Bootcamp problem cannot format windows partition

I have tried numerous times to run bootcamp to install Windows on new Macbook 13" Retina. It always hangs at the stage where windows tries to format the BOOTCAMP partition. It says it cannot format it
I contacted Apple support who said that I could use disk Utilities to format the Bootcamp partition - no I can't! I have the partition shown in Disk Utility but there is no option to format it. There is an option to erase it with NTFS greyed out and it says in the info that it is in Windows NT file system
Any ideas - I have been trying this for weeks now
I bought Parallels but that was useless - even after giving over most of the 8GB memory to Windows it kep freezing / going slow?
How do I persuade my Windows install disk that the drive - called Untitled - is NTFS and that it can install (Windows 7) on it
Very frustrated as all this worked first time on both my iMacs
Help please

Personally I have had no experience with this problem but maybe these urls will have some useful info.

Upgrading MacBook Pro Hard Drive - cannot get Windows partition to work

Hello,
The other day, I decided to replace my 320 GB hard drive with a 1 TB hard drive/SSD hybrid. I did a little bit of research about cloning the drive before that, and it seemed pretty straight forward to clone the OS X partition, but I wasn't really sure about cloning my Windows partition. Originally, my 320 GB hard drive had 2 partitions: 220 GB for OS X Mavericks, and 100 GB for Windows 8.1.
I bought the new drive with an external enclosure and plugged it in. The first thing I did was open Disk Utility and partitioned the new hard drive (750 GB HFS+, 250 GB NTFS). I figured I would need to partition it first and clone each partition separately. I used Carbon Copy Cloner to clone the OS X partition, and it worked with no problem (I immediately could restart my computer and boot with the partition on the new drive, while it was still plugged in by USB).
Next, I tried using CCC to clone the Windows partition the same way (I realize now that CCC cannot do this). 7 hours later, the cloning was complete, but there was an error that a couple files couldn't be copied. I tried copying them manually but it didn't work. I wasn't sure if the Windows partition would work, so to find out, I switched the hard drives and put the old 320 GB one in the external enclosure. I booted my computer and it booted the new OS X partition with no problem. It also mounted the Windows partition that I cloned with CCC, and I can access all of the files in it. However, when I restarted and held down "option", it would not let me boot the Windows partition.
After some googling, I realized CCC is not able to clone a bootcamp partition and make it bootable, so I opened disk utility and deleted the Windows partition (using the minus button), then recreated it (using the plus button). I downloaded Winclone (paid $30), which supposedly can clone a bootcamp partition. I opened Winclone and it seemed pretty simple: you just choose the source partition on the left, and the target on the right. I plugged in the USB enclosure with my old hard drive, and in the Winclone menu the original Windows partition popped up. I chose that as my source, and chose to copy it to the new NTFS partition on the new drive that I created. I left it on overnight, and when I woke up it said it was completed.
I now had two drives mounted: my NTFS partition that I created, and a new one that said "EFI". I have no idea what EFI is. My NTFS partition looks like it has all of the files from my original Windows partition on it; however, when I restart it does not allow me to boot with it, although I now have the option to boot EFI. When I select EFI, I am given the Windows 8.1 start up screen (with the blue Windows logo), but then an error message pops up saying something like there is an issue and it needs to restart (it restarted before I could read the whole thing).
When I boot in OS X, I only have the NTFS partition (with all my Windows files) mounted, and no EFI. When I restart, I can still boot EFI, but I always get the same message and then it restarts.
Is there any way I can fix my Windows partition so that it works the same way it did on my old drive? What is EFI? Should I delete it? How can I make the NTFS partition, which seems to have all of my files, bootable? I only want 2 partitions: one for OS X, and one for Windows. Also, can I do all of this without having to reinstall either of the operating systems?
Thanks

Hmm, that's a good question!
I headed over to the twocanoes website (the folks that make Winclone) and their guide mentions something about running Sysprep before you create the Windows image. If you skipped that step, that may be why you're having issues
http://www.twocanoes.com/support/winclone/migrating-a-bootcamp-partition-with-wi nclone/
Step 24 in that guide also mentions copying a Boot file - were you able to/did you do that?
You may have better luck over in the Bootcamp forum, which is here.

