I change iMac hard disk from basic to dynamic in windows 7

I change iMac hard disk from basic to dynamic in windows 7, after restart windows I saw that there is not any OS X for selecting by press and hold "Option" key.
I don't have any backup and the original DVD from the seller. I live in Iran and here there is no any Apple seller or supporting center.
What should I do to have OS X again ?

Welcome to Apple Support Communities
You probably erased the hard drive by doing that. If you have got a Mid 2010 or later iMac, you can use Internet Recovery to reinstall OS X > http://support.apple.com/kb/HT4718 Hold Command, Option (Alt) and R keys while your computer is starting.
Then, open Disk Utility, choose your hard drive at the top of the sidebar, go to Erase tab and erase it in "Mac OS Extended (Journaled)". Finally, close Disk Utility and reinstall OS X.
If you have got an older Mac, call Apple to get replacement DVDs > http://support.apple.com/kb/HE57

    It certainly sounds like a bad HD to me. Back up your data and then take it in or call Apple.

  • Created second partition in bootcamp Windows and converted whole disk from basic to dynamic

    Hi everyone. I don't post here often however I hope the following helps someone else down the road.
    I currently user ML and have bootcamp installed. I needed more space on my ML partition so decided to free up space from bootcamp. Going about this completely the wrong way I booted into my bootcamp partition, ran the computer management app and shrank my boot camp partition by 8 GB. This created free unused space which I decided to format over to NTFS with a view to booting back into ML, deleting and adding to my ML partition (how wrong was I).
    Prior to completing the format of the newly created free space in bootcamp I was presented with the usual 'yes' / 'no' warning dialogue saying something along the lines of 'formatting this disk from basic to dynamic will prevent any installed operating systems from booting'. I made three monumental blunders at this stage: a) not reading the dialoge box b) completely disregarding the severity of the warning in the diaglogue box c) (you guessed it) pressing 'yes'.
    The moment I pressed yes it was the start of a four hour feeling of grief as I thought of the last 6 years of my life wiped from below my nose with no time machine backup.
    Upon rebooting bootcamp to get into ML the reality of the situation hit home as no OSX boot, no apple logo, no boot sound, my mac is trying to boot into windows without the option key being held in or warning to present me with a BSOD.
    One thought in my mind: "oh Sh*t!!!"
    3.5 hours passes and much reading online, learning of linux commands, downloading of linux distros, finding out how to install software and successfully setup a bootable linux usb and I'm typing this up on my mac while I time machine my data away to a freshly formatted external drive. Many lessons learned.
    This is what I did amongst the vacating of my bowels and absorption of much nicotine.
    There are two pointers to this guide. I was lucky enough to have another computer at hand to conduct the research and create a bootable usb. It a windows 7 toshiba z930. So you're going to need at a minimum: another computer (windows for the guide), a usb stick 2~4GB should be ok.
    1) download a linux iso, I downloaded ubuntu, you can download what ever you like, but you're going to need linux (the rest of my mini guide will use ubuntu 13.10 during examples) http://www.ubuntu.com/start-download?distro=desktop&bits=64&release=latest
    2) download Universal USB Stick Installer 1.9.5.1 (from now on as UUSI) http://www.pendrivelinux.com/downloads/Universal-USB-Installer/Universal-USB-Ins taller-1.9.5.1.exe
    3) plug in your usb drive. make sure there is nothing on it that you need to keep as it will be formatted and lost. also plug your mac into a router connected to the internet. this will help prevent any issues with wireless drivers when booting into ubuntu later on.
    4) once the downloads are complete, run UUSI, get past the prompts until you get to the 'setup your selections page'
    5) (A) select 'ubuntu' from step 1. (B) browse to your freshly downloaded ubuntu iso in step 2. (C) tick show all drives. (D) select the drive letter of your usb in step 3. tick we will format *drive letter here*. (E) depending on the size of your usb set some persistent storage - I had an 8gb usb to hand so I set 1GB, less will probably do. (F) double check your settings and click create then let the program do it's thing, it can take some time depending on the speed of your usb drive, mine took 10 mins.
    6) safely remove the usb and plug it into your mac, turn the mac on and hold the option key, once the usb drive is found hit enter and select ‘try ubuntu without installing’
    7) wait for the ubuntu os to load and click the settings icon from the left tool bar
    8) under settings click user accounts
    9) click the + symbol in the bottom left hand corner
    10) select administrator from the account type box and type a name for your account then click add
    11) select the account and change the password, then confirm it and click change
    12) go back to the desktop and select the power off symbol in the top right hand corner and select your name from the list, this will log you out of your current session and ask you to log in under your newly created login
    13) once logged in click the settings icon again from the left hand menu and under settings go to software and updates
    14) in software & updates under the ubuntu software tab tick ‘community maintained free and open source software (universe)’ and ‘software restricted by copyright or legal issues (maintained)’ then click close and close the settings window. Also check at the bottom of this window under ‘installable from cd-rom/dvd’ for two entries ‘cdrom with ubuntu 13.10 ‘saucy salamander’ - uncheck on of these entries if both are the same. Not sure if this was just me or a common problem. I found that trying to do the apt-get update would run into errors at the end if one of the entries wasn't deselected.
    15) hold ctrl + alt + T to bring up the terminal
    16) in the terminal window type sudo passwd root then enter a password for the account
    17) in the same terminal window type sudo -i and enter the password given from step 16 if requested
    18) in the same terminal window type apt-get update and wait for the update to finish without errors
    19) in the same terminal windows type apt-get install testdisk and wait for the installation to finish without errors
    20) in the same terminal window type testdisk
    21) select create log and then the drive you want to work on e.g. your main apple OS hard disk then select proceed
    22) select your file system type - for my ML installation I had to select ‘EFI GPT’ I don’t know if this will be the same throughout all macs / macbooks
    23) select analyse, the step should take less than a few seconds and testdisk may report back errors with the partitions or it may proceed to the ‘current partition structure’ screen. If errors are displayed proceed past them until the next screen.
    24) at the ‘current partition screen’ select quick search, you will have an opportunity to backup your drive here. I won’t go through this step (never learn) as I did not complete it myself
    25) after the searching has completed all the partitions on the disk should be shown. Find your OSX partition using the size reference at the bottom by pressing the up and down keys. Once you have found the partition that relates to the OSX partition that is failing to start hit the right key to make it a primary partition a ‘P’ should show to the left of the partition data. I had to make sure my EFI System and Mac HFS (155GB) partitions were marked as primary.
    26) hit the enter key to continue to the next screen and use the right arrow key to select ‘write’
    27) the program will warn you it will write the partition table so hit ‘Y’ and a confirmation should be displayed that this has been successful.
    28) reboot the computer and remove the USB stick (i removed it at the white loading screen after the reboot, not sure if it makes any difference)
    29) allow the computer longer to boot, mine took about 35 seconds to show the apple symbol whereas it normally took between 3~7 seconds before I destroyed it.
    30) get into OSX and backup everything to time machine or whatever you use then it probably a good idea to kill off your bootcamp install and refresh your mac from the fresh backup.
    Hope this helps someone. I couldn’t find anything conclusive on the net when I ran into problems (all my own fault really for not reading the dialogues correctly) however I used bits from multiple forums and found out parts myself especially the linux parts as I don't know the os at all . Certainly won’t be making this mistake again anytime soon.
    Well I’ve had an awful night and have work in two hours but at least the last 6 years of my (now backed up) life is intact and in my hands. I’d rather lose a night of sleep than lose all my data.
    Sorry if some of the stuff above is wrong as I don't do this thing on osx / linux at all really. At least it might point you in the right direction.

