Thank you

If you have not made a back-up of your Mac OS before hand, I think you will have to start all over again.

    That doesn't sound good. It sounds like the power outage might have corrupted the partition for OS X. I would suggest booting from the Install DVD that came with your Mac while holding down the C key. Once you have selected the language start up Disk Utility from the pull down menu and repair the disk. Once you have done that then repair permissions also.

    It sounds like you destroyed your boot partition and the recovery partition.  Depending on it's age, your MacBook Air might be able to do a net boot.  Plug and ethernet connection into it and attempt to boot.  If it has the right firmware, it will find a net boot configuration on the net and boot that.  Then it will give you a Recovery Partition like display and allow you to reinstall the OS X version that came with it.... assuming that it was Lion or ML.  If your computer came with Snow Leopard, then even the net boot won't work. 
    At that point you need a bootable USB Key, or an external DVD drive AND a Snow Leopard installation DVD. 
    An Apple Store, if there is one nearby, MAY be able to get you going again.  However, whatever is on the SSD now will be toast too.

  • Get back to Mac from Win 7

    I'm not sure how I managed to do this but...
    I deleted my VmareFusion partition with win7, and vmware fusion.
    Then I upgraded to Lion.
    Then...
    I created a new partition using Bootcamp assistant and then re-installed Win7.
    At some point, when I was away from the computer, it turned off.
    I restarted it and went into system preferences and set it to boot to the new partition and then rebooted it,
    and it completed the Win7 install.
    But now I cannot get back to Mac. It only boots up to win7.
    I am working away from home and do not have my snow leopard startup disk..
    How can I get back to Mac, and properly set it up to ask me which partition to boot from upon startup?
    Thanks.

    Boot your Mac while holding down the Alt/Option-key until the Boot Selection screen is shown.
    Choose your OSX to boot from.
    Once in OSX go to System Preferences - Startup Volume and set your OSX to be the default.

  • AMD Crossfire, Boot Camp, and the new Mac Pro Issue

    Hello, all.
    I have a new Mac Pro (Late 2013) with 6 cores, 32 GB RAM, and dual D700 AMD graphics cards.  I'm using an older 30 inch Apple Cinema Display (with the dual link DVI adapter).  I've successfully installed Windows 8.1 under Boot Camp.  Here's my problem...
    I understand that for the new Mac Pro under Boot Camp enables AMD CrossfireX by default from multiple sources online.  However, it's disabled on mine, and every time I try to enable it (and hit "Apply" in the AMD Control Center), it disables again.
    Is Crossfire only available for use with a Thunderbolt Display attached?  Could that be the problem?  Or is the AMD Control Panel lying to me?
    Now, games in Windows are still running well... But I'd like to take full advantage of the dual graphics cards in the new Mac Pro with Crossfire.  Any help is greatly appreciated, thanks!

    Fixed it!
    So, not only would Crossfire not enable under Windows 8.1 on my Mac Pro in Boot Camp... But Windows started crashing massively.  I was about to wipe Boot Camp entirely and try a clean install (even though the only three things I'd installed were Windows itself using Apple's exact instructions, Steam, and Skyrim), but decided in a last ditch effort to try disconnecting and reconnecting peripherals.
    Turns out the culprit was my Belkin Thunderbolt Express Dock.
    Disconnecting the Belkin Thunderbolt dock not only stopped Windows from crashing, but now I can enable Crossfire, as well!
    Now, this is especially strange since I have read elsewhere that people have no problems using the Belkin dock under Boot Camp with other Macs... This issue is probably isolated to using it in Boot Camp with the new Mac Pro.  But disconnecting the dock from my Mac Pro has solved not just one but all of my Boot Camp issues.  (Of course, using the Belkin dock under OSX on my Mac Pro is no problem.)
    Long story short, if you have a new Mac Pro and plan on using Windows 8.1 under Boot Camp, don't have the Belkin Thunderbolt Express Dock attached.
    I'm going to contact Belkin and tell them what I've discovered.
    Hope that helps y'all.

  • Hi guys i used boot camp and turned my mac into windows and i wanted to play a pc game on the windows and i cant find a proper program to actually setup the game someone help me please

    hi guys i used boot camp and turned my mac into windows and i wanted to play a pc game called guild wars 2 and i cant find a proper program to actually setup the game

    Only if you decide to share with us your particular situation. Guild Wars should install and run like any other Game. Other than the Game Installer, Games don't need some other installer to make them work. Only someone who reads the instructions for the proper installation.

  • I need help with boot camp. "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."

    This message appears every time I try to partition my disk:
    "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
    I verified my Macintosh HD disk on Disk utility and then tried to repair it, but I am unable to click the repair button.
    It says it's not available because the startup disk is selected.
    I don't know what to do or how to go about both these problems.
    Please, any suggestions?

  • Boot camp probl"back up disk and use disk util. to reform as single MAC OS.

    The disk cannot be partitioned because some files cannot be moved.
    Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.
    I am trying to install win 7 32 bit but before i partition my mac osx an error message pops up with the above wording...I went to disk utility and it is already a single mac osx (journaled). any help would be great and much appreciated..thank you for viewing.

