Windows 7 partition disappeared?

So as I was creating a partition for Windows 7 (500 GB, leaving the Mac partition with 100 GB to spare), it gave me some sort of error about files and what-not (I apologize for not remembering). I then proceeded to click okay, and I tried to create a new partition with the same GB space, but this time, as I was using safari, my iMac froze and I decided to turn off the computer and turn it back on again. After that I immediately went back to bootcamp, and tried to make another partition, but this time, I only had 77 GB to add to the already 20 GB Windows 7 partition. Meaning I only have 97 GB left on my iMac. Did my partition disappear with all that storage? Please help me.
iMac version 10.6.8

That program, NTFS 3G, has nothing to do with whether or not you have a Win 7 partition and whether or not it is still on your drive or has disappeared.
Open System Preferences and go to Startup Disk. Is the Win 7 partition listed as a startup drive? If it is then it hasn't disappeared, it still there. Another way to get to it is to hold down the Option/Alt key at startup. That brings up a BOOT Menu screen where you can select which partition to boot from. Is the Win 7 partition listed? If it is then it hasn't disappeared.
But that program you installed has been corrupted in some way and not loading. That program, NTFS 3G, is for Mac OS X to Write to NTFS formatted partitions which natively it Can't Do.

Windows partition disappearing - twice

Is this a common problem?
I installed a Bootcamp partition and put Windows XP on it. No problem installing and using Windows for many months. Then one day, it just disappeared - the Windows disk no longer appeared on the desktop and the option to boot from it disappeared from the startup disk in settings. The hard disk space occupied by Windows still seemed to be there i.e. it wasn't available in Finder. So, I used Bootcamp assistant to delete the Windows partition and started again, re-installed Windows XP and thought I'd sorted it until today when I tried to restart the Mac in Windows but the Mac didn't like it for some reason and hung. A quick switch off/on and the Mac restarted in Mac OS and again the Windows partition disappeared although the space it occupied is still there.
Does this make sense?
Is there anything else I can do before I go through the whole Bootcamp/Installation process again?
Should I give up on Bootcamp and use Parallels instead?
Thanks for any help.

I went to boot into windows Xp last night, I use the option key, and it was missing too. Just my Mac HD showing up. Is it related to SL 10.6.6? Can't think of any other changes. Is there any way that my files have not been erased forever?

New Mac, Windows Partition Disappears

I just transferred all of my data from my Intel iMac to my new MacBook Pro by a firewire cable, and everything went off without a hitch except for one thing. I had a 30 GB Windows partition on my Mac, and when I click the alias for it now, it asks for an alias fix. Does anyone know the solution to this? Thanks!

Myself and many others have the same problem - check out this thread

Windows Partition disappeared

Okay, so here's what's going on, I installed windows 7 from my install disk. Something must have gone wrong somewhere because my partition was unable to detect any USB drives, and was unable to connect to any networks ( wireless, so no wifi). So there was no way to install any drivers manually. Because of this I decided it would be best to start over. I went into Boot camp, and I started uninstalling the partition. Part way through it stopped the process and told me that it was 'unable' to uninstall the partition. The moment I press the cancel button, my Windows partition becomes invisible. It is undetectable by any application ( Nor Boot camp or disk utility can detect it). I know it still exists though because every time I check my total disk space ( About this Mac> More Info> Storage) I see that my Apple partition contains 350 gigs of my total 1 tb of hard drive space. It is unable to detect where the other 650 gigs are stored though. I don't know what to do now. Should I wipe my drive, in which case how do I wipe the full drive instead of just my mac drive? I do have all of my mac files in a backup on a hard disk, however I want to be able to delete my hard drive data ( that is ANYTHING on my full tb of hd space) without deleting the Mac OSX 10 that came with the computer.
I'm using the new Mac Book Pro, 15", Retina with 2.6 GHz Quad core intel, 16 gigs of memory. It's the newest edition of Mac Book pro.
What do I do?

