Boot Camp Corrupted after 10.7.1 update
Win7 was running fine before I updated my 2011 mini from 10.7 to 10.7.1... now Lion doesn't even see the Boot Camp Partition as a bootable drive. So, it must be corrupted. Do I have to reinstall Windows for the 3rd time? Any solutions?
I figured it out! It was NOT the 10.7.1 update that killed Boot Camp! You know that one little thing you did and forgot about.... I loaded Paragon NTFS for Mac. Big Mistake. I went into System Prefs and disabled it. VOILA, Boot Camp majically shows up as a boot drive again. And Paragon says its Lion compatible, HA!

HT5639 how do you uninstall boot camp partion after a failed install of windows 7
I cannot remove a boot camp partition after a failed attempt to install windows 7 64 bit
IS there an option to remove Windows in Bootcamp Assistant?

i have macbook pro 13.3 inch. I am installing window 7 in boot camp manager after copying file of window upto 67% it doesn't response and i had forcely shotdown my macbook. Now my macbook doesn't open and stop in black screen with cursor blinking. Now how could i open my macbook pro.
At startup hold down the Option/Alt key and from the screen that comes up select your OS X partition to start the computer from. Then use the Boot Camp Assistant app to Remove Windows and the partition you reated for it and it will Automatically place the space you allocated for the Windows install back into the OS X partition.
NOTE:
Do NOT use Disk Utility to erase the partition that was created for the Windows install. Use the Boot Camp Assistant app again to do that. -
On my iMAC using Mountain Lion v. 10.8.3, is there a way to increase the size of my Boot Camp Partition after I installed Windows 8? Thanks.
Yes, purchase Paragon Camp Tune for the job.

Have you seen this type of problem before? I think it could be a serious issue for anyone in a similar position.
No; but then, I've not had occasion to use TDM. I've been using firerwire drives for over 10 years, both FW400 and FW800, with no issues except a bit of instability using a B&W G3 machine.
TDM should be safe. Using cautious, manual copying of files from the Target machine to the Host machine should not result in unexpected loss of files or damage to the Target drive's directories. It should behave exactly the same as if it were an external (to the Host) firewire drive.
• I don't suppose there is anything I can do to 'put back' lost items from a separate Time Machine drive which has an up to date backup on it.
There is probably a way to do that - seems to me that's one of the reasons for a Time Machine volume.
On the other hand, if the Time Machine volume is rigidly linked to the now-absent OS on the original drive, there may be no way to effectively access the files in the TM archive.
I know that using a cloned drive would work well in this instance.
I have no experience with Time Machine, so perhaps someone who has will chime in with suggestions.
With the machine in TDM with the other machine, have you tried running Disk Utility to see if you can effect repairs to the drive? -
i was installing windows 8 on mac by boot camp and after i put the windows code and choose the partition i formatted the boot camp sector it said windows can not install on this sector because it is gpt
Reinstalling Mavericks depends on several factors:
if you erased your recovery partition
what OS originally came on your Mac.
I'll assume you don't have a backup available that you made before your mishap, because you didn't mention it.
That's really the take home message here: have a backup!
If you still have your recovery partition:
boot into the recovery partition (command R at restart)
use the recovery partition to reinstall Mavericks. see: OS X: About OS X Recovery
if you do not still have your recovery partition, then it depends on whether your Mac originally came with installer disks or not.
If it originally came with installer disks, you would boot from the installer disks, erase your HD, and then reinstall the OS that is on the installer disks, and then upgrade as necessary until you get to Mavericks.
If your mac did not originally come with installer disks, but you managed to erase your recovery partition, then you can try to boot into internet recovery (option-command-R at restart), and use internet recovery to erase your HD and reinstall the OS that originally came with your computer, and then upgrade to Mavericks if you need to. See: Hands on with Mountain Lion's OS X Recovery and Internet Recovery | Macworld
(the reference refers to ML but it applies just as well to Mavericks). -

how do you enlarge boot camp partition after windows is installed
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 -

Unable to boot Mac OS after 10.6.5 update
Just a question. Dont know whether its due to the 10.6.5 update. After reboot to windows. I can't log in To my Mac os anymore. It just get stuck at the grey apple logo and bar comes out and loads and it shuts down soon after. In windows when I log on it says that my Mac hdd is corrupted. Mount anyway or cancel.
Anyway my question is can I reformat my Mac hdd and reinstall SL without interfering with my windows partition (boot camp)Use the Archive and Install, Mac OS X: About the Archive and Install feature, option to reinstall SL. This saves your Home folder. Also it saves your old Home/Library folder in a "Previous System" folder in case there are any preferences or support files of applications that require activation codes or S/Ns.
Repair disk permissions after the reinstall. Then apply the latest SL updater and repair permissions again.
After you're satisfied all is well you can delete that previous folder.

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.

Boot camp lost after upgrading to Yosemite from mountain lion
I lost my windows7 boot camp after I upgrade to Yosemite from mountain lion. When I press ALT when rebooting there is no more alternative to boot for window anymore. I did read some thread about this but my case is different since when I tried to type 3 steps(diskutil.......etc) as LonerT user answers it did not work. The attached files here are what I faced with. Please help. I have a lot of important files in windows
If you look at the GAP between GPT3 and GPT4 it is start/size of 782929176/37595880 but the NTFS header starts at 782929920 according to your Testdisk output shown here.
MS Data 782929920 976773112 193843193
The difference is 782929920 - 782929176 = 744 bytes. You will need to delete the current GPT4 and recreate a new GPT4. Please stop if you see any error messages and post here.
1. Delete the old entry and create a new entry at GPT#4.