I cannot access windows partition after an unexpected stutdown

Hello everyone,
while I was working on my windows partition(windows 7 ultimate) in my imac 27' i5, a strong and continuous error sound and black screen appeared without shut down the machine,so I pressed the button( in the back of my monitor which is used to start up my machine).
After that windows partition only starts with safe mode (where so no much I can do),(in normal mode a blue window appears which says something about remove hardware, error and some things which I can not read cause it disappears too quickly (1sec).
So,after several efforts in save mode I understand that there was a problem with an installation of an antivirus program,which had not been installed correctly,and in save mode I got a message of catastrophic failure,and also I can not uninstall or remove this program under safe mode.
Till now I have been advised to delete bootcamp partition,and create it again and run windows again,so do you think this is the only solution?
Is there any way to access bootcamp files and modify under macintosh?
I need to mention that I have imac about two months, and usually I use windows partition (because I work with a program which is not supported by macintosh).
Also, do you think that deleting windows partition and creating again is there any case to harm my mac?
Which edition of windows is better compatible? (If there is one)
iMac, Mac OS X (10.6.4), 27''

Personally I have had no experience with this problem but maybe these urls will have some useful info.

Deleted bootcamp by mistake in windows partition

Hi guys,
I deleted by mistake the bootcamp in the windows partition, while I wanted to install SP3 for Win XP as it is required for a program I need.
Unfortunately I do not have neither my installation DVD for OS Snow Leopard nor for the XP with me.
How do I get the bootcamp back to install the exe-file for the update so that I can install the SP3 for windows???
Thx a lot
cheers
tomasino

I actually deleted the bootcamp program itself, as I was told that there was not enough space on the HD (4MB missing).....and I did not read the latest threads that this is a problem due to missing SP3.
As I wanted to delete the basecamp (for GARMIN) I deleted the bootcamp instead and did not realize it.
But the link you refer to is just for the updates, that I tried already and it did not work as I could not start the BCupdate.exe file.....no idea why not.
I will try to install the 3.1 and then see what happens.
any other ideas?

Cannot access Windows Partition after Disk Utility (Mavericks)

Today my Windows partition worked. So I thought, might as well fix the permissions of the drive and also repair the drive for any bootloader problems. Resulted in an error saying "Live file system repair is not supported".
Mavericks still works boots fine. Windows on the other hand, does not appear when holding down the Alt/Option key at boot.
Please, I don't need an official documentation that teaches me how to install Boot Camp correctly, I just need an experienced answer to explain what is going on, don't post just to get points please.

I have this exact same problem. In my case, I had a Boot Camp partition set up and fully working, with Windows 8.1. Then, using Parallels 8, I set up a new VM to use that Boot Camp partition (following some instructions from Parallels that I found online).
After that, Windows felt that disk repairs were needed, but it never successfully repaired them. So I went to disk utility, selected the whole hard drive (not just a partition), and did repair.
This led to the error from Disk Utility: "Error: Live file system repair is not supported." And after that, when I reboot with the Option key held down, the Windows partition no longer is even shown. I hope like h*ll it isn't gone, because I had spent some time getting things setup on it.
Someone, please help.

Problem removing a window partition

today i installed window xp via boot camp, the installation seems fine all the way up until the step 'to install boot camp drivers'. after i inserted the Max OS X disc, it went thru the normal installation...etc. then towards the end i got the 'Found New Hardware Wizard' window and a second saying boot camp is finished. however, at this point the mouse is dead and i am unable to move it. i rebooted it a couple of times, still the mouse is disable.
so, i boot back to Mac OS, open up Boot camp and decided to remove the window partition. i chose 'If your computer has a single internal disk, click Restore'...
then i am at the 'restore disk to a single volume' with the status: partitioning disk spinning...
when i created the window partition i used 15G and i have the unibody macbook with 250G. however, this window's been spinning for the past two hours. i really don't think this should take this long. is this normal?
i do not want to re-install 10.5.5 and do a restore. what is the best way to delete the window partition? i suspect something is wrong with boot camp. what should i do?

There are few things you need to make sure before you remove the federation, like permissions, TXT records etc.

Cannot mount Windows partition with boot loader on Mac OS 10.8

I took out my hard drive of my Windows 7 PC, which has 3 partitions on it: C drive which contains the OS and the boot loader that the computer boots into, D drive which contains my data, and a third called "System Reserved" a few megabyte in size that I have no idea what so ever what it does besides that I cannot modify or delete it, which probably means that it is important. Now I put the hard drive inside an USB 3.0 enclosure and I am trying to mount this hard drive onto my OS X Lion Macbook air. Something strange is happening, in that the computer takes about 30 seconds or more to detect the drives presence, and then it just freezes after that. On the initial try, the system actually successfully launched DiskUtility, and I can see the drive mounted in the list of detected drives and 3 partitions "SD1, SD2, SD3" under that drive, but after repeating the procedure a few more times, nothing seems to be happening after the system freeze.
Anyone have any idea what's going on? I am trying to access the data partition for my stuff.
I have Tuxera NTFS installed, and I should probably also mention that my Macbook Air is mid 2011 with only USB 2.0 ports.
Thanks in advance.