Well I've convinced myself that Leopard can happily mount NTFS volumes, so that means that we have to figure out why yours is not mounting.
A variant of nerowolfe's suggestion would be to use the chkdsk utility in Windows. Go to the command prompt (Start\All Programs\Accessories\Command Prompt).
Optional: type
chkdsk
This will take some time and will tell you if your Windows partition has errors, but it won't try to fix them. If it has errors, or if you skipped the first step, type
chkdsk /f
exit
and reboot. After the standard lengthy bootup, Windows will suddenly realize that it was supposed to check your disk and fix any errors. (Why it couldn't just do that to begin with, I have no idea.) This can take a while, even if it didn't in the command prompt. At one point, I was doing this and I thought my computer had frozen during stage 2, but I waited a little longer and it finally updated to 1% complete. Eventually it will finish and then reboot itself. Hopefully that will solve your problem.
Alternatively, if you are currently in Mac OS and are motivated, you could try some Terminal commands. For example,
diskutil info /dev/disk0s3
or even
sudo mkdir /Volumes/Untitled
sudo mount -r -t ntfs /dev/disk0s3 /Volumes/Untitled
If either fails, then the resulting error messages may prove useful. Also, if the latter fails, but does not seem to provide a useful error message, then perhaps
sudo mount -d -v -r -t ntfs /dev/disk0s3 /Volumes/Untitled
will provide some useful diagnostic messages.
I'm not sure why the sudo mkdir is needed, but unfortunately it is. It doesn't seem to do any harm.

Windows partition disappeared says locked

Hello everyone
I'm having an issue with my Mid-2012 Non-Retina MBP. I'd installed Win8 through Bootcamp on a 40GB partition and everything was fine until I hadn't used it for a couple of months and it no longer showed up in the boot options. I inserted my Win8 disc to attempt a repair the partition, and Windows 8 told me it was locked. It shows up in OSX disc utility and shows no error when I do a repair. Anyone have any leads on what might be going on?

Will installing OS X Lion stuff up my windows partition?

Thinking of upgrading to lion but worried it could cause porblems with my windows partition.. Wondering if apple have fixed up these issues yet?

I Have a windows partition as well as a ubuntu partition. When I installed ubuntu, the same thing happened that a lot of people are describing. My windows partition disappeared, but my system files were still there. This was because once anything messes with the existing partitions, the built in boot manager no longer recognizes your partitions. I have a boot manager (rEFInd) that I installed that I use to recognize and boot all my partitions now. Now I want to update the OSX partition and it's giving me warnings that this will negate the bootcamp boot manager (which is why I have rEFInd in the first place), and I just want a way to bypass the warning

The disk space disappears after bootcamp failed in deleting the windows partition.

Hardware: Macbook Pro 700
OS: Lion v10.7
1. I installed Windows 7 in my mac. The space of Windows partition is 80G.
2. Some dlls of Windows will always disappear and at last the Windows cannot be started successfully.
3. Yesterday I updated Lion and started the bootcamp to remove the Windows partition. But bootcamp throwed an error(I forget what the error is).
4. I started bootcamp again to try to remove the Windows partition, but there is only create Windows partition in the options.
5. I started the Disk Utilities and verified the disk. The reported result was that there were some errors in disk.
6. So I restarted the machine and pressed COMMAND+R and entered the Disk Utilities to repair the disk.
7. After repairing the disk, there are no errors in disk now. But 80G space disappears.
Now my whole disk is still 320G, but the mac partition is 238G.
How can I repair it? Please help me.
Some logs in system:
Mar 8 04:54:44 ko-hitoshimatoMacBook-Pro com.apple.kextd[10]: Error reconsidering volume /Volumes/BOOTCAMP.
Mar 8 04:57:25 ko-hitoshimatoMacBook-Pro fseventsd[18]: log dir: /Volumes/BOOTCAMP/.fseventsd getting new uuid: 399DDE3E-37D7-43A8-8BD1-049EF76C803F

Figured it out myself! I didn't have any ports open on my MBP for LAN access....

