How to recover my bootcamp

Hi I'm Macbook pro user, recent days i got updated my os program as os X lion, but after updating I lost my bootcamp disk and windows programs.
How to recover my bootcamp disk.... Help me please....

No. You have found your lost NTFS partition. Here is a table I use to validate that it is reasonable.
GPT 3 Start
GPT 3 Size
GPT 3 End
NTFS Start
Byte Offset
NTFS Size
NTFS End
205722144
1269536
206991680
207065088
73408
105515001
312580089
So your 'numbers' look as follows...
Sudo gdisk /dev/rdisk0
P  (print the full list of parts)
D  (delete)
4  (part 4)
N  (new part)
4   (part 4)
207065088
- Start offset in bytes  (start point for Bootcamp part)
+105515001
(Size offset as opposed to End offset)
0700     (Windows part type)
P           (print list of all parts just to see what changes will be made)
W         (Write the new GPT)
Y           (Yes! really write the new GPT)
This will delete and re-write the GPT partition info for /dev/disk0s4. 
Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR
Sudo gdisk /dev/disk0
P  (Print list of parts)
R   (Recover)
H (chooses Hybrid)
Partitions numbers to be hybridized: 2 3 4
Y (Good for GRUB question)
N (part 2 flag)
N (part 3 flag)
Y  (part 4 flag make bootable partition)
W  (Write the new MBR)
Y    (Yes! write the new MBR)
Reboot
Test 1 - Does Bootcamp Volume show up in Finder?
Test 2 - Can you files in Bootcamp Volume?
Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?
Test 4 - If Test 3 is successful, select Bootcamp and Click Restart.
If you see a hanging underline cursor at the top left on a black screen, and it does not proceed further, you may need Windows Startup Repair or a tool called EasyBCD.

  • How can I uninstall Bootcamp and Recover the partition for the Mac HD

    How can I uninstall Bootcamp and recover the partition for the IMac HD?

    Boot into OSX.  Go back into the Bootcamp utility in the Utilities folder and re-run it.  It will give you the option to remove the Windows partition and make the OSX partition fill the whole drive again.  OSX will NOT be lost in the process.  No re-installing necessary.  Only takes a few minutes or less to complete.

  • The guide to bootcamp assistant states that bootcamp can only be installed on a drive with a single partition. New Macs with Lion preinstalled have two partitions - the second is a recovery partition.  How do I install Bootcamp?

    Late in August 2011 I took delivery of a new 27" iMac with Lion preinstalled.  I need to run Windows as well. Following Apple's written suggestion, I printed off the then current 12 pages of the document "Bootcamp Installation & Setup Guide" which clearly stated that the hard drive you were going to install on had to have on it, before install, a maximum of one partition.  Using finder and disk utility I determined that there was only one partition.  Unbeknownst to me, there was (is) an additional hidden (from those two pieces of software) partition on the disk.  As of machines delivered new with Lion preinstalled, Apple has begun to include a "recovery partition".  In that partition there is a copy of the software necessary to reinstall Lion via a download from the Apple App Store.  Not knowing the partition was there, I cranked up  "Bootcamp Assistant" which nicely offered to repartition my hard drive creating a "Bootcamp Partition" in addition to the existing.  I told it how big to make each and hit the do it button, subsequently destroying my operating system.  Oh, it very nicely told me, after the damage was done, how many partitions were REALLY on the disk and that I could not install Bootcamp cause there were too many partitions.
    Luckily the the Recovery Partition, which at that point I knew existed, was not harmed and after doing some research on another compter, I used it to once again download Lion from the App Store and reinstall. So, I have recovered but am still stuck with the problem:  how do I install Bootcamp in this new environment?

