Fix Black Screen

Klaus Kjeldsen — Mon, 04 Jan 2010 17:45:12 +0000

Recently I was making a Boot Camp installation of Windows 7 on my iMac, however, it did not go as smoothly as expected. During the installation process the screen went infinitely black, and it was not possible to continue the installation process.

Software versions:

Boot Camp 3.0 (Mac OS X Snow Leopard)
Windows 7

Doing a little search, I found the following solution on how to fix the problem.

Update: Apple has made a support article on the issue: http://support.apple.com/kb/TS3173

Solution (step by step from the beginning):

Run Boot Camp Assistant from Mac OS X Snow Leopard (Applications -> Utilities)
Create a partition for the Windows installation using Boot Camp Assistant
Plugin your install disc and install Windows 7
The system will reboot a couple of times during the installation
The problem: The second time the system reboots, you the see the Windows red-green-blue-yellow animated logo, and then the screen goes black and hangs infinitely.
Press and hold the power button on your iMac until it shuts down.
Start the iMac again holding “alt” key, so you can select and load Max OS X Snow Leopard again.
Run any application that let you work with NTFS partitions (e.g. Paragon NTFS for Mac OS X or MacFuse)
Find the file “C:\WINDOWS\SYSTEM32\DRIVERS\ATIKMDAG.SYS” on your BOOTCAMP partition, and simply delete it.
Restart you iMac, and boot up Windows 7
Now Windows 7 should boot normally
Run update windows utility and install Boot Camp drivers from the Mac OS X install disc

Boot Camp: Create Partition Error – Files cannot be moved

Recently I was about to install a Windows 7 beta using Boot Camp on my iMac, but it did not succeed due to an error. I was setting the Windows partition to 80 GB with plenty of free space available.

Then I got this error, namely “The disk cannot be partitioned because some files cannot be moved”:

But I did not like the idea of formatting my hard drive due to fix the issue, and make Boot Camp work. However, I found an other solution to the problem, namely installing tool to defragment the hard drive. Defragmentation is not something you usually do on a Mac, but here it came in handy. I found these two tool to do the trick:

iDefrag (I used this)

Drive Genius

What the tools basically do, is that they are able to moved the files, which for some reason is blocking the Boot Camp Partitioning.

iPhone Safari Crash Fix

No doubt iPhone’s Safari browser is the best mobile browser, though it seems to have an unfortunate issue, namely, that it tend to periodically crash after a longer time of use with multiple pages. Safari shuts down and returns to the home screen. On the Apple Discussion Forum it seems that more people have experienced the same as I.

I am sure that Apple is aware of the problem, and continuously will provide stability fixes for the iPhone. However, running the latest version, which at this moment is the iPhone 2.1 firmware/software, the iPhone still have stability problems. Hopefully this will change in the next version, the iPhone 2.2 software.

However, it is possible to prevent the iPhone Safari from crashing, though it is not a permanent fix:

You can try to clear the Cache, Cookies and History. To do this, go to Settings > Safari and tap Clear Cache, Clear Cookies and Clear History.
If that is ineffective, try makeing a soft reset of your iPhone by holding down the Sleep and Home buttons until the Apple logo appears (about 8 second). Note that this is also how you power the iPhone off. When the “Slide to power off” slider appears, just keep holding the buttons down and pretty soon you will see the Apple logo appears, indicating that the iPhone is reseting. This can help reset some apps that may be running in the background. Importantly you will not lose any data.