Bootcamp Windows 7 Disappeared after partition resize

Hello guys,
I have a Mid 2013 Macbook Pro 15 and just recently I installed windows 7 using Bootcamp. After a few days I decided to resize my Windows partition.
So, I used Disk Utility to shrink my OSX partition. Then I restarted my laptop in Windows 7 and used a third-party software to add the available space that I just created to my Windows partition. After finishing the operation and restarting my computer in Windows everything was fine. (The disk has been resized and no files were missing whatsoever). Few hours later I wanted to use my OSX, so I restarted my laptop in OSX again and BOOM. Bootcamp disappeared. When I was opening "Startup Disk" nothing was there, like it has been completely removed.
I've done a little research but I couldn't get any results with terminal commands and stuff like that.
So what I did is this,
I restarted my computed holding the options "alt" key and got into the Startup Manager.
There were 3 Drives
1. Macintosh HD
2. Recovery 10.8
3. Windows
I clicked windows and successfully managed to get into my Windows 7. No files were missing everything was working perfectly.
After restarting to OSX again still everything was missing!
So the problem seems to be that Windows are still there and working properly but BOOTCAMP and Windows have disappeared and going in Startup Manager is the only way to access them.
I hope I helped someone with the same problem.
Any ideas or solutions are welcome.

Updated Mavericks, Windows partition has disappeared

Hello, I just updated to the latest version of Mavericks and my Windows partition has disappeared. Can anyone help me get it back, or is it gone?

Hi Eric, I have tried that and its not there. Also when I try to reinstall windows in bootcamp it says that I need to uninstall windows first which it then says it cant do... any suggestions? Im hoping someone will have a miracle cure to make it all come back!!

Updated software on Macbook Air and bootcamp partition disappeared. Windows boot option no longer appears. Can I get it back and the data?

Updated software on Macbook Air and bootcamp partition disappeared. Windows boot option no longer appears. Can I get it back and the data?

Amy, is there a chance they could both be Syncing to another device that has the data erased?
What are the sizes & modification dates on the files you found?
Could be many things, we should start with this to be safe, though 2 different ones would seem unlikely to be this problem...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

Can't Mount Windows Partition in OSX After Upgrading to 10.5 and BC 2.0

I just installed Leopard today, using the upgrade option (as opposed to a clean install). I was happy to see that I could boot into Windows still, and installed all of the Boot Camp 2.0 drivers while booted into Vista. However, I can no longer mount my Windows partition in OSX. While using Tiger, I did use MacFuse and ntfs-3g to get read-write support, but in Leopard, I can't even read. When I try to mount the Windows volume in Disk Utility, I get an error stating that it cannot be mounted. I also do not have the option to perform "First Aid" or "Repair" on the volume.
I realize that the latest version of ntfs-3g isn't proven to work with Leopard, but I would at least like read access in OSX. Is it possible that some settings were left over from my Tiger configuration that would not allow Leopard to mount the partition? Any ideas?
Thank you.

Ok. I'm in the club with the same problem...
Strange things:
* For the first days after Leopard's install, my BootCamp disk0s3 partition (I'll name it "BillGates") was mounted correctly. Then, after a few days (but BEFORE upgrading to 10.5.1), it disappeared.
* If I launch DiskUtility "BillGates" is shown, but (in the right device navigation bar) it's named "-n BillGates". If I click the Erase menu, it's named "-nBillGates" (without the space between "-n" and "BillGates"). If I launch SystemProfiler it's named "-n BillGates", but the mount point is "/Volumes/billgates". Can't understand where this "-n" thing is coming from!
* If I try to mount "-n BillGates" from DiskUtility it doesn't work and the log says "Mount of -n BillGates failed".
* In the FSTAB there were no instructions: it was empty.
Now, I tried the MacFUSE-solution: no results (meaning BillGates was not mounted on startup).
I tried the modify-the-FSTAB-solution: no results (with "BillGates", "-n BillGates" nor "-nBillGates".
I tried the chkdsk-solution: all tests were ok, but nothing happened.
The only trick that worked was mounting the partition with Terminal's commands (thanks rtracy!!). It made appear "BillGates" on the desktop (without the "-n thing", that is still present in DiskUtility).
Problem is at the first reboot, the Boot Camp partition disappears again. Any ideas for a permanent fix?!
Giangiacomo.
ADDENDUM: I've tried to move a file from desktop to an unlocked folder in BillGates and System did not copy them. "The item could not be moved because "BillGates" cannot be modified" !!!!!!!!

