How to restore a corrupted partition

Hello everyone!

I have had this problem for a while and posted on the multiple mac forum, but no one ever knew how to fix it.

Last year, I tried to install windows on my mac, but for some reason, it didn't work and I'm now stuck with a score of 100 GB "Untitled." I'm running out of space and I'd really like to use these 100 GB.

People told me to run bootcamp and understand but when I run the bootcamp, it says "Startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted in a single volume in Mac OS extended (journaled) or already partitioned by Boot Camp Assistant to install Windows. "I have no idea what it means.

At that time I kinda dropped on installing windows (although it would be nice), but all I want is to get my back to 100 GB!

Thanks to anyone who can help!

Kevin

Can you post the output of the following commands in OS X Terminal?

diskutil list

Cs diskutil list

sudo TPG - vv - r see the/dev/disk0

sudo fdisk/dev/disk0

The "sudo" commands will prompt to enter your password, and there do not appear to come back. You can also see caution against improper use 'sudo' and the potential loss of data due to an "abuse" of the order.

  • How to restore after deleting a partition in unallocated space on my hard drive?

    HI, I have recently removed a partition of my hard drive on windows Vista Home Basic. I removed it because I needed to find the hard drive space on the main user profile.

    I found, after following the instructions on how to remove the partition that the partition has been deleted, but the space was not available for use on the main user.

    I couldn't find any information on how to restore the space unallocated on the C: drive, so if there is someone out there who can help me, I'd appreciate the help! : o).

    Hi geddron1976,

    Is "unallocated" space right next to the C: partition, that is to the right of the C: partition? If yes go to control panel and click the Administrative Tools icon. In the Administrative Tools window, click computer management. In the window of computer managgement, click on disk management and you will then see a view of your disks. Click right on your C: drive, and in the menu drop-down, select "Extend Volume".  A wizard will appear. In the 'select amount of space in MB' type the amount sdpace you want to extend the partition. If you want this then let the total in the State. Now, click Next, followed by the finished product. The c: drive should now be extended in your unallocated space.

    If the C: partition is 'no' right next to the unallocated space, then you will not be able to extend the partition - not with the windows disk in any case management application. To do this you will need a third party application of partitioning, it is also a little more complex.

  • How to restore partition factory settings after installing Win 7 Professional and after having lost everything as a result.

    I have a netbook with a partition that has win7 starter installed.  I unfortunately poorly installed windows 7 Professional and now have nothing available which was originally on the computer.  Everything was wiped clean including my ability to use / access my wireless, ethernet controller, pci, etc..  I tried repeatedly to recover the partition back to factory settings, but it won't give me the option to select the partition.  I guess that's because they are all two Windows 7.  Can you help me get it back to windows 7 edition starter of the partition so I can restore all the factory settings and programs.  I haven't lost any information or files that I loaded win7professtional as soon as I turned it on.  I have restore points, images, etc.

    When I installed Win 7 Professional, not old Info windows.old file but I don't know how to access that is.

    (1) can be used to uninstall Windows 7 and return your PC to the previous version of Windows.
    (2) contains a backup of all your files of data, documents, photos, Etc. from the previous version of Windows.

    If you don't need either of these two options can delete the Windows.old folder. In your case if you can access the "recovery Partition" to restore the windows and then back the Windows.old folder before you begin.

    Note: Option to change Windows Explorer to see the Windows.old folder:
    Click on start and enter in the box "Search": "hidden" (without the quotes)
    Click on the "Show the hidden files and folders" option at the top of the list.
    In the "Folder Options" window
    Click the 'view' if it is not already selected.
    In the list "Advanced settings" locate "hidden files and folders".

    I tried to open a catalog that was on a disk hard Ext. as usual. I got the message that she may have been damaged and cannot be opened. I tried the option to attempt the repair.

  • Re: Satellite A300 - how to restore the original condition?

    Hello

    My computer freezes for a second or 2 from time to time and Toshiba support told me it might be a software problem. I don't think, because he began the day I bought the laptop and the display driver keeps on the work stoppage, but because I said that if it's a software problem.
    I would have to pay for it, I want to try everything before sending it for repair. This is why I would like to restore my Satellite in its original state as he was just at the moment where I bought it.

    So basically I have 2 questions:

    1 - does anyone have any idea why it keeps freezing on me? And what I should try to do to fix it?
    2. can someone tell me how to restore the laptop to its original state?

    Thank you very much Dina

    Hello

    To determine if it of a software problem or not, you need to restore the factory setting and if it doesn't work you can go to an authorized service provider. They can repair the laptop for you.

    The factory settings can be restored with the Toshiba recovery disc. I guess that your laptop has been delivered with Windows Vista, if you have options to restore factory settings: the Toshiba disk recovery or HARD drive recovery service.

    HARD drive recovery function formats the first partition of your laptop and install Vista again with all the drivers and tools of Toshiba. It is an image that is stored on the second partition of HARD drive in the folder HDDRecovery.
    If you go into the advanced with F8 boot menu after you start the computer, you can start this feature of Toshiba. And then select Repair my computer and some Windows files will be loaded. Then, you can choose the function to drive HARD Toshiba Recovery and follow the instructions on the screen.

