How to Reinstall  MacOSX over windows 7?

After installing Bootcamp on an iMac I later upgraded to windows 7 but (foolishly!) managed to install this on top of MacOSX so I can no longer boot into MacOSX. Does anyone know how I can reinstall MacOSX again?

From backups.
From Lion Recovery Mode on new Macs.
From OS X DVD from older systems

  • How to reinstall itunes without windows error 2

    how can i reinstall itunes without "windows error 2"

    Ah iTunes, how you make me lose my hair.....
    I got it working, but not before it imported all of the wrong stuff.  I set the Media Folder to precisely what I wanted it to import (all of my daughter's Top 40 songs), and then found the Music option "Add MP3 and AAC Files from your folder".  That seemed to be the correct option, so I clicked it.  Unfortunately, it didn't just stick to my folder, but went off on its merry way adding any song from any folder.  It dumped hundreds of ACDC and Aerosmith songs into iTunes (neither band is particularly stingy with F-bombs on live albums) into my daughter's list of teeny bopper titles.  When I tried to remove them from the iTunes library, it put up a scary warning that if I removed those songs it would delete them from every iDevice within a 5KM radius.
    There doesn't seem to be any way within iTunes of removing all songs from a particular folder or hard drive directory, which would have been nice.  In fact, I can't figure out how to show the filename anywhere within iTunes (isn't that a bit odd?).  So I manually removed the 2K songs it had imported, which took a good hour.  Then I found the File - Add Folder to Library option, and that one allowed me to select the folder I wanted to import.  I hate to say it, Apple makes great hardware products, but iTunes seems to come from an entirely different planet.

  • How do reinstall Lion over SL?

    I am using an imac at our school site that came with Lion pre-installed on the machine. The district decided that they didn't want to deal with possible incompatibilities so they just installed Snow Leopard over every new incoming mac (a choice they have since reversed). My question is, how do I re-install Lionm on this machine. THe license for Lion came with the machine so I

    So what you are sayiong is the computer you are using came with Lion pre-installed and you or someone else erased Lion and installed Snow Leopard.
    Is that correct?
    If so does the recovery HD partition still exist on the hard drive?
    If it does or doesn't boot the computer while holding down the Command and the r keys (Command+r) and that will do one of 2 things.
    1) Boot off the recovery HD partition on the internal hard drive.
    2) Connect you to the Apple servers to boot the computer over the internet. You must have the computer connect to the intenet to do this.
    In either case you will then be able to reinstall Lion.
    Good Luck.

  • How do you reinstall 64-bit Windows 7 in UEFI mode?

    I have a PC with a single hard disk and, a while ago now, I installed 64-bit Windows 7 on it in UEFI mode. 
    The disk has two primary partitions: a C: partition which contains my Windows 7 system and other installed software such as Office, and a D: partition which contains only personal data. 
    (In other words, I don’t have a multi- or dual-boot system.)  
    I now wish to reinstall 64-bit Windows 7 into the same C: partition, again in UEFI mode.
    There is a procedure for reinstalling Windows 7 documented on the following MS Web page:
    http://windows.microsoft.com/en-us/windows/installing-reinstalling-windows#1TC=windows-7
    in the section entitled “Using the Custom installation option without formatting the hard disk”.
    The following YouTube video demonstrates this procedure:
    http://www.youtube.com/watch?v=fr_s29MWOA0
    and it looks relatively straightforward. 
    Essentially, the re-installation starts by inserting the installation DVD into the optical disk drive and running setup.exe while still logged on to Windows 7 with an administrator user ID. 
    At the screen entitled “Where do you want to install Windows?”, both the System Reserved partition (the example in the video is a legacy BIOS installation) and the C: primary partition are visible. 
    On that screen, you simply select the C: primary partition and click
    Next, and Windows 7 is effectively reinstalled over Windows 7. 
    Any personal data in the C: partition is preserved in a folder called Windows.old.
    The big question is, does this procedure work for a UEFI installation? 
    The documentation does not state that it works only for a legacy BIOS installation. 
    If I were to follow the procedure, when I reach the screen entitled “Where do you want to install Windows?”, I would expect to see the EFI System Partition (ESP), the Microsoft Reserved Partition (MSR), my C: primary partition and my D: primary partition. 
    Can I simply select the C: primary partition and click Next to start the (re-)installation?
    It appears that nowhere in the procedure do you specify what mode of installation (legacy BIOS or UEFI) is required. 
    Does the installation setup simply use the same mode as that of the existing installation?
    Does anyone have any experience of reinstalling Windows 7 in UEFI mode, using this procedure or any other method?