2. This is a tedious process and you want to check after the second 'p'rint command that it looks reasonable, before the 'w'rite and 'y'es to confirm.
3. You will need to reboot after the change, because the disk you are booted from is the one being modified. Reboot will rebuild disk0s4 using the start/end you entered.
4. Run the dd command - sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C and check that the first line contains "R.NTFS".
5. Once you have a working GPT#4, a new hybrid MBR needs to be created which will overwrite what you see in your Fdisk output. This is also done using GPT Fdisk (Gdisk). Your numbers will look different than what are in the following example. In most cases, you will use the default except entry 4, which should have a 'y' for bootable flag.

Boot Camp broken after Yosemite Upgrade
Hi.
After upgrading my 2012 rMBP to Yosemite, my boot camp with Windows 7 stopped working. Specifically:
- I could not see the Windows partition when holding down the alt/option key at startup
- I could not see an option to startup with Windows in the boot camp assistant
- I could not see the boot camp partition in disk utility: all I could see was a partition "disk0s4"
- there appeared to be some unallocated space in disk utility between the Macintosh HD and disk0s4 partitions.
After searching the Apple Support forum I followed the advice posted by Loner T. In summary I confirm the following actions solved my problem:
- running Test Disk, and confirmed that in my case I had not lost data, and that the "MS data" partitions were still there albeit they were marked as "deleted". I used the "Analyse" option to list candidate partitions, and then the "p" option to list the files in the candidate partitions. In my case there was only one candidate "MS data" deleted partition where I could successfully list the files which I could recognise as being from my Windows file system.
- from Test Disk, writing down the start and end sectors of my Windows partition
- running Gdisk, and following the instructions posted by Loner T to
1) replace the bad partition information, which required my start and end sectors I had written down from Test Disk, and (following reboot)
2) replace the MBR information which set my boot camp partition as bootable.
I'm not overly tech savvy myself but was able to follow the instructions posted. I can't offer any further advice myself other than to say it worked for my problem and that I recommend reading the posts from Loner T to diagnose your problem and hopefully fix it.

Will Boot Camp function after upgrade to Mavericks?
Planning on upgrading from Snow Leopard 10.6.8 to Mavericks.
I now have Windows XP on my Boot Camp partition. I also use an old version (2.0.8) of VMware Fusion to access the same BootCamp WinXP. I rarely use Windows & I know my old version of VMware will not work. Would need to purchase a new version (6.x) for ~ $60.00.
But, I’m hoping I could still Option Boot into my BootCamp Windows.
Am I correct? Or after upgrading to Mavericks, will I be unable to boot into Windows w/o a bunch of fixes & troubleshooting?
Regards,
SteveThanks!
Fingers crossed.
As soon as I purchase iBank I will do the upgrade. Will make a bootable clone just b4 I do the upgrade.
Will run Repair Permissions as well.
Probably late tonight or Monday. -
Download Boot Camp again after hard drive upgrade?
This is just a quick question. If I put a new hard drive in my MacBook, will I have to get Boot Camp again, or can I just partition the drive before I reinstall Tiger, and just install Windows with the driver CD I already have from last time? And I suppose I would also like to know if I have to get Leopard in order to get Boot Camp.
You would need Boot Camp and currently it is offered only with Leopard. Not sure if you could install it on a separate non Boot Cam partition and get it to work right.

I have previously installed Boot Camp on this Computer (MBP mid 2012, 15" 2.6 GHZ). I recently replaced the hard drive and was reestablishing bootcamp again. While Boot Camp is writing to the USB thunb drive it crashes and rebootrs. The crash does not generate and message other than a note that there has been an error and the computer is restarting. I have tried several different thumb drives all with the same result. It makes me think that the new hard drive (a Seagate Momentus XT 750GB 7200 rpm unit) does not work with Boot Camp. Does anyone have any thoughts or solutions?
Hi,
I solved the problem myself. This might help others.
Recap:
The Windows XP Pro CD was always ejected by Boot Camp and it wouldn't mount at all when inserted in the CD slot. The CD was however readable on a Windows Machine.
It was not easy to detect but the Windows CD was physically deformed. It wasn't flat. It was a little convex (the outer edge was higher than its center). My iMac wasn't able to read it at all but a PC was able until I decided to test it with a full install on the PC. About half way during the installation, it stopped and an error message was displayed by Windows Setup "Disc Read Error - Disc might be damaged".
I ejected the CD and discovered the deformation. So I carefully placed the outer edge of the CD over a ring and put some weight on its center to try to undo the deformation. I've waited 2 days then retested the CD and it worked at the first attempt. My iMac was happy and so was I. I made a security copy of the CD while it's still readable in case I have to re-install later.
I find Microsoft cheap of putting their Installation CD in a paper sleeve. If the CD have been stored in a CD case this would not have happened.
End of the story.
