Bootcamp formated my 2nd mac partition

Hi All
I tried to use bootcamp to install win7 on my macbookpro. When I run the bootcamp and go to the partition adjust or delete step, bootcamp tried to merge my 2 mac partitions. I clicked continue. At last it failed and formated my 2nd mac partition. That partition is grey in disk utility. I can not see it in finder. I do not have timemachine backup for that partition.I lost all the data on that partition. Is it possible to get them back?

It appears you did not read or follow the Boot Camp instructions http://www.apple.com/support/bootcamp/.
Boot Camp will not work, as you found out, if your hard drive has multiple partitions. You will have to erase and format your hard drive to a single OSx partition. Make sure you save all your data before doing so.
You should also visit the Boot Camp forum where the Boot Camp gurus hang out https://discussions.apple.com/community/windows_software/boot_camp

Mac partition (hfs+) not visible in Windows after upgrade to Yosemite

Hi,
I'm using a MacBook Pro with two partitions, Windows 8.1 (Bootcamp) en Mac OS X. I upgraded Mac OS from 10.9 to 10.10 (Yosemite) recently.
After upgrading, the Mac partition in Windows is no longer visible. I need it to be visible, as I have files on that partition which I need to access in Windows.
I've checked the format of the Mac partition, which is HSF+. I have installed the latest Bootcamp driver (5.1.5621).
Any assistance would be appreciated.

I have an issue in my 13'' Mac after installing windows 7 with bootcamp I lost my mac journal partition

Hi,
I use the bootcamp to install win7 on my 13" macbook pro .. after the installation I got throw windows and try to change the windows partition size
things gone wrong and I got my mac partition lost ! and while trying to got it throw the recovery Disk utility show that it turns to fat partition !
so I couldn't do any thing with it ! couldn't reinstall the lion again .. the only way is to reformat it !! and this will make me lost all my things in it !
So I just need any solution or software to boot from it and converting or editing the partition file system to be journal not fat
by the way also in windows can't open the partition even it shows that it Fat format !

my dear it's fixed.
the problem is that I did not hold down the alt option key so solution is just to hold down the alt option key for a while.
thanks for your response

My external hard drive appears in bootcamp but not on my mac partition

This is intriguing. I own a macbook pro and run osx 10.6.8
I recently bought a new 1 tb hard drive and partitioned it. (300G for time machine and another for 700G for random things). It was working fine until I tried logging onto my bootcamp partition. I couldn't edit any files (due to the format of the drive), so I decided to relog back onto my mac parititon. Now the disk is grayed out in disk utility, under a different name and a different format type. I can read the files on my windows partition, but I cannot even access the drive on my mac partition. This drive is rather big, and I have no idea how I would even begin bcking it up... ( i don't have any other drives this large..)
Any ideas?
Thanks in advance!!

You wrote: "It's definitely formatted for windows...I have Disk Warrior, but it doesn't see my drive "DiskWarrior only works on disks in Mac OS formats, e.g. "Mac OS Extended" (aka HFS Plus or HFS+), "Mac OS Extended (Journaled)." It won't fix disks in MS-DOS/FAT32 format.
There are PC-specific disk utilities, akin to DiskWarrior for Mac, so if you have a PC as well, a PC disk utility might help repair the directory corruption if run from a PC.
External drives, whether they're formatted for PCs or Macs, can be subject to the same causes of directory corruption discussed in See my "Data corruption and loss: causes and avoidance" FAQ. Some of those causes have nothing to do with hardware failure and many are preventable.
Good luck!

Mac Partition fails but Bootcamp is fine

Hello
I'm having an odd issue where my MacBook Pro's Bootcamp partition is running fine, but the Mac Parition is acting up. I backed up the Mac side, booted into a Mavericks installation USB stick, wiped and formatted the Mac partition using Disk Utility, but can't seem to be able to install Mavericks still as it says the disk needs to be fixed (even though I just formatted it...)
Does this mean I need to re-format the whole disk, and not just the mac partition, to be able to do a clean install of Mavericks?
Thanks

So you mean that if the faulty sectors are in fact there, it could be a hardware problem, but just localized to a certain part of the disk?
Thanks!

Resizing Mac partition back to original size after deleting another mac partition (I also have a Bootcamp partition - unrelated to this issue)

Hello,
I originally had two partitions - Mavericks and Bootcamp. I created another partition to install Yosemite. Then deleted it. Now I have a grey space where the Yosemite partition was. I can extend the mac partition and click 'Apply' in Disk Utility but after a few seconds, it goes back to it's original position ('Grey space' is still there) and Disk Utility doesn't give any error. I just verified on another discussion that one other user is also having the same problem. Anyone know how to fix this?

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This will return your drive to one partition with OS X installed on it. Your Boot Camp partition will be gone, but after adding a third partition you would not be able to boot from Windows. When you use Boot Camp you cannot have more than two partitions on the drive: OS X and Boot Camp Windows.

Bootcamp files do not show up in mac partition.

