Yosemite Boot Camp Drivers

Hi,

Thanks in advance for any help I receive. After upgrading to Yosemite, like many, windows 8 was having a problem loading. As soon as the 8 desktop would appear, the screen would go blue and Windows would shut down. I erased the partition and started over. Here is the procedure I used:

1) Launch Boot Camp assistant

2) Download latest drivers to flash drive

3) Boot Camp assistant partitions the drive ( 400 GB Windows partition)

4) Boot Camp restarts and installs Windows (8.0)

5) Windows asks me to select a drive to install windows.

6) I select the BootCamp drive, but I have to use the format tool on the installation page to format it to NFTS (otherwise I cannot install windows.

7) Windows ask for key-key accepted

8) Installation runs fine-Windows asks for all the setup information

9) Desktop appears

10) Boot Camp support drivers program runs automatically and installs drivers-computer restarts fine.

11) Problem-once the desktop appears, as soon as I start to do anything, the blue screen appears that says windows had a problem-

12) no amount of windows self repair works short of taking it back to a point before installing Boot Camp support drivers

Either I am doing something wrong or the problem is the Boot Camp drivers need to be upgraded by Apple.

The error I see on the screen says something about "security check on Ktext" or something close to that.

Any ideas?

All the best,

Ciro

Was step 2 a manual step or was it done by BCA? What is the error message in 11?

Hi Loner T,

Thanks for the reply. Firs the links Kappy provided are the procedure I followed. To answer your questions, BCA downloaded the the drivers. I assumed that it downloaded the 5.1.5621, which seems to be the correct drivers for my machine, a Mac Pro mid 2010. The 5.1.5640 drivers are for 2013 macs. I tried downloading the 5.1.5621 software manually and running it once Windows loaded, but I got the same problem.

The error message that appears in step 11 is "kernal_security_check_failure" This seems like it might be related to Yosemite. Doesn't Yosemite now have some security feature related to ktext files? I am getting this from Trim enabler.

Thanks

Ciro

Yes, the Yosemite security feature is described at http://www.cindori.org/trim-enabler-and-yosemite/. But you are getting it in Windows then Yosemite has no relationship to it. Please see http://msdn.microsoft.com/en-us/library/windows/hardware/jj569891(v=vs.85).aspx

5.1.5621 are the correct drivers. This is usually related to some device driver. Was Mavericks/BC working as expected?

OK, I see. It was just a similarity in naming. I checked the windows dev site and all the items listed in for the error. Unfortunately, the blue screen provides no more information than the name. Everything was working under Mavericks. The problem started after upgrading to Yosemite. I just tried a bunch of recovery restarts and the problem got worse. I am going to wipe the partition and start again. Any advice? I am installing windows on a drive in bay 0 that also has a clone of my hard drive. I run my system from and SSD drive on an Apricorn card. I am not trying to install windows in the SSD, but could the card be interferring with the install?

On a MacPro, if you want to install Windows on a multi-drive system, it is better to remove all drives other than the designated Windows drive and re-install them after Windows completes. Except the new 2013 MacPro, the older MPs have Optical Drives, so the Windows installer would run from a Windows Installation DVD.
