Boot Camp won't start in Windows 8

Hi All,

I got the new MacBook Pro with Retina Display this week and I installed Windows 8 Release Preview with Boot Camp. The reason I used Windows 8 is because the Retina Display is not supported in Windows 7 yet.

The dual boot and drivers are all fine. The only problem is that the keyboard doesn't work as how normal windows keyboard... For instance, the function keys only work when fn is pressed, or they are basically doing special tasks like changing the brightness, etc.

I know this is the default behavior in Mac OS and you can set it through keyboard settings. I also know that Boot Camp in Windows should be able to deal with that too. However, when I try to launch Boot Camp in Windows 8, it always give me me this error:

---------------------------

Boot Camp

---------------------------

An error occurred while trying to access the startup disk settings.

You may not have privileges to change the startup disk. Make sure you have administrative privileges and try again.

---------------------------

I used to use the 27 inch apple display with Windows 7 before, so I know this is realted to the fact that the system is using AHCI driver instead of ATA driver for the harddisk. Seems like with Boot Camp 4.0 and Windows 8 Release Preview, the system natively boots into and supports AHCI mode. I verified that in the device manager in Windows 8.

So, how can I use boot camp in Windows 8 with AHCI driver? If I cannot do that, is it possible to get back to ATA mode? Or, is it possible to change the behavior of the keyboard without using boot camp? (Of course I can use the default driver for the keyboard I guess, which basically make Fn doesn't work and make "delete" doesn't work since delete = fn + backspace).

If none of them are possible, when will Apple update boot camp to run with Windows 8? Or, when will Apple release the retina graphics driver for windows 7?

Thanks

MacBook Pro (Retina, Mid 2012), Mac OS X (10.7.4), Windows 8 Preview Release

There are bugs with using Apple drivers and you can bet that no one knows when Apple might release something, they tried releasing Boot Camp 3.0 before Windows 7 RTM though at the end of RC, rushed to say the least to put it on snow leopard DVDs months before 7 was ready, resulting in buggy drivers.

Luckily Boot Camp Assistant works. Bad news: they could tie Windows 8 drivers and support to Mountain Lion. Some Macs would fully support 8 but not 10.8. Posting the drivers seems to be ignored // out of the question and has never been done. Nor does Apple's software udpate in Windows seem to be used for Boot Camp related drivers.

There is another solution that Shampu mentioned. It takes a bit of technical know-how. This solution doesn't require switching your account status and permanently fixes the problem.

1. Download and Install the windows 8 SDK - http://msdn.microsoft.com/en-us/windows/desktop/hh852363.aspx
2. Navigate to C:\Program Files (x86)\Windows Kits\8.0\bin\x64 (or x86 at the end if you're on a 32 bit version)
3. Copy C:\Windows\System32\AppleControlPanel.exe to this folder
4. Open Command Prompt and use mt.exe to extract the manifest to this folder using the following command:

mt.exe -inputresource:AppleControlPanel.exe -out:extracted.manifest

5. Edit this file in notepad. On the 6th line replace level="highestAvailable" with level="asInvoker". Be careful not to change anything else here.
6. Place the modified manifest back into control panel using mt with the following command:

mt.exe -outputresource:AppleControlPanel.exe -manifest extracted.manifest

7. Copy and Replace AppleControlPanel.exe back to C:\Windows\System32\AppleControlPanel.exe

This will fix your boot camp control panel problem. (If it doesn't you've set Bootcamp.exe to run as administrator, and you need to lower its permissions back to normal. I had to change the aforementioned setting, use task manager to end Bootcamp.exe, and then restart it before it worked. (This program is found in C:\Program Files\Boot Camp))

Good luck guys. If you need additional help let me know.

I'm wondering if this boot camp startup control panel problem is related to the sequence of setting up the AHCI drivers in relation to the boot camp drivers.

Specifically, I installed Windows, then boot camp drivers then later configured the system to use the AHCI drivers and had this problem with the boot camp start up disk control panel.

I'm wondering if the sequence was reversed, that is, install Windows, configure and install the AHCI drivers and THEN, install boot camp drivers in Windows, will this problem still plague the system?

You need to reduce the UAC settings-

Open the Control Panel (icons view), and click on the User Accounts icon.

Click on the Change User Account Control settings link. (see screenshot below)

Move the slider up or down to the setting for how you want to be notified by UAC, and click on OK. (see screenshots below)

Push it all the way down,

How UAC works in Windows 8 is, all apps run as a standard user with standard privileges. When an app needs elevated permissions, it triggers that dialog which dims our desktop. However, some apps like BootCamp Control Panel just aren't designed to work with UAC, and end up saying you don't have privileges. When you put the UAC settings to the lowest, all apps still work as a standard user with standard privileges, but Windows silently grants Admin privileges to apps that ask for it.

Hope this helps!!!

Thanks guys for helping find a solution.

Another way:

1. Create the standard user

2. Go to c:\windows\system32 and find the AppleControlPanel.exe

3. Hold down "Shift" and Right-Click the AppleControlPanel.exe

4. From the context menu choose "Run as different user."

5. Type in your new standard user and password and it invokes the RunAs command as that user which we all know works.

6. Disable the standard user if you do not get into the program often. Doing it this way also prevents extra profiles from being created.

You can also make a quick shortcut on your desktop. Here is a quick youtube video I made of the process and why this happens..

Are you referring to BC Assistant or BC drivers?

On a 13" mid-2012 MBP, my BCA is v 5.1.3 (build 498) on Yosemite 10.10.2. The correct BC drivers (not the same as BCA version) can be found at Boot Camp: System requirements for Microsoft Windows operating systems - Apple Support.
