Deleted bootcamp, and reinstalled windows 8.0 and updated perfect to 8.1 now....who knows. Only thing I can think of that May have caused it, I used winclone to clone and restore my bootcamp drive. Anyone else here with this issue use winclone?
I used Winclone, and had trouble updating. I don't want to reinstall, though. That was the point of Winclone. Hopefully it gets fixed.
I deleted the bootcamp partition, installed windows 8 using windows 8 iso and my original upgrade key (it worked, read on). After it was finished, it deactivated itself and removed the key used. I installed bootcamp 5.0. I upgraded windows 8 to 8 using the same upgrade key, opting to preserve nothing. I had to reinstall bootcamp 5.0. I then upgraded to windows 8.1 successfully, then opted to reinstall bootcamp 5.0 because I have heard of some issues.
Out of curiosity, did you use sysprep before using winclone? I didn't because it was going back on the same computer(resizing bootcamp), thought I read somewhere that doing sysprep changes something in the boot sequence so it recognizes the new hardware, just a thought.
I ain't doing all that lol. I'm not sure it was the fact that you had win7 though. Some people are getting this from a win8 install also. I think it worked because you installed bootcamp 5.
I have bootcamp 4, what does it take to get 5? Do you need to have the latest macos? If so, I give up. Does upgrading boot camp affect your windows install? Do you have to reinstall windows?
I don't know what sys prep is.
My problem was happening with boot camp 5