    The Toshiba Recovery disk, you must create first, or have you done this yet? Normally, you get a reminder of recovery message after the first start of the laptop that you must burn this disc. Therefore, you must the preinstalled Toshiba recovery disc creator and the image in the folder in HARD drive recovery will be burned on the disc. Then you have a startup disk that can restore the factory settings and HARD whole disc formats then back up your data first!
    The recovery disk is necessary if you have a new HDD or Windows start doesn t. Otherwise, you can use HARD drive recovery.

    I hope I could help a bit and now you understand how to restore the factory settings.
    If you have any other questions, please let us know! :)

    Good bye

  • Satellite L500 - how to restore the menu "repair your computer"?

    Hello world

    I have a laptop Toshiba L500, Yestaday I tried to restore the system to the factory settings (by pressing F8 at startup high and choose "repair your computer"). In the system has been installed almost, but at a stage of installation drivers to read memory cards and similar - there was a failure (the blue screen and need down) - after that - Windows 7 is not loaded. parsing errors (by means using a floppy disk to another Windows 7 install) says that the registry is damaged, cannot repair.

    but the main problem - when you press F8 at startup upward - there is no MORE menu 'Repair your computer' (!) . It is impossible to start Windows 7 predefined. So there's the hidden sector containing Windows predefined (I saw when loading a disc of hatch - Total order could start - and hidden sector was visible). All files in drive recovery HARD necessary are also available.

    How to restore the menu "repair your computer"? or how it is possible to start Windows predefined without pressing F8?

    > Hidden article exists, I saw it, there are all the files recovery HARD drive (which was in the laptop after buying), but I can't begin to recover Windows because I don't have menu not 'repair your computer' to start the laptop. He disappeared...
    Of course, the flag in the Advanced Start menu seems to be deleted and therefore drive recovery HARD option isn't available anymore.
    Probably the partition has changed.

    But in case of HARD drive recovery files are still available on the recovery partition, you can try to create the USB support of own recovery using of workaround:

    Please can someone help me?

    Hello sammi

    Yes, we can help you, but you should also use more than one phrase to describe your problem.
    No one knows what OS you are currently using.
    Do you use BONES that you got with your laptop?
    Have you changed the structure of partitions?
    You have created recovery DVD?
    Is the installation of HARD drive recovery work if your laptop is always the factory settings.

    When you press F8 at startup you can enter advanced startup options?
    Repair my computer option is listed here?

  • Equium won't start - how to access the recovery partition?

    Hi, my sister has a 2008 Equium A200-1V0 with Vista 32-bit, that no longer starts (probably due to damage of rootkit virus). It loads the BIOS but then goes to black screen with blinking cursor.

    F8 does not work.
    F2 goes to Phoenix TrustedCore Setup utility. The Toshiba hard drive and a CD-ROM drive are listed in hand and start in the right order.

    Using F12 I can get it to boot from a Win7 64 bit repair disc that I burned using my laptop.

    However, it does not recognize the operating system or any image or restore points (because it is 64-bit) but he will be responsible for command prompt.

    To * guest *, I can launch Notepad and when I click on file / open and double click on computer it shows 4 Hard drives as follows:
    Local disc (c :))
    Data (d :)) 42 GB free of 54.5 GB
    WinRE (e :)) 1.11 GB free of 1.46 GB)
    Boot (x :)) 29.0 MB of free space of 31.5 MB (which is used by the repair disk)

    So the C: drive is listed, but without ability.

    * CHKDSK *.
    CHKDSK c: /r and press return

    «The type of the file system is NTFS.»
    Unable to determine the status and version of the volume. CHKDSK is abandoned.

    3 P HPFS - NTFS 7477 118 2 14592 190 62 114307072 (data)

    * = Primary bootable
    When you perform a quick search, then P - list of files, the second partition it reports:
    "Cannot open the file system. Filesystem seems damaged. »

    So what I want to do is boot to Windows restore to drive E.

    My question is for Toshiba experts: If F8 does not work how to use the recovery partition?

    Laptop is:

    > THIS ISN'T MICROSOFT, TOSHIBA, AND GOOD PRODUCT DESIGN.
    I really put t know that should do better than to place the Microsoft sticker at the bottom.
    This product key and sticker on it's just proof that you purchased the machine with an operating system preinstalled and legal active OS version. This key belongs to original OS (recovery image) that you got with your laptop and it is not a kind of universal key that you can use for the activation of the operating system if you have made the decision to install the clean version of the OS.

    In General, this key is totally useless. While your computer you've got legal copy and this version, that you can install so often desired. It must not be enabled.
    > So my question still remains: can I recover my Toshiba laptop using this restore partition?
    If you want to recover using the Toshiba recovery image response is not. Cannot start HARD drive recovery facility.
    > Even with a dvd of Windows Vista is genuine, I can't reload the OS
    In my opinion you need make the clean OS installation using the clean installation or order original Toshiba Recovery disk on https://backupmedia.toshiba.eu/landing.aspx disc and install original (already active) recovery image.