Hi, my question is about retrieving files from bootcamp while I am on the mac partition. I used to be able to see a disk icon for my bootcamp on my desktop when I was on my mac partition, but ever since I installed Yosemite, I have not been able to see it on my desktop, or as one of the drives in my finder. From this icon, I was able to access files created in Bootcamp. I no longer can see this icon on my mac's desktop. I have no problem opening bootcamp when I press alt on startup, so bootcamp is not broken, but I would like to be able to access those files while I am in Yosemite again. Any ideas?
Thank in advance,

Clone a Mac Partition to an External Drive from within Windows 7 Bootcamp?

Anyone know if it is possible to clone the mac os x partition to an external drive from within Windows 7 bootcamp? I (like a few others) had a problem with the latest 10.6.3 update and I cannot boot into the mac partition but I can access it via bootcamp so I was thinking about trying to clone it to an external drive and then boot from the new clone and see if that works.
Appreciate your comments.

setup a 30GB partition on an external drive, along with a partition of 150% the size of your Mac OS X volume -- or larger.
Install OS X to 30GB.
While booted from DVD, before you install, you'll need to go to Utility Menu => Disk Utility to do the partitoning. While there, in DU see if you can repair your system.
And where is your TimeMachine or clone backup? The "Step #1: Backup before beginning your Boot Camp project."?
No way to backup or clone from within Windows, though you may be able to write to NTFS backup volume, UNLESS you bought MacDrive8 which allows read AND write to HFS+ from within Windows.

I just installed yosemite on my mcb pro mid 2012 and installed win8.1 with bootcamp. now i have the problem, when i'm using windows i don't see my mac partition in the "computer" window. there is only the "bootcamp (c;) partition? what's the problem?

i just installed yosemite on my mcb pro mid 2012 with a clean install. so i only had the new os x yosemite running on my mac. everything went perfect. than i installed win8.1 with the bootcamp assistant and also everything went perfect.
But here's the Problem:
When i'm using Windows 8.1 and i go to the "Computer" window where i can find my hdd partition "Bootcamp (c;) there is only this Partition. the mac Partition is missing.
so i am not able to read the files on my mac Partition.
Before i installed yosemite and win8.1, i was running mavericks and win7 on my macbook pro and i haven't had this Problem. i was able to see and read my mac Partition also on Windows 8.1???
is there any solution for this Problem???

New Hard Drive, Mac partition cloned and boots fine, but I can't seem to get my BOOTCAMP (windows) partition to boot! Any ideas?

Hello all!
I got a new hard drive for my Mac Book Pro and an enclosure so I could clone the old partitions on to the new drive.
So I...
Put the new hard drive in the enclosure.
Booted up off an install disk and ran disk utility.
Copied the Mac and Bootcamp partitions over to the new drive that was connected VIA USB.
Turned off the computer, took the old hard drive out and put it in the enclosure.
Put the new hard drive in the Mac Book Pro.
Booted into Mac OSX with no problem.
When I rebooted held down the option key to boot into the windows side, it didn't show up as an option.
When I went back into the Mac side, I loaded Disk Utility and saw that I had the Mac partition, the BOOTCAMP partition, and a bunch of unallocated space. When I went into the System Preferences and set the target boot drive to the BOOTCAMP partition and restarted, I got some crazy error about there not being any bootable info on it.
That's where I am at. I have found other posts with people who are having the same problem, but I have yet to find a solution that doesn't involve me buying some 3rd party software. I know it has something to do with (what is called in Microsoft world) the Master Boot Record, but I don't know how to modify that to reflect that the BOOTCAMP partition is a bootable logical drive. I remember in MS DOS land there was some command line FDSK /something command that you would run (I think it was /MBR) to reset the MBR. To me though, all of these terms are shadowy figures in the Ether.
What do I do???
-Ricardo
p.s. I read somewhere to boot off the windows 7 disk and run the system repair tools. I tried that and no change.

I got it. It CAN be done. At least on 10.6
How I made it happen (for free) on Snow Leopard:
1) partition, dupe etc all that jazz that you know. Make the mac side work, which it seems we've all been able to do no issues. I used SuperDuper! It worked just fine. (Had it on a disk. I assume you could use any other free way of doing this.)
2) New hard drive running, I used bootcamp assistant to partition the new drive for a new Bootcamp. I don't know if it's necessary to make the new partition this way for some reason, but it's what the process ultimately included, so maybe try without, but it worked with.
3) Natively running original drive on the windows side. Used DirveImage XML to clone windows partition onto new drive connected externally.
4) Back on new hard drive running natively. (Sorry for all the switching.) You'll note that the new Bootcamp partition is NOT bootable at this point. It won't come up in the usual 'alt on startup' boot menu.
Download rEFInd and install on mac side. Technically this is freeware or w/e, but for the love of god, throw money at this man. He totally deserves it.
5) Restarting the computer, rEFInd's boot manager finally recognizes windows. But you'll find windows is a little messed up and still won't quite boot. Get out your Windows CD and pop it in. Do the 'alt boot' thing. Your boot menu options are now "EFI Manager," "Bootcamp," and "Windows Disk." Or some such. Holy Crap! It recognizes Windows!
6) Boot to the CD and tell it to repair the windows volume. It will. My computer also had to do a disk check next time I booted to Windows, which took for-stupid-ever, but eventually worked. (I went to bed in between.)
7) Everything is running smoothly. Plus, you get the rEFInd boot manager, which is also great.

