Lost Boot Camp partition after failure repatitioning

I was trying to install Windows via Boot Camp, it was failure then I decided to revert changes and repartition the volume (using Boot Camp Assistant), unfortunately it was failure too, I did a hard reset. Now that partition (20 GB) is lost, even in Disk Utility. when I open Boot Camp Assitant there is no "remove boot camp" option.

Further Information:
I haven't resolved the issue yet and still working on it.

Lost Boot Camp partition after upgrading to OS X Mavericks

History:
I had Windows 8 installed on Boot Camp. For some reason I had to enable Bit Locker in Windows that required me to create a partition using Windows Disk Utility. The Windows Disk Utility created the partition but then there was mismatch between GPT and MBR Records.
The system was working as expected.
What Happened:
I decided to upgrade my OS X to the latest version Mavericks 10.9, that owerwritten the MBR Records and updated GPT I guess.
The Windows BootCamp partition disappeared. Only OS I could use is Mac OS X.
Current Situation:
I have been trying many tools so might have further spoiled the situation.

Yes, purchase Paragon Camp Tune for the job.

Welcome to the Apple Support Communities
You can do it with third-party programs, but I don't recommend it because you can damage the hard drive. The best way to do it is to delete your Windows volume and create it again with the size you need

Removing Boot Camp Partition after now using Parallels

Is it possible to completely remove the boot camp partition (under Snow Leopard) without having to reformat the HD and reinstall everything? I don't need it now that I am using Parallels with an XP virtual machine installed on my OSX partition.

utahmac1 wrote:
I ran the assistant and did the restore. Now when my computer turns on I have to hold the option key to get to the mac log in. There isn't the windows boot up option any more. However it wont just boot up to Mac. Any ideas?
Once in OS X go to System Preferences - Startup Volume and set OSX to be the default.
On the next reboot ist should automatically boot into OSX.

Parallel runs slow on Boot Camp partition and other questions...

Hi all,
I have had my MBP santa rosa for about 3 weeks. I love it. Everything is super fast and responsive on this thingy. I have parallel running on Boot Camp partition and it is slow. I mean its not awfully slow but when I click start (the play button of Parallel), I see the spinning beachball for 0.5 to 1 min. When I get to Windows XP or Vista (I tried both of them), there is no way parallel could perform up to "near native" speed, I get a lot of sand-clock and it takes 1 mins or so to boot up MS SQL server 2005. When i tried to open lots of windows at once, it freezes for a while then all the windows pop up. I dedicated 1gb of ram for parallel. I am thinking of removing boot camp and use parallel virtual drive on which to install windows. Would that make the performance any better?
I have another question. I bought Disk Warrior 4 but my lovely cousin broke the disc into half coz he thought it was a cheap toy. Is there anyway I can make another bootable CD for disk warrior? I know BootCD only works on Panther. Can I use SuperDuper to clone my MBP and put the image file on a PC-formated external hard drive to bootup from there to run Disk Warrior?
Thank you so much for your help. I gotta say this MBP is the best laptop I have ever used in my entire life. VEry happy with the purchase so far. Thank you Apple.
MacNo0b
p/s: Any recommendation on how to keep the Mac running well without slowing down? Cheers

I have to say, I have never used Parallels in a system with 2GB. I don't feel that it's worth it given Boot Camp is available. That said, if you run nothing else it should run quite happily.
If you're having problems getting through the installation try setting it up with a virtual environment that has no drive. That way you should be able to get through the installation/setup and then you can add your Boot Camp partition after that.
As for transferring files, I will either use Parallels folder sharing else a 1GB DOS formatted USB flash drive.
PS You're right, I certainly can't complain about the equipment I get to play with. I've had to fork out quite a bit of money for the privilege but it's all been worth it.

I had to replace my iMac due to hard drive and Logicboard failure, so I want to reinstall Windows 7 on a Boot Camp partition. Will there be a problem reactivating Windows 7 Home Premium?

Hi,
should be no problem.
Best case is you can activate online via Internet.
Worst case is you have to call Microsoft and explain that it is the same computer after a mainboard failure.

All files on Boot Camp partition mysteriously erased after 10.5.3 update

My wife's MBP 2.4 was running 10.5.2 with a Boot Camp installation of Windows XP. The other night she upgraded to 10.5.3 and everything on her Boot Camp partition was erased somehow.
She spent most of the day working in Windows. During the day someone gave her a usb key with some photos on it that when she plugged it in to her computer something came up in Turkish (she is presently in Turkey) that her friend said she should just close the window and she did. She shut down and switched over to the 10.5.2 install, repaired permissions, and then ran software update to go to 10.5.3. I believe her Boot Camp is updated to the most recent version on the PC side. After the update completed she went to go back into Windows and could not start up in it. It turned out somehow everything on the Boot Camp partition was gone. The partition name was the same as it had been previously and it shouls as all of the space available. None of the material was in the Trash on the Mac side and she had quite a build up in the Trash folder - so it wasn't put in the Trash and then the Trash emptied. It was as if someone had reformatted the partition.
I would chalk this up to user error when she was in disk utility maybe or someone in her studio screwing around with her computer but the same thing apparently happened to one of her classmates shortly before leaving for Turkey. Anyone heard of this happening or have any thoughts?
I had her saving all data to the Mac partition so luckily no data was lost - we just need to reinstall the programs to the Windows partition.
Thanks!