    First you need to seriously back up your Mac.
    A clone is an exact duplicate of your existing Mac HDD. Merely copying and pasting a drive will not make a bootable backup. In case of problems you can boot from an Ext HDD clone and use the utilities to repair, reformat, or clone the Ext HDD back to the internal Mac HDD.  While Time machine back ups are easy you can not boot from it. The best thing to have for any kind of problem is a bootable clone backup on an external drive. Some even have two external backup drives in case one fails. There are two good apps for cloning named SuperDuper and Carbon Copy Cloner.
    In dealing with the recovery partition a simple approach is to clone the Mac partition to an external disk then re-partition the Mac to a single partition (GUID partition table) . Then clone the external disk clone back to the Mac. You will now have only one Partition and Boot Camp assistant sould not object.
    Some have recommended getting rid of the recovery partition while others have advised not to do this. If you have the Lion USB Thumb Drive you do not need a recovery partition so can discard it without concern. There is another way to get rid of the recovery partition if you decide to do it but first be sure to have a backup of your Mac ( I know I sound like a nagging mom but many dead computers have been saved by this simple precaution).
    Use Disk Utility.
    1) Make the Recovery visible in Disk Utility by using a program like Secrets:http://www.macupdate.com/app/mac/27025/secrets or MacPilot:http://www.koingosw.com/products/macpilot.php (15 day free trial).
    2) Highlite the Recovery partition and Control click it and select Mount the partition.
    3) With the Recovery partition highlited, erase the partition, you'll get an error message, ignore it.
    4) Now highlite the top identity of the hard drive and select the partition tab.
    5) Highlite the Recovery partition and press the minus sign.
    6) Click and hold on the bottom edge of the partition above and drag it to the bottom, if it doesn't go there automatically, the press apply.

  • How to recover re-installation partition (iMac)

    Hi guys,
         I recently installed bootcamp on my computer (Windows 7 Home Premium x64) which glitched out and deleted my install partition and my normal Mac OS Lion partition which means it is no longer usable as an Apple Mac. I was wondering if any genius out there had any idea on how to recover the OS or the install drive. Any advice is much apreciated.
    When I got my mac it came with Mac OS Lion installed already if that helps. It was also brand new

    If your computer came with Lion, it means that you have Internet Recovery. You should use it in case that you can't access to Recovery HD like in your case or when the hard drive is damaged. Read > http://support.apple.com/kb/HT4718
    Note that you will have to delete the Windows volume. Follow these steps:
    1. Hold Command, Option (Alt) and R keys while your computer is starting, and open Disk Utility.
    2. Select the hard drive at the top of the sidebar, go to Erase tab and erase the drive.
    3. Close Disk Utility and reinstall OS X.
    After reinstalling OS X, reinstall Windows. To do it, follow these steps > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.7.pdf

  • How to recover my SSD from simple drive under windows

    hello,
    it starts when i used the bootcamp to partition my 256GB SSD to install windows in my MBA, the target is to have iOS & WIndows7 each in separate partition of course + 3rd partition for my data.
    so everything went all right until i get to Windows manager>driver manager then shrink the windows partition, this done successfully, and the new Unknown partition appears, accidentally i converted it to a simple Drive, this converted all the SSD to simple drive.
    later once MBA reboots, Mac and Recovery partitions are not there, they disappear.
    the question is
    1. either how to roll this activity back?
    2. or, how to recover my MBA to factory defaults?

    How old is your Mac Air? If it is one of the late 2011 models or a 2012 model then you can use Internet Recovery to Re-Partition the drive as ONE Partition. You need to do that to clear out all the problems you now have.
    To use the Internet Recovery system you hold down either Command+r keys or Command+Option+r keys at startup and hold them down until you see a Spinning Globe in the certer of the screen.
    If Command+r doesn't work then you use the Command+Option+r keys. One or the other will get you to the internet Recovery system.
    Right when you used Windows to repartition the Windows partition it screwed up your whole system. You CAN NOT do that, Ever. Once you create a Boot Camp partition to install Windows in you have to Leave it Alone and there is no other way to install Windows on a Mac that also runs OS X.
    There is NO way to FIX your system other then to completely wipe the drive be Re-Partitioning the drive as one partition and starting over with the install of OS X, Programs and personal files.
    Sorry but I thought I made that clear in my first post.
    If your system did not originally come with Lion installed and is older then a 2011 model then you will need to dust off the Original System Discs that came with your system and start with those as systems older then 2011 models can not use Internet Recovery.
    You can only have One Partition for Windows, the one you originally create with the Boot Camp Assistant program.
    You can have multiple partitions made by OS X and one of those could be formatted FAT so both Windows and OS X can use it.
    But with only a 256GB drive you are going to run out of space someplace, on OS X or Windows, and even more so if you again partition the drive to include a third partition.

  • How do I install Bootcamp on Windows 7.

    I have just installed Windows 7 on my Mac Mini and now I want to switch back to the Mac OS. When I hold down Alt while booting up to change OS nothing happens.
    The other option is to install Bootcamp to work with windows. It's already on my mac as I used it to install Windows 7. But there is no option to switch OS with Bootcamp as I can't find it on Windows 7. I've seen tutorials on how to install it with a disk but the Mac mini has no optical drive.
    How do I install Bootcamp on Windows??

