Retina 5K - AMD Boot Camp Driver failure

yes how to see the log file ?

The log is your Event Viewer. I am referring to something similar to https://msdn.microsoft.com/en-us/windows-drivers/develop/debugging_a_driver .

Still no luck - error 43.

I've looked at this thread from beginning to end and also read other threads from all over the internet from people who had this issue. Oddly, some individuals had better luck starting over.

I actually updated to Mavericks this morning in the hopes there was a 6.0 Mavericks windows driver update but I figured that was a long shot.

Against my better judgement I'm actually going to start from scratch this time rather than beating my head against a wall trying to rescue the same windows installation and figure just starting from zero will be the best possibility instead of wondering if I did every step in this thread in the right order.

More once I actually finish the reinstall.

If you can re-install, and keep track of the steps, it may be easier to find a resolution. The 5k/4k iMacs have caused as much grief, if not more, as the 2011 AMD GPU MBPs.

Yep. I plan on publishing a blog entry on this - I think the problem stemmed from first installing from a Windows 7 64-bit ISO, then upgrading to 8.1 then upgrading yet again to 10. That process was full of issues as well. If I start at 8.1 (I have the actual disc) I should be able to get that going to start with and then document each step if the issue happens again. I figure there's a good chance it could. Stand by and thanks for the assist.

Once you install W10 and activate it, you can directly install W10, since your Mac is registered with Microsoft.

Hi guys

Take some news about this fu... Amd drivers. Still not works for me. I ve contacted apple support. The reply is a link to apple support 🙂

Waiting for a new drivers

good luck

I ran into a bigger problem with my machine that necessitated not only rebuilding boot camp but rebuilding the entire machine altogether from backup.

The reason this happened is I was attempting to install Windows 8.1 (since I had the disc) and then update from Windows 10 from there. I guess I wasn't certain how getting Windows 10 on the machine without any previous version.

The problem: when you install Windows 8.1 it can't be installed on the boot camp partition. I now understand the discs are GPT, but Windows thinks they are MBR, you can't use anything from Microsoft to change the partitions on the discs but I wasn't aware of that at the time so I ended up inadvertently nuking my fusion drive partition when I was just trying to give Windows 8 the proper format for installation and ended up having to rebuild my fusion drive and my Mac OS from scratch then restore from backup. Ow.

I have yet to reinstall boot camp - I'm running into some other issues (machine decides to reboot by itself since I rebuilt it in some cases). I've heard LaCie USB3 drives have caused reboot issues when running some applications.

Do the reboot issues disappear if the LaCie USB3 is disconnected?

HI

Maybe this is the reason why the device is stopped, got this when right clicked on card status :

PCI\VEN_1002&DEV_6819&SUBSYS_014E106B&REV_00

That’s ok ?? (REV 00 ?)

Error code : 0000002B

For info there is new drivers this morning "crimson" 1.6. Officially there not made for bootcamp.. Whith so much hope I've tried them. But nothing change

@sunmetis:

I got exactly the same problem, i tried out everything.

THE ONLY SOLUTION WAS.

Get a Old Windows 8 ISO not windows 8.1 the WINDOWS 8 classic one...

Your graphic card will be regoniced as a AMD RADEON 7800 Series and it works fine. Don't update anything on windows 8. If you do, your graphic card won't work anymore.

Maybe there would be another solution which is to sign a custom made driver by yourself.

Thx

This is what I did one week ago (install win8) and how I crash partition. **** was so hard to make the fusion drive ok... Now osx and Win 10 are fine (exept for the radeon). I don't want delete. 2500 Euros for one Imac and bootcamp. I just want the driver. I don't understand why apple didn't test it before on new IMac.

We are a lot with this error.

arfff

We should search.. why its works when you installed win 8 first

Hi

Asked to a sell about this problem he told me :

"yes, many customers are in this situation"

This is so general. Any news about the drivers ??

Thx

News about the drivers? It works?

no one does not work?