IMac 27" (late 2011), Mountain Lion, Bootcamp, and OSX partition disappearing and refusing to mount

Hey all,
I'm putting this as a question in the discussion forms for bootcamp as I'm not sure where else to put it, but I resolved an issue I was having and having spent all of yesterday and the day before reading through this community and some others looking for answers and mostly seeing "hope you have backups, time to format!" (which to me is not always the best answer), I thought I would put it here for search purposes (with all the key words I had to use) in case anyone else has a similar issue.
My scenario was this:
2011 27" iMac with Mountain Lion installed and Windows 7 installed on a boot camp partition.
1) Haven't been in windows in a while, wanted to play some windows only steam games. Load windows 7. All is well. Have fun. Time to reboot into osx.
2) Reboot using bootcamp toolbar icon.
3) Wander away from computer. Come back to find windows 7 has loaded again. "That's weird", I think. Reboot again, this time hold down option key to select boot device.
4) Discover the only options are the Bootcamp partition and the Recovery partition. OSX "Macintosh HD" partition has disappeared. Huh.
5) Load recovery partition and load disk utility.
6) Review disk utility to discover the Macintosh HD partition shows up in the list, but won't mount. Run verify and repair tools. Errors are as follows: Invalid node structure, invalid key length, invalid record count, etc etc. Running a repair fails - disk utility advises me to back up and erase the drive and that the partition is unrepairable. No offense disk utility, but I think I'll try a few more options first.
7) Purchase DiskWarrior on advice of multiple posters in other threads and general online consensus of it being capable of fixing these sorts of errors. Go through process of loading bootable dvd.
8) Diskwarrior cannot see the Macintosh HD partition. This is bad. Review more threads. Advice is that if diskwarrior can't fix it, hope you have backups and wipe the drive. Likely to be hardware failure. I'm skeptical of hardware failure, because windows is chugging along running fine if I boot into it, and I ran a scan of the windows partition and it came back clean. SMART status is also showing the drive is ok. However, running out of options and starting to lose hope.
9) Follow advice in this support topic: http://support.apple.com/kb/ts1417?viewlocale=de_de Both safe mode and disk utility aren't options (safe mode won't work without it seeing the partition) so sounds like fsck is the final option.
10) Start up in Single User Mode (http://support.apple.com/kb/HT1492). Run fsck per instructions. It reports back ok.
11) Realize fsck is checking the recovery partition, and not my damaged OSX partition. Realize I don't know anything about unix commands and have no idea how to tell fsck to check a different partition.
12) Learn that I need to find out what the drive id is for the damaged partition. Reboot, load up disk utility, select greyed out "macintosh HD" partition, click info. Write down the id: disk0s2 (likely to be the default for you as well if you have one drive in your imac and a default bootcamp install).
13) Go back into single user mode and type the following (without quotes): "fsck_hfs -fy /dev/disk0s2"
14) (Forgot to copy down exactly what it said at this point, but gist of it was that the drive had errors and isnt repairable). Feel like ****, thinking this is unlikely to resolve itself nicely.
15) With nothing to lose, try to force fsck to rebuild the catalog - "fsck_hfs -rc -d /dev/disk0s2" I found this syntax on some forums and can't find the thread again. I have no idea what the -rc and -d do that -fy don't, but if someone can let me know, that'd be cool. Either way, this resulted in something actually happening. Tells me it is "rebuilding catalogue b-tree". Still, finishes with a bunch of errors about improperly linked files, more node errors, etc etc.
16) Retry "fsck_hfs -fy /dev/disk0s2". It seems to be doing stuff now, even though there are lots of errors. Continue to re-run fsck using this syntax. Probably ran it 10-15 times. Takes over an hour. Finally, minimal errors being reported.
17) Realize that perhaps I should try Diskwarrior again now, since I've managed to do soemthing to the partition with fsck.
18) Run Diskwarrior from bootable DVD. Success! It now sees the damaged partition. Reports that it has a bunch of damaged crtitical files, and needs to be repaired, but hey, at least it can see it.
19) Let Diskwarrior do its thing, and reboot.
20) Boot from repaired OSX partition. Rejoice. Immediately plug back in the timemachine drive you foolishly unplugged to take away over the holidays and neglected to plug back in before you had commenced work on stuff you didnt want to lose through formatting, which is why you are so desperate to recover files rather than wiping and restoring from time machine backups and avoiding this whole mess.
TL;DR - If Disk Utility and DriveWarrior fail you, try running fsck (using different syntax that apple recommends) as many times as it takes to get the partition to a stage where diskwarrior can see it. All advice I saw for similar questions was to erase, reinstall OSX, and restore from time machine backup. For those of you who are foolish like me and had files that werent time machine'd, or those who operate without, maybe try this.
Hope this helps!