Ok, I figured out the freezing part; apparently, I had to connect to the USB port on the left side next to the power supply or the disk does not have enough power and causes the system to crash. So, now Disk Utility can see the hard drive with no problem.
But now, the partitions are detected as XFAT format and no volumes are mounted to the desktop. Disk Utility displays the disk description as:
Disk Description : INTEL SS DSA2M160G2GC Media Total Capacity : 160.04 GB (160,041,885,696 Bytes)
Connection Bus : USB Write Status : Read/Write
Connection Type : External S.M.A.R.T. Status : Not Supported
USB Serial Number : CVPO049000W0160AGN Partition Map Scheme : Master Boot Record
Why is the status "not supported"? How should I go about mounting the data volume so I can access the files on my Mac?

Problems booting a Windows partition after failing to install and uninstall NTFS 3G

Hi,
I run Windows on my Mac and I installed MacFuse and NTFS 3g today to see how would they work together. It was a terrible decission...!! After restarting the computer a window popped in the desktop with the following message:
NTFS-3G could not mount /dev/disk0s5
at /Volumes/BOOTCAMP because the following problem occurred:
Did not receive a signal within 15.000000 seconds. Exiting...
Afterwards I uninstalled NTFS 3g from System Panel but had problems uninstalling MacFuse. Curiously, I didn't find any preferences file of any of them. Anyways, I dived in some forums and about diferent ways to tackle this, of which I followed this one by bredikhin:
Link: https://discussions.apple.com/thread/3942492?start=0&tstart=0
This succeeded in unistalling MacFuse, but didn't allow me to boot Windows at the menu you arrive after pressing and holding the option key. Nonetheless, I can read the files in the Bootcamp partition from Mac.
I'm using a MacBook Pro running OSX 10.8.4 on a 2.3Ghz Intel Core i7 processor with 4GB of memory
Thanks in advance!

As has been said, Windows 8.1 isn't formally supported yet, though I have it installed on mine.
Sadly many people have had problems with Bootcamp on Mavericks, especially on later Macs.
Some have had success by creating the bootcamp partition with Bootcam Assistant then rebooting in to OSX and deleting that partition then creating a new exFat partition in its place, named BOOTCAMP.
That partition can then be re-formatted NTFS by the Windows installer which then makes it usable.
Others have been less successful.
If all fails Google can turn up various workarounds until Bootcamp/Mavericks get sorted out (and 8.1 becomes supported).

Cannot exclude Windows partition

I have a FAT32 partition for Windows, and I cannot exclude it from searching by spotlight. The directions clearly say I can drag over a drive or select it in the list, but I cannot add my "XP" drive. I can add the Macintosh HD drive fine.
Why is this? Is it a bug?

I read that quote –
"Spotlight works with most locally mounted volumes that can be read and written to, including FireWire and USB/ flash drives. Some volumes, such as Windows-formatted drives, are not indexed automatically. You can change this easily by opening the Info window for the volume in the Finder."
– but I can see no way (easily or not) to change this in the info window. The only thing changeable there are the volume name and comments. Does anyone know how to get windows formated drives to be indexed from the info window or by any other method?

How Do I Remove Bootcamp and The Entire Windows Partition?

I have Windows running on my iMac with a partition. I want to remove it in its entirety to take the machine back to a 100% mac platform. Any thoughts?

Easily done!
Run BootCamp Assistant.app and restore to a single partition.
As with all these kinds of operations, if you do not have a complete backup of Leopard, you should not do this, or if you do without a backup and "stuff" happens, just remember my post here.

Problem - cannot format hard drive even after replacement

Dead hard drive. I was able to recover part of the data in firewire mode.
Rebooting from OSX disk hangs with a circle slash. Same if I try to reboot with Diskwarrior CD or TTPro. Removing the hard drive has the same result.
Booting from an external firewire utility drive is successful, however I'm unable to successfully reformat the hard drive. Disk Utility sees the drive, and begins to reformat, but hangs at about 10%, and it instantly shows more than 10 partitions but none of them successfully are created. Drive Genius just fails to initialize.
I tried a different hard drive, same result.
Apple Hardware Test and TTpro all show that hardware is OK.
Any ideas?