  • Help!! I need to recover my photos on my failed iMac hard disk

    I need some help in recovering my photo's on a failed imac hard disk......
    The history to this is that I received the cursed flashing folder with a question mark (?) when I tried to boot into my normal OSX Maverck on my imac - I researched this and there was a possibility of a hard disk error.
    I booted off the Mac OSX Snow Leopard CD to access Disk Utility to see if I could repair the hard disk - no luck! I couldn't repair it.
    I then installed a new version of OSX Snow Leopard on a external hard disk connected to the Imac through the USB - I then upgraded this version of OSX Snow Leopard to OSX Maverick. This allowed me to reboot the Imac off the external version OSX Maverick. I could subsequently see the failed hard disk on File Manager and have access to all the files on the main account. I don't however have access to other accounts (my wife's) where I store my photo's as there is a folder with a red minus sign denying me permission - I tried to change permission on these accounts but when I right click on the folder and select "Get Info" the permissions tab is greyed out denying me the ability to change permissions.
    How do I change permissions on the failed hard disk from my external copy of OSX Maverick? How do I get access to those files so I can receover the photo's?
    My ulitmate goal is to recover all the information on the failed hard dsik so that I can reformat the hard disk.
    By the way, I tried recovering the photo's using Time Machine but the last history I have is December 2011 which is 2.5 years out of date - something must have gone wrong! I don't want to receover this and lose the most recent photo's on the failed hard disk. Another question with Time Machine - if I perform a back-up today, will I be able to recover the data after I reformat the hard disk - my worry is that I'll only be able to get back to where I man now which is not being able to access the data on the folders that I don;t have permission on.
    I really appreciate the groups assistance.
    Lightning_rabbit