When in Windows 7 (using bootcamp obviously) I am able to see my files in my Mac partition. When I try to access them I am told that I need permission from the administrator. How do I give myself permission to access files between the two partitions?

When in Windows 7 (while using bootcamp) I am able to see my personal files in my Mac partition. When I try to access them I am denied access, it tells me that I need permission from the administrator. How do I give myself permission to access files between the two partitions, Mac/Windows7?

Disk utility resize mac partition resulted in 'no bootable disk' while starting from bootcamp windows partition

my macbook air had two partitions for Mac OS and Windows XP. Because XP partition is too small, I used disk utitility in Mac OS to shrink the Mac partition, and make a new FAT32 partition, which I expected to use it in windows. Till now, I can find three partitions in disk utitily, MacOS/FAT32(which is totally free)/Bootcamp(windows). And in system preference->boot disk, I can see both Mac OS X and Bootcamp Windows.
But when I reboot the computer and press "option" key while rebooting, I only see two boot device options, "mac os" and "recovery", no Bootcamp Windows.
Anybody can give me a hand to recover my previous windows and use the freed partition in windows? Thanks.

Hi Stefan!
I have a rather similar problem having a BootCamp Windows 8 Partition. I actually have 2 NTFS partitions for windows and 1 for Mac OS. The situation is:
0 - for Mac OS
1 - BootCamp windows (NTFS - boot) - 60GB
2 - Windows (NTFS) - 100GB
After updating to Maverick I have no idea why, but now I have:
in Mac OS:
0 - Mac OS
1 - BootCamp - 160G
In Windows:
0 - Mac OS
1 - BootCamp - 60GB
I have tried recovering the partition with a windows program, but all it could do is find it, but without any files on it.
How can I restore my partition table to the way it was?!
WHY did Mac OS mess up my windows partition table?
WHY didn't I get a warning that the Boot Table will get altered?!
Thank you for any help

Increase Mac partition after shrink Windows bootcamp partition

I have a Mid 2010 Macbook Pro running Mac OS X 10.9.4 with a 500GB HD.
The HD is partitioned with 370 GB to Mac and 128 GB to Windows and I decided to shrink the Windows partition to 65 GB because I needed more space on Mac, and I barely use Windows.
I resized the Windows Partition using Mini Tool Partition Wizard and moved it to the end of the disk, leaving the empty right after Mac partition.
I'm able to boot Windows partition and use it normally. The Windows C: disk now has 65 GB.
When I boot on Mac OS X and try to use disk utility to increase the Mac partition, it says that the Windows partition still has 128 GB.
It is possible to use the empty space I created?

I cant access my mac partition in windows 8 Bootcamp

I have a 2012 MacBook Pro with windows 8 installed in Bootcamp 5. I can not access my mac partition. The apple hfs drivers are installed from bootcamp tools. I can not mount the mac partition via disk utility. option grayed out
I dont need to write to the partition so paying for 3rd party software is out of the question
I was filevult encrypted but I disabled it and let it decrypt itself (I now use encrypted disk images)

Easiest Way to Migrate Windows Files on Bootcamp Partition to Mac Partition On The Same Computer)

I have Windows 7 on a Bootcamp Partition on my MacBook Pro. I want to start using Mac OS Mountain Lion full time now and erase the Bootcamp Partition.
I was going to use the Migration Assistant to move my Windows files (such as bookmarks, email, my enormous iTunes Library etc) over to the Mac partition but the problem is that Migration Assistant must be running on the Windows partition at the same time. Difficult to do when they're both on the same hard drive/computer.
I know i could just copy all the files i need onto an external drive but I'm afraid i'll miss something. Plus its alot of work. I'm thinking there must be an easier, mostly pain free way of making the move to MacOS permanently. I can't think of what it would be though. Any suggestions?

Yes, you can simply install the existing drives in the new computer's drive bays. Order is not relevant.
I don't see any reason why Windows will not boot on the new computer from the existing drive. If Windows considers that the hardware has changed all that's required is re-activation. As far as hardware interfaces all you need do is to install the Windows drivers from the installation DVD that comes with the new computer.
Snow Leopard will have to be installed on your existing hard drive, and it must be either a later build or later version than what is shipped with the new computer. Otherwise you will have to reinstall Snow on your existing drive using the installer DVD that comes with the new computer. SL by default does an Archive and Install so your drive is not erased when you reinstall OS X.
If you actually have software that ties its registration to some unique hardware ID, then all you need do is re-enter the serial number. Apple's software does not usually connect the serial number to the hardware, so I doubt you will have any problem with it.