Nope, that didn't happen. The mbp has been loaded directly with Leopard since release day, and had few problems. I've done all the updates from 10.5.0 without any issues. But it was definitely something in the 10.5.3 update that hosed my video (or just a really, really strange coincidence and/or bad timing).
It's not just an OS driver, either. This is lower level than that, because I get NO video from a complete startup. There's no grey screen with the apple logo-- it stays completely blank. This almost surely means that the low-level firmware got corrupted or flashed incorrectly. The fact that the OS detects it as something completely different (Intel GMA X3100) supports this idea.
Thinking back, I did do the update with my laptop screen closed and using a 20" Apple Cinema Display, which is how I use the laptop 90% of the time. And in each of the previous updates, I'm certain they were installed similarly. I mention this, because someone else mentioned having the same issue as me, and noted that the update was done with an external display. Perhaps the firmware update is bugged so that if it doesn't detect the native display, it gets hosed...
I saw some other suggestions in another thread that sounded interesting. For instance, you can create a self booting CD on another Mac that reflashes the EFI (low level bios) to a factory setting. This could potentially fix it, and I would be willing to try it, if I still had my laptop.
In the future, just because things like this make me paranoid, I'll probably reboot the mbp and use only the native display before I do any updates...

Boot Camp partition not bootable after update

Hi All, hi Loner T!
After an OSX update I lost my Boot Camp partition. Reading you replies here on the forum, i was able to save my important files through testdisk, for what i'm really thankful! Following your instructions in this thread (Bootcamp disk0s4 gone after Yosemite update) the bootcamp partition finally appeared in finder and disk utility.
But sudo gdisk /dev/disk0 returns with this:
Kovacs-Peter-Attilas-MacBook-Pro:~ kovacspeterattila$ Sudo gdisk /dev/disk0
Password:
GPT fdisk (gdisk) version 1.0.0
Warning: Devices opened with shared lock will not have their
partition table automatically reloaded!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Command (? for help):
So if it is able i would avoid reinstalling windows, and all the applications with your help. I saw many people asking you about this case, so i hope you may can help me as well.
Thank you!

Hi LonerT, I too have lost the ability to boot into windows/bootcamp - only Mac & recovery are displayed at startup.
Below are my results for the same set of instructions.
What does it indicate?

After Boot Camp partition, iMac no longer boots

Hi, I have a 20" iMac Core Duo (the first Intel Mac off the line) running Snow Leopard 10.6.4. I ran the Boot Camp Assistant to partition my hard drive, and it successfully created the "BOOTCAMP" drive. When it asked for my installation CD, I tried loading a Windows installation partition through a USB hard drive, but the assistant would not recognize it as an install disk. So, I closed out of the assistant early, leaving the Boot Camp partition in place. Eventually, I rebooted my machine in an attempt to boot directly from the USB drive and resume installation.
However, I found the machine will not boot at all. It powers on normally, makes the startup sound, but after a few seconds I'm left with just a flashing folder and question mark icon. Holding down Option-key at startup does nothing. Trying to boot from my Snow Leopard disc by holding down C or D during startup does nothing. Holding down Command-S does nothing. Holding down Shift-key does nothing. Resetting the PRAM does nothing.
What can I do? Is there some way I can access the on-board EFI to make sure the correct startup disk is selected? Why am I unable to boot from my CD drive?
Thanks for your help, everyone.

On OSX go to System Preferences the Startup Volume and reset your Windows 7 partition to be the default.
On the next reboot it should automatically boot into Windows.
A PRAM-reset http://support.apple.com/kb/HT1895 can be the cause of this behavior.

Windows disc does not update after resizing boot camp partition

When I bought my iMac, it came with a 500 GB HDD. I used bootcamp to make a 200GB windows partition and a 300GB Mac partition. The other day I bought a 250GB SSD, and moved everything from my 300GB Mac partition onto the SSD.
My plan was to use the whole 500GB HDD for windows. So, I deleted the 300GB Mac partition and made it free space on the drive. I then expanded the boot camp partition to take up the whole drive using Mini Tool on windows 7.
Now, windows 7 shows that my drive is 465GB, but when I boot into mac, the bootcamp hard drive still reads 200GB and 300GB are "free space" even though I expanded the drive using Mini Tool.
I tried to fix this by filling up the hard drive with an extra 120 GB so it exceeded the 200GB limit that windows shows. But when I booted back into OSX to see if it had worked, none of the files were showing up in the drive, making me believe that boot camp and OS X are not reading changes I am making to the bootcamp drive when I use Windows.
How can I change this so Disk Utility shows the full size of the disc, like Mini Tool does?
I will try to upload screenshots soon.

Re-sizing Windows partitions is not supported on Bootcamp. It requires a clean install. The other option is using Winclone.

How can a Windows partition be resized after Windows is installed?
You need to delete the Windows partition using the Boot Camp Assistant, and start over to change the size of the Windows partition. Back up your important Windows files first.