What -rc & -d do.
From: The fsck_hfs manual page.
https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages /man8/fsck_hfs.8.html
-d      Display debugging information. This option may provide useful information when fsck_hfs cannot repair a damaged file system.
-r      Rebuild the catalog btree. This is synonymous with -Rc.
-R flags Rebuilds the requested btree. The following flags are supported:
                         a       Attribute btree
                         c       Catalog btree
                         e       Extents overflow btree
I had the same problem as you but unfortunately "fsck_hfs -rc -d /dev/disk0s2" is failing saying: "The volume   could not be verified completely." I believe it's supposed to be telling me the partition's name (normally "Macintosh HD") between 'volume' and 'could' because there's 3 spaces in between the words.
"fsck_hfs -fy /dev/disk0s2" is failing with the same error.
I tried "fsck_hfs -r -d /dev/disk0s2" since the c appears redundant with a lowercase R. and it again says it cannot be verified completely and adds "volume check failed with error 7". Which unfortunately is not documented on the fsck_hfs man page!
Unfortunately for me, Diskwarrior still can't see my busted Mac OS partition.

Target Disc Mode and only showing the windows partition:

Hi, two weeks ago I purchased Aperture 2 for my MacBook Pro, and during the install, it stated that the install had failed and then froze. I did a hard-shutdown, and when I attempted to boot it back up, it kept trying to boot in Windows-- (It is running Bootcamp Beta/ it's a first generation MBP.) Windows wouldn't even boot up. Repair disc failed, as did numerous other courses of action. Apple advised me of TDM and we verified holding "T" that it would boot up in such. I then decided it was time to acquire a new desktop, which is how I get the Mac Pro. So I'm desperately trying to salvage the data from my MBP, but when booting up in TDM, only the Windows partition appears in Finder...any ideas? It's like the Mac partition has disappeared, as it only appears in the disc profiler thingy that you may access with the OS X disc in the optical drive.
Thanks in advance.

Try using Disk Warrior.
Pull the drive and put it in FW case.

Windows 7 disappear from bootcamp after maverick installation

Windows 7 disappear from bootcamp after maverick installation. What should I do to recover?
I did try co reinstall windows but it make the installation new (nothing remain from the previous). Old windows partition seems lost.

Hi Jack.........ok ive managed to create a link to that video on how to install bootcamp.....this is the tutorial i used and i managed to gain 100% completion on bootcamp 1st time no messing......like i said in my previous reply did you save the windows support files from apple....(Critical).....ok no point in messing about i suggest you start again from scratch........these are the things i used and YOU will need to complete bootcamp
mem stick or cd-r / dvd-r......original copy disc of win 7 ...i never used an iso i used original disc....allow a minimum of 30gb of space for your win 7 partition.....if you want bootcamp so you can use big programs like windows based games i.e.....Crysis/Call of duty etc etc ..then you will need to consider that you will need to allow a bigger partition to allow your HD to store the files.....this is the reason i installed bootcamp and so i made my partition i have a 750GB HD so i made a partition of 300gb for windows 7 and left the other 450gb for Mac....so you need to partition enough for what you want bootcamp for remember once you get bootcamp working you will need to install ALL Important Windows updates Including Win 7 SP1......once everything is installed you will have bootcamp up and running lovely.....u can then boot up with either win7 or mac......click this link and watch carefully and do exactly as shown ok and you should be fine...if you have any probs contact me again ok.....let me know how you get on ok..:)...http://www.youtube.com/watch?feature=fvwp&v=QFIWtXTl4d0&NR=1

I have fix it! Have been reading older post by Loner T all day yesterday!
In case others have similar issue: You should read this discussion where elikeness has concluded what Loner T have told.
Bootcamp partition has disappeared after upgrade to Yosemite 10.10
For me, I did quick search (test disk) on /dev/disk0
and I found a partition that store all my window files.
So I use that partition start/end sector to config GPT and MBR.
After reboot, check in disk util that the partition is mounted and detect as bootcamp.
Check hex dump for R.NTFS string.
Reboot again with "option" button down and boot window
Thanks Loner T for all the help!
You must be exhaust with this issue.
Hope Apple give out a new patch with this fix or automatic quick fix solution.

Windows 7 partition disappeared?