    I can think of several ways to get the files off.
    One is to create a root (super user account) user whcih will have access to everything. Another thing is to duplicate the other accounts that were on the failed drive on the new one and then log in as that user and move them over.
    A link to create the root user is here:

  • More than 1200 bad blocks do I need to change my Hard Disk

    Hi
    my hard disk on a Macbook pro has more than 1200 bad blocks do I need to change my Hard Disk
    Thanks for your help

    yousseffromlimoges wrote:
     my hard disk on a Macbook pro has more than 1200 bad blocks do I need to change my Hard Disk
    What software and version did you use to determine you had 1200+ bad blocks?
    Was it compatible with Lion?
    Run the scan again and take a screen shot of the results and make sure to save it to a external media and disconnect it, you will need this to perform a warranty call and have the drive replaced.
    After you have backed up your files to a external storage drive and disconnected it.
    Hold Command r upon rebooting and enter the Lion Recovery Partition and run Disk Utility, see if the drive needs repair. I suspect it does. Check the smart status too.
    Follow the
    Restoring OS X 10.7 (new drive, total reformat method)
    https://discussions.apple.com/message/16276201#16276201
    Also make a clone of your OS X Lion Partition on a external drive, this way your prepared if the drive dies, you can option boot off the clone. If you get a new drive you have a copy of Lion Recovery on the USB.
    It's highly unusual for a drive to have 1200+ bad blocks, the Zero Erase Free Space will confirm it as it's going to use up all your spare blocks.
    The drive will likely brick, which you then can option boot off the clone.
    Schedule a Apple warranty/AppleCare call if your under it, or order a new drive online from OtherWorld Computing "kits", iFixit for videos or other Mac places online.
    http://eshop.macsales.com/installvideos/
    You can read my link provided how to format the drive.
    However if your Zero Erase Free Space turns out fine, then I suspect the software you used or perhaps something else is wrong with your OS X not correctly reporting your drives data characteristics correctly.
    You could be spared a costly repair if that's the case.
    Good Luck.

  • Moving Hard Disk From one Mac to Another

    I am thinking of buying a new macbook. I have the C2D 2.16 Ghz right now. So if I would buy, lets say the new 2.4 Ghz model, could I just take the hard disk from the one I use now and put it into to the new Macbook?
    Would it boot up?
    Thanks!

    As i understand you already have a MacBook and your thinking of buying a new one, to witch you want to have all your present data.
    Instead of removing the physical HD from one and reseating it in another you cloud try one of these options out:
    1.
    If you have 10.5 on your present MacBook you might think of using TimeMachine:
    http://docs.info.apple.com/article.html?path=Mac/10.5/en/15638.html
    -great feature restores your whole system as you see it
    2.
    You have a utility called Migration Assistant, you´ll find this in Applications>Utility folder:
    http://support.apple.com/kb/HT1554?viewlocale=en_US
    3.
    Use a firewire cable to transfere the information you need.
    Best of luck.

  • HT5313 How can i change my hard disk up to 250 GB or 500 GB ?

    Can i change my hard disk up to 200 GB or 500 GB ? if i can,how should i do ?

    Clone backup current drive to an external disk (SuperDuper or Carbon Copy Cloner). The external disk should be a FireWire drive so you can boot it (I believe the White MacBooks only booted external FireWire drives). You should test booting the cloned external before continuing.  Or you could clone the current MacBook drive to the new replacement drive, which could be done via USB or FireWire.
    If I recall correctly, remove the battery, remove a metal shield, pull out the current drive, remove the bracket, attach bracket to new drive, slide new drive back in, put metal shield back on, put battery back in.
    If you cloned directly to new replacement drive, boot up your MacBook and enjoy.
    If you cloned to an external FireWire, boot the external cloned FireWire drive,  and clone it back to the new replacement drive.
    If you consider your data valuable, have yet another backup to a different drive before starting just to be safe.
    There should be YouTube videos that will show you how to do this, or search MacSales.com for how to videos.