Hi James,
I'm not clear on some things:
"Rebooting from OSX disk hangs with a circle slash.
Same if I try to reboot with Diskwarrior CD or TTPro.
Removing the hard drive has the same result.
Correct. I cannot boot from ANY bootable CD except AHT, not even with the internal drive completely disconnected.
Booting from an external firewire utility drive is
successful, however I'm unable to successfully
reformat the hard drive. Disk Utility sees the drive,
and begins to reformat, but hangs at about 10%, and

First you say you can't boot with DW or TTP, then you
say AHT and TTP show hardware is OK. So you
can boot with DW and TTP?
I cannot boot from ANY CD. But I CAN boot from an external firewire drive. My iPod is a diagnostic drive, which includes TTP and AHT. Oh, and I CAN boot from an AHT CD but only into AHT, not beyond AHT into the finder.
Are you running an OS on the external HD that's at
least as new as the one that originally shipped on
the PB?
Yes. It's the brand new version of Protogo that just came out in Jan 07. I've also tried CD's from 9.1 to 10.4.
Have you reseated your RAM? Tried with just one
module? Switched that module to the other slot?
Repeated same process with other module?
Yes, that was actually the first thing I tried.
If still no luck, try removing the bottom cover,
gently snugging up all the screws you can find,
flipping the keyboard up and doing the same, then try
booting (with bottom cover off).
If still no luck, I would try the
href="http://www.posner.net/marc/projects/TiBook/TiBoo

If still no luck, sounds like a logic board issue, or
possible the display cables in the hinges.
Tried that too...no change.

Can i format a partition of a windows formatted HD for OS Extended?

things have gotten a little complicated over here but i think i finally have my windows 7 and windows xp installations on my mac pro.
the windows 7 is on my first hard drive in bay 1 "under" Lion via Boot Camp. from everything i have been able to gather we have formatted the second HD in bay 2 as a FAT32 or NTFS and actually installed windows XP right on a 300 GB partition on this drive. i know this sounds a little goofy but my understanding is that we have avoided installing Leopard (or whatever) on this second drive by going straight to the windows installation on this drive.
here is my question.
i just went to backup the data in my Lion OS that is on my drive in bay 1 on the remaining 700 GB in the second partition on the HD in bay 2. however, i cannot do this because this HD is formatted for windows.
does anyone happen to know if i can just format this second /partition/ as a OSX Extended and use this leftover part of the drive as my internal backup of my Lion OS? i mean, i used to use this second HD as a daily internal backup of my Lion OS and i would like to use this space for this if at all possible.
TIA and advance apologies for anything unclear on that.

This is made incredibly complex by Mac OS X use of extensible GUID Partition Map including an EFI partition and (possibly a Recovery_HD partition as well) Vs. Windows insistence that:
1) GUID Partition Map does not exist, and that
2) MBR Partition Map is the only one in existence, and that
3) no drive will EVER need more than four partitions total.
When you use BootCamp to put the Windows partition on a GUID drive (such as the Boot Drive) it adds an additional MBR partition Map to the existing GUID partition map. This allows Windows to boot off the same drive (Windows just reads the MBR partition Map it wants to see and ignores the GUID partition Map). This works UNTIL you use any Windows Utilities to modify partitions, after which Mac OS X becomes unreachable and will not boot properly again until you rebuild them both.
When you use Windows Utilities directly to partition a drive, it becomes a Window-only drive. To have Mac OS X use it as a Boot drive requires GUID partition Map and an EFI partition. Mac OS X needs to get in first, create the GUID Partition map, and then have BootCamp add and correctly maintain the MBR partition Map as well as the GUID partition Map.
Since Linux piggybacks on the Windows booting techniques to get Installed, there are some utilities from the Linux Open Source world, such as REFIt (has EFI in the middle of its name) that are designed to manipulate both maps in concert. They may be worth consideration.

During Windows install, says the Bootcamp Windows partition is incorrect file system and won't install

I had another Macbook Pro retina which I installed Windows 8 on with no problems via bootcamp. I just updated to the late 2013 model of the Macbook Pro, and attempted to do the same thing but have had problems. I create the partition for Windows with Bootcamp, restart the computer, and after I enter my security key in the Windows installation screen it comes to the screen where you have to select the appropriate installation drive. When I select the drive I created for Windows, it says that it can't install due to the file system. I have no idea why I'm having this problem because I had done this once before....I can't for the life of me figure out what's wrong and I'm at a loss.
If anyone can point me in the right direction I will greatly appreciate it...also let me know if there are differences from the early 2013 model and late 2013 model that would've created this problem. Thanks!!

Well, here is what happened...
Somehow in making a Windows partition then removing the partition so many times I created an error where it only showed 1/2 of my hard drive...like it was starting to create the second half for the windows side and ran into an error.
So this turned out to be a blessing in disguise, because what I had to do was go to "Command + R" when I was starting up and format the entire drive, all 500 gb. This formatted the whole drive and must've erased whatever was causing the trouble.
Of course, then I had to reinstall OS X, and reinstall my Time Machine backup, but then I opened bootcamp and created the Windows partition again. This time, when I ran the EFI installer you were referring to on the far right (which I had tried before), it allowed me to click next and continue once I selected the Windows partition. Thank God! It must've fixed whatever file system error was hanging it up there every time....because it's installing now.
What I would suggest if all else fails, just format the whole dang thing. Then try from square one and see if you can install

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.
