    I don't see a problem with either of these, so I need to know more about the prior state, what exactly (but concisely) what was done between the working and not working states, and exactly what does and doesn't behave as you expect.

  • MattP94 Level 1 Level 1 (0 points)

    Thanks for the speedy reply. In both cases, I can't select the boot camp partition as a startup disk to boot directly to it. I hadn't tried in a while, but I think what must have caused it was the upgrade to Mountain Lion from Lion. In both cases I haven't touched the partitions themselves since setting up boot camp when I first got them.

     

    The only other thing I can think of that's of note is that in both cases there is VM software that can run the bootcamp within OSX. I have the bootcamp OS shut down in the VM, though, and still can't select it in the Startup Disk control panel. One uses VMWare Fusion. The other uses Parallels.

     

    Let me know if there's any other info I might provide. Sorry if that's too vague. I'll understand if there's nothing to be done.

     

    Thanks again.

    Matt

    Do either of the VM's boot Window successfully? Or do they fail also?

  • MattP94 Level 1 Level 1 (0 points)

    They both work properly.

  • Christopher Murphy Level 3 Level 3 (555 points)

    And what happens if you boot the computers with the option key held down. You should see several icons, is there a Windows option?

  • MattP94 Level 1 Level 1 (0 points)

    Ok, now I feel silly. Tried that on the iMac, and windows was there. It seems like it's coming up normally. I'd assumed there was a problem since the way I'd always gotten it to boot before seemed to be missing. This works fine, so I guess I don't have to worry about that.

     

    Thanks so much, and sorry for wasting your time!

     

    Just as an aside question, could it be that I need to/can download new drivers related to bootcamp, after having done OS upgrades and such?

  • Christopher Murphy Level 3 Level 3 (555 points)

    I found this which seems related once you get to post 6.

    I think the Startup Disk panel expects to use Apple's NTFS (readonly) implementation, in order to locate Windows, and then display it as a boot option. If you're using something other than Apple's implementation, it doesn't get listed (?) for whatever reason. Do you have NTFS-3G installed, or something else that eneables read-write to NTFS?

  • Csound1 Level 8 Level 8 (41,420 points)

    Hi Chris:

     

    FYI, in my experience any 3rd party NTFS utility (Paragon, Tuxera and especially NTFS-3G) will cause this behavior. NTFS-3G is especially buggy with Mountain Lion, just because it is free is not a good reason to use it. In practice the most stable option is Paragon, but the sensible option (as always) is to put Windows on a PC, not a Mac.

  • MattP94 Level 1 Level 1 (0 points)

    Great call again. I have Tuxera NTFS installed so I can read large USB drives on NTFS. Sorry I forgot to mention that initially. Once again you're on top of it!

  • Christopher Murphy Level 3 Level 3 (555 points)

    Curious that the implementation matters. If you're going to pay for read-write support, I'd probably go with Paragon. If you want a free solution, I'd make certain you're not using the positively ancient NTFS-3G build from 2009 (or older) that's floating around on the internet. NTFS-3G is regularly updated, but they don't keep OS X binaries handy. You have to build it yourself using XCode and Macports, which is a bit tedious to learn. But using an old build is asking for trouble.

     

    If you've already paid for Tuxera's version, I'd make sure it's up to date, and I'd file a bug with them (as if they don't already know this) that when using their NTFS-3G software, Windows doesn't show up as an option in the Startup Disk panel.

    I looked in their support forum, and found this:

    It looks like they were saying it's an Apple problem, so there's not much they can do. I'll probably open a ticket with them, just to see, since this was a while ago, but at least I can use the option key, and that's great.

     

    Thanks again for all the help!

    You do realize that the date of that post was 2007, 6 years ago. If they have been blaming Apple for the last 6 years I doubt that anything will change in the next 6 years.

    Go to Terminal, type mount and then post the results here.