    At first I was under the impression i had accidentily deleted the MAC OS but thankfully I haven't. I did a system restore on Windows and when it restarted I held Alt and I could select my OS.
    But I still don't have the shortcut to bootcamp showing in windows. How do you make a bootable USB for Bootcamp?

  • How to recover Deleted file from HARD DISK

    By mistake my entire AVCHD file of 90 Mts  duration was deleted from my Hard Disk, this  I realised after a week., in the meantime I have not added or deleted any file from this hard Disk.

    Can anybody in the forum help me and suggest how to recover my deleted Video from the Hard disk

    Hi, hard disk data loss is actually a hard task for many users 'cause most of them think this kind of problems is a complicated situation. Here are some tips you need to know after data loss happened.
    1. If you meet the file loss situation, keep calm and stop using your computer to do any read or write operation until you find the way to recover the lost files because any wrong operation.
    2. If you've lost a file, time is of the essence. As new files saved to Mac hard drive or storage devices, the original files gets overwritten. So do not use the drive or disk which your deleted files are stored before at all, until you have completed the scanning and recovery process.
    3. The system crashed or the files loss situation happens occasionally, so remember build a backup for the files periodically is strongly needed.
    4. If you meet the file loss situation again, stop using the Mac or storage device right now, use another computer to process the files recovery.
    5. Remember this, no matter at the normal time or after files recovery, build a backup for the files periodically is the best method to protect your files from data loss situation.

  • How to recover lost folders and files - Pls help, help...

    Some days ago I lost all of my 15 GB folders and files that stored in my Macbook Pro hard drive called DATA.  I brought my Macbook pro to an experienced computer tecnicians who providing data recovery services. To his and my suprise, after checking, scanning it a few hours, he said their is no way to recover because he did not find any trails at all.  The computer still seems working properly - I have no problem with any applications.  There are few other folders in the DATA hard disk containing pictures, computer programs still remain.  These lost folders and files contain mainly documents (word, excel, power point, pdf etc) which I accumulated in my many years working  !!!!.  I did not make a back up since last September partly because I think Mac is very safe.
    The computer with me all the time on that day and only my son used Power Point to make a simple presentation on that evening - he can not save it on the folders the he normally use - All the folders and files are gone.
    I will appreciate it very much if any of you can tell me what would be the possible causes and more importanly how to recover the lost folders and files.  They are very very valuable to me.
    Many thanks for your kind attention

    First, did the data actually get deleted, or is it still there somewhere?  Try searching the drive for some of the documents, perhaps it's all just in another folder on that drive.
    If it's truly gone, it's impossible for us to say what might have happened to make it unrecoverable.  Perhaps someone using the computer used Secure Empty Trash, or securely erased empty space on the hard drive.  Perhaps it was overwritten by other stuff before you noticed.  It's possible the hard drive is starting to fail, though this seems like an awfully specific problem for that to be the issue.
    Or perhaps the tech you took the computer to didn't know what he was doing.  Why not try recovering what you can on your own?  See Recovering deleted files.
    You should be aware that no computer is safe.  All computers rely on hardware that may fail and software that can have bugs.  You absolutely MUST maintain a good set of frequently-updated backups...  no fewer than two full backups of anything you don't want to lose.

  • How to recover photos after restoring iPod touch?

    Yesterday, there was an update for the iOS 6, I believe. When I pressed the update button, a message popped up saying that there was a problem with my iPod touch 4G and that I need to restore it. I had absolutely no idea why that message would pop up in the first place because my iPod was working just fine. But I couldn't update my iPod to the newest version if I didn't do what iTunes says... so I was about to restore my iPod, but then I was worried that all of my photos would disappear. So I decided to update my iOS later so that I could transfer all my files on to my computer. I then unplugged my iPod, and tried to turn it on but the home screen wouldn't pop - no matter what I did, all the screen showed was an itunes icon on top with a USB plug-in cord at the bottom. So I had no choice but to restore my iPod. The thing is, once I restored my iPod and all, my photos were all gone and I did not use iCloud as a back-up since a few months ago. All of my recent photos are now gone and I have no idea how to recover them. I've tried programs that aim to recover deleted photos, but they didn't work.
    Is there a way to recover photos after restoring the iPod Touch?

    Hello,
    It is very important to backup your device to the computer before updating or restoring.
    You can restore your device to a previous backup, all the photos that were there when you made the backup should return with it, but I'm afraid that any photos taken or saved after the last backup are unrecoverable.
    I hope this helps.