  • Unable to access TC hard disk from PC

    I have been unable to access the TC wireless and hard disk from my PC. I have both a Mac and a PC...the Mac works fine. I'm not using the TC to access the internet I just want to use it for back up and file storage for now. The message i get from the pc when i try to access the airport disk is "could not connect to the disk. Make sure NetBIOS is enabled and try again (53)."
    I have tried to add the IP Address to my Norton software, I have even disabled Norton and that didn't help. I have tracked down the secret location of the NetBIOS and made sure it was enabled...but i get the same message.
    Anyone have any other ideas? I love the TC for MAC but i need it to work for both systems or I'm going to have to take it back! Please help!

    Ok...I stumbled onto the solution after being told by several people to have windows rebuilt and almost charged $130 from Dell Tech Support!
    While attempting to share files from my Dell to back up on my Mac in order to reformat windows...yea it was getting to that point...Windows had me run the network setup wizard. During the set up there is a "file and printer sharing" choice to make and the default is of course "turn off file and printer sharing" which is of course the key to accessing the TC.
    I did complete the setup for a new network, renaming the workgroup and making sure the other settings jived with all the TC settings I have thrashed through for nearly two weeks.
    I hope this saves someone a little time and a lot of frustration. Thanks to all the other posts about this issue, it was good to know that other people face the same type of problem and there were a million ways around it.

  • At only 15 months of age, my MacPro crashed yesterday! Any idea how I can save my hard disk from being destroyed if I hand it in for repair?

    At only 15 months of age, my MacPro crashed yesterday! Any idea how I can save my hard disk from being destroyed if I hand it in for repair?

    Open it up. Buy a new replacement drive. Install Mac OS. Then give it to them if you still have trouble.
    As for the install failing,
    I never do the older "archive and install"
    I format and initialize first, even zero the drive, and only then install.
    of course all the data is lost.
    Data Rescue 3 demo can scan a drive but you need to have setup a 2nd boot drive to work from, AND you would need part of that 2nd drive partition for recovery of data. 30-50GB system partition and 150% the size of the drive you want to recover.
    TimeMachine I never adopted or liked but 350% and would only use as secondary backup with cloned copy of your drive.
    Backups can be scheduled, run at night or weekend or both, a weekly clone and daily sets.
    Disk Warrior 4.2+ is another $100 (DR3 is about same but demo is free to try).
    A spare external drive case $30? and TWO hard drives, a replacement and backup/recovery $100 each?
    Just some ideas to throw out there....
    Bootable clones though you will find are very useful, handy.
    I like the small 40GB emergency boot partition - put one on your TimeMachine drive etc.
    LION: the one good thinig: it has a recovery mode partition and new Macs have "net install" feature and minimal hardware diagnostic over the internet to do Apple Hardware Test. Lion $30 and might actually want to install it on external.
    So DO try installing OS X on one of your external drives - create 40GB volume just for that - if you can please.

  • Upgrading hard disk from 320 GB to 500 GB

    Hi Mac Gang,
    By how much will the weight of my 13" macbook pro increase by upgrading the hard disk from 320GB to 500GB?
    Thanks!

    It's not the size (space) of a drive that increases its weight, it's more likely the speed of a drive that affects its weight. A 7200 RPM drive generally weighs more than its 5400 RPM counterpart (given the same model and same manufacturer), regardless of the amount of disk space in GBs. (The weight difference between these two different speed drives is probably only about 10-20 g.)
    FYI: Data on a hard drive has no weight, either. ; )

  • How can I optimize my hard disk drive usage and performance in Windows 8 or Windows 7?

    QuestionHow can I optimize my hard disk drive usage and performance in Windows 8 or Windows 7?
    AnswerThere are a few simple steps you can take to ensure your hard disk drive is used optimally.
    Use Toshiba HDD Protection
    Many Toshiba laptops come with a program called Toshiba HDD Protection pre-installed. This program helps to protect your hard disk drive from being damaged due to falls or impacts. By default, it should already be enabled. You might be tempted to lower the detection levels in this application, but doing so could cause your hard disk drive to be damaged. Remember that while the application can reduce the chance of damage, you should still avoid allowing the laptop to fall or suffer rapid impacts.
    For more information on this utility, see the following article:
    TOSHIBA HDD Protection
    Optimize the drive
    Windows 8 and Windows 7 optimize hard disk drives automatically through a process called defragmentation. Unless you've disabled this, you don't need to do anything. If you have disabled this and want to run the process, you can still do so.
    In Windows 8, search for "Defrag" at the Windows Start screen and select "Defragment and optimize your drives."
    In Windows 7, search for "Defrag" in the Start Menu's search field and select "Disk defragmenter."
    You can use this tool to optimize your hard disk drives, allowing Windows to find needed files faster.
    Remove items from startup
    Some applications run automatically when Windows starts. This can add additional functionality, but it also decreases the performance of your computer. Sometimes you might want to disable certain programs from starting automatically.
    In Windows 8, search for "Task Manager" at the Start screen. Select the "Startup" tab. Select an application you'd like to disable from starting automatically and then click the "Disable" button in the lower-right.
    In Windows 7, type "msconfig" in the Start Menu's search field and press ENTER. Uncheck the boxes next to applications you'd like to disable from starting automatically.
    You should be sure of the purpose of an application before disabling it from starting automatically. Some applications might be important. If in doubt, you might consider searching on the Web to discover more information about a program. Remember that if you find that you disabled something vital, you can always re-enable it.