    Hi,
    It depends. Do you have Windows 7 DVD? Does your computer have a Boot from EFI Drive option?
    Windows 7 DVD can boot in either BIOS mode or UEFI mode. Different UEFI firmware implementations support different methods for handling the installation operation. The processes for booting the computer into UEFI mode for the Windows product DVD are
    the same. If you can find a boot from EFI Drive option, please perform the suggestions as i referred to.
    If you cannot find any boot option, perform the steps below:
    Use Device Manager's Firmware option and select Boot from EFI Internal Shell.
    Use the EFI internal shell, as follows:
    Start the EFI internal shell from the EFI boot menu and select the drive with the Windows product DVD. The following example assumes that the drive is Fs0:
    Shell> Fs0:
    Start the EFI boot application. For example, on an x64 system, run the following command:
    fs0:> \EFI\BOOT\BOOTX64.EFI
    After the application starts, you may be immediately prompted to press a key to boot from the drive to continue. Press a key to continue booting from the installation media.

  • How to reinstall PDF Printer in Print & Scan window on OSX 10.8.2

    Hello,
    I was having issues where PDF's were not saving when I was printing them, so I thought that if I deleted the PDF printer from my list of printers and reinstalled it, my problem would be solved.  Now I can't figure out how to reinstall (add) the PDF printer back into this window.  I have uninstalled and reinstalled Acrobat, and I have been searching the web for about an hour.
    I am running OSX 10.8.2
    I have Adobe Creative Cloud installed
    I am on an iMac 3.4 Ghz Intel Core i7

  • How to reinstall windows 8 on bootcamp

    how to reinstall windows 8 on bootcamp macbook pro, without losing anything on OS (Apple) side

    Start Bootcamp Assistant then select the option to remove Windows and return your drive to a single partition. Once Windows is removed start Bootcamp Assistant again and select the option to install Windows. Follow the Bootcamp instructions for installing Windows.
    This process will not cause lose of OSx data or applications if done correctly. But as allways, create a good backup of your data because things sometimes go wrong or instructions are not followed causing data lose.

  • Windows 7 home premium reinstall over windows 8

    Can I reinstall windows 7 home premium over windows 8?  I made the mistake of installing windows 8 as soon as it came out and I dislike it very much!  I want my 7 back!!!!!!!!!!!!!

    I don't know where you have bought this notebook but I know, for instance, that many people who sold notebooks on the eBay write in description that notebook has preinstalled other Windows version but notebook has valid product key that can be used for any Windows activation.
    Fact is that this information is wrong.
    Every Toshiba notebook offered with preinstalled OS has Microsoft sticker at the bottom side but product key on it belongs to original version delivered with the notebook. With other words: this product key s useless.
    If I understand you right you have non-activated OS version preinstalled on this machine but also you don't have original recovery installation disc.
    Now you have two options:
    1/ To order original recovery disc (link posted by Tonny)
    2/ To install own OS version using Microsoft installation disc and pay for valid licence.
    In my opinion option to buy recovery disc is best for you. Using this disc in 2 hours you will have perfectly installed OS that will be activated and you will not have any problems anymore.
    After clean OS installation all you must do is to optimize it and configure for usage. Thats all.

  • How to reinstall Windows 8 on Yoga 13 with damaged Recovery Image?

    I changed the partitions on my Yoga 13. Now it is not possible to refresh, reinstall or perform an advance start-up, as it looks like there is no recovery image anymore. The systems is currently very messy and needs a reinstall.
    Can someone tell me how to reinstall Windows 8 on the Yoga 13 when the recovery image is lost or damaged?

    hi Chevex,
      Thanks for using Lenovo Community Forums!
    In the event that the Recovery partition is not working the only option is to use the Recovery CD that you can create when you first got the computer.
    but if you were not able to create a Recovery CD and the Onekey Recovery is not working.
    You can get the Recovery CD from the Software Department (Fees may apply to the discs)
    you can contact the Hardware Team again and ask to be transferred to Software team for purchasing RCD

    Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
    Let's try something relatively simple first. Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
    If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

  • How to reinstall Windows 10

    Hi, I have a laptop with Windows 8 in the factory image.I installed Windows 10 but had some issue with 3rd party softwares. It's a general question, not related to a laptop model.  How to reinstall Windows 10 ? Do I need to put back the factory image ? It's seems the Windows 10 upgrade works only with Windows 8.1 With the factory image, the steps will be: -Restore the factory image
    -Install all windows update in Windows 8.0 to get the Windows 8.1 update
    -update drivers
    -Install Windows 8.1
    -Install all windows 8.1 update to get Windows 10-Install Windows 10
    It's seems to be a very long process.
    What's the recommended way to reinstall Windows 10 ?
    Thanks

    I don't want to do a clean. I don't want to install every driver. Is it possible to upgrade the Windows 8 factory image (not 8.1) directly to Windows 10, keeping all drivers ?  There is 144 important update in Windows 8, only to have access to Windows 8.1 installation page in Windows store.  I don't want to take one week to install Windows 10