    The error message must be the title of 100s of threads.
    Do you know how to backup?
    It can't move files, some are fixed, the free space has to also be unfragmented contiguous chunk at the end of the drive.
    Disk Utility Restore tab (and Help menu).
    and of course external backup drive. And backup is step #1. There is a PDF you can save or print from the Boot Camp Assistant.
    If you only have TimeMachine for backup you might want to install OS X anyway on a small 30GB partition (shrink partition size) or use your OS X DVD.
    From OS X DVD go to Utility and then Disk Utility. Restore to another drive and that should be then bootable.
    Or pick up SuperDuper or Carbon Copy to clone-backup and use one of those.
    iDefrag $$ may be able to optimize the free space.
    But it is wiser to first insure any data and files are backed up before changing or installing another OS, and before changing partitions around.

  • After I enter my password in my Mac mini, my screen turns black. I know it is there, ( i can hear the assistant), but I cannot see anything. i went to Genius and they said hold Control, Option, P, R on the re-boot to get back to factory settings...

    I went to the Genius bar and they told me to Control, Option, P, R on a reboot to restore the settings, but with a wireless KeyBoard it does not work. I installed my standard PC keyboard, but am not sure what keys renase the display back to factory settings.

    Hello Dominique,
    Generally on a PC Keyboard...
    Windows key = Command key on Mac
    alt key = Option key on Mac
    PRAM reset, CMD+Option+p+r...
    http://docs.info.apple.com/article.html?artnum=2238
    With PC KB... Windows+alt+p+r
    But try holding the Shift key down at boot to get into Safe Mode, see if the Display settings need adjusting.

  • Boot Camp 3.0 recognises Mac HFS drives but does not list all folders

    Hi
    I have just done a clean install of Boot Camp/Windows XP using the Boot Camp 3.0 drivers that come with Snow Leopard, and was pleased to find native support for Mac Drives (HFSJ). Whilst all of the Mac drives in my Mac Pro are recognised and can be opened and explored in Windows explorer, a number of folders in one of the drives didn't show up. I could access them by typing the exact path in windows explorer, but when using the mouse to open the drive a number of folders could not be found. Furthermore, windows applications, such as media libraries, would not pick up any files in the folders that couldn't be seen in explorer.
    I went back to OSX to check that all of the folders were indeed present and they were. So in the end I reverted to using my Macdrive software again and all of the folders showed up again and worked as expected. So, it may be that the new bootcamp drivers are not all they are cracked up to be.
    Anyone else experienced similar issues, or got any clues as to what I might need to get this working right?
    Thanks
    Nick

    I am having that issue, but haven't worried about it since I've only booted to windows 2 times since the upgrade. Both times I've experienced a much more aggravating problem. Both times in order to reboot to OSX I have to use the install disc to repair the OSX drive because something renames it to "disk1s2" plus some counts are invalid. I use Macdrive, but since SL the mac volumes appear just as any other drive icon. Using Parallels or Fusion works as it always has, automatically shutting of Macdrive which leads me to think that Macdrive may be the culprit. Gonna try disabling it completely while running virtual and see if that makes it work. If not it'll just be another aspect of my Mac that Apple updates have made useless.

  • Can't get back to Mac OS X after windows 7 install

    I have a Macbook (aluminum one, not a pro)with leopard OS X and have gone through the process of creating a 60gig partition and installing windows 7 32bit ultimate edition on it using boot camp. After the installation process and several restarts, it seems windows 7 works great... The problem is I have no idea how to get back to OS X.
    When I restart the computer it gives a gray screen for a moment then a black screen with a white blinking cursor, it flashes to the typical windows OS selection screen for about 1.5 seconds then boots up in windows 7. I have spammed the up arrow key to make sure that I am able to interact with the DOS OS selection screen and windows 7 is the only one shown.
    I am completely lost as to what to do about this. My Leopard OS disc is long gone, I have an .iso of it saved on my Mac partition but I don't know how to access that either.
    If anybody could help me out I would be ever grateful. Thanks in advance.

    Windows 7 has a hidden task bar at the bottom of the screen. It really isn't apparent especially if you have not used Win 7. This is not the power looking icon in the lower left, move the cursor to the lower right side and the task bar should appear.
    Then, as with other windows versions, there should be a shortcut that allow you to access Bootcamp. Once in the bootcamp window you can select to reboot back to the Mac OS.

    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
    1. Install the Apple Boot Camp software.  Purchase Windows XP w/Service Pak2, Vista, or Windows 7.  Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows.  Boot Camp enables you to boot the computer into OS X or Windows.
    2. Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7.  Parallels is software virtualization that enables running Windows concurrently with OS X.
    3. VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7.  VM Fusion is software virtualization that enables running Windows concurrently with OS X.
    4. CrossOver which enables running many Windows applications without having to install Windows.  The Windows applications can run concurrently with OS X.
    5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris.  It is not as fully developed for the Mac as Parallels and VM Fusion.
    Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc.  There are performance differences between dual-boot systems and virtualization.  The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
    You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.