    QuestionHow can I optimize my hard disk drive usage and performance in Windows 8 or Windows 7?
    AnswerThere are a few simple steps you can take to ensure your hard disk drive is used optimally.
    Use Toshiba HDD Protection
    Many Toshiba laptops come with a program called Toshiba HDD Protection pre-installed. This program helps to protect your hard disk drive from being damaged due to falls or impacts. By default, it should already be enabled. You might be tempted to lower the detection levels in this application, but doing so could cause your hard disk drive to be damaged. Remember that while the application can reduce the chance of damage, you should still avoid allowing the laptop to fall or suffer rapid impacts.
    For more information on this utility, see the following article:
    TOSHIBA HDD Protection
    Optimize the drive
    Windows 8 and Windows 7 optimize hard disk drives automatically through a process called defragmentation. Unless you've disabled this, you don't need to do anything. If you have disabled this and want to run the process, you can still do so.
    In Windows 8, search for "Defrag" at the Windows Start screen and select "Defragment and optimize your drives."
    In Windows 7, search for "Defrag" in the Start Menu's search field and select "Disk defragmenter."
    You can use this tool to optimize your hard disk drives, allowing Windows to find needed files faster.

  • How do I remove the Hard disk from computer? I have an old iMac, model M5521 circa 2000.  I need to wipe the disk clean to DOD specs before donating it.

    I have an iMac Model M5521, circa 2000, which I must wipe the hard drive clean to DOD specs before donating it.
    I have the DOD software on another non-apple computer.  I need to remove the hard disk drive from the iMac to do this.
    How do I get to the hard drive?  I find only two screws on the back of the monitor/case and they do not help.  What am I missing?
    Thanks

    It's not too hard but you have to take off the bottom cover of the case. These instructions shoudl show what yo uneed to do.

    I pulled the original 10G hard drive from our M5521 and replaced it with a larger one. The whole thing took under 45 minutes, including the 15 minutes it took me to recover a screw that fell into the works.

  • What is the best way to re-install my apps data when changing the hard disk

    My MacBook (120Gb disk) is finally full and I have ordered a 500Gb disk to replace it.
    I am fine with changing over the disk but can anyone tell me the best way to reload all my apps and data from the present disk please?
    I have a Time Machine backup on a Network disk, a copy of SuperDuper and also my original 10.5 OSX install disks.
    Thanks

    Roger, since you have SuperDuper, I think the easiest thing to do would be to make a clone of your current hard drive to the new one when it arrives. You will need an external enclosure for the new drive; make sure it's formatted to Mac OS Extended (Journaled); Disk Utility will do this for you. Then connect that new drive via firewire or USB, and create the clone from your current drive using SuperDuper. Next, remove the internal drive from your Mac, insert the new drive and boot up. You can then place your older drive in the external enclosure to use for extra storage, though it won't be large enough to use as a cloned backup with SuperDuper.
    Good luck!

  • How can I completely erase the iMac Hard Disk without the password?

    I inherited an iMac running OS 10.9.5. I want to completely erase the Mac Hard Disk. I know the Administrator's name but not his password. He is deceased. I think I reset the password but don't know to inform the Keychain or accomplish the erasure.  How is this done?

    Unless the iMac does not have a Recovery HD, you should be able to restart into Recovery Mode (Command+R) and use Disk Utility to erase the Macintosh HD. You don't need any password. Or are you saying the drive is encrypted (Filevault 2) and you need a userID/password to unlock/decrypt it?
    If you want to reinstall OS X Mavericks, you may need your Apple ID/password assuming you downloaded it when it was available from the Mac App Store. Otherwise, depending on the model you might be able to use Internet Recovery (Command+Opton+R) to reinstall OS X Lion or above which ever the machine shipped with then upgrade from there. Or if it came with Snow Leopard or below you will need the install DVDs.
