Boot Camp Is Unable to Partition My Drive

Hello,
The first time around I managed to set up Boot Camp and Windows 7 Home Basic very successfully and effortlessly on my MBP mid-2012.
Then I found out I could not get activation key for it because Microsoft no longer sold the Basic version. I downloaded the Windows 7 Home Premium version and bought an activation key from Microsoft and am now trying to get it on my computer.
Using Boot Camp Assistant I was able to delete the partition on which old Windows resided. Then using Boot Camp Assistant I built a USB drive that included the new ISO for the Windows 7 Home Premium edition and then the process went well and all necessary support files were downloaded.
We got to the point where I selected the size of the partition and Boot Camp Assistant tried to partition it except that it is not able to. It doesn't giver any reason, it just says: "Your disc could not be partitioned. An error occurred while partitioning the disk."
Anyone here knows what could be the cause of the problem and possibly how I can resolve it?
By the way, I have checked and the base format of the drive is Mac OS Extended (Journaled), and the disk has only one partition.
Thanks much.

I am doing a TM backup now. I looked at the iDefrag and the drive definitely needs defragmenting, according to the software, but I thought with Macs we don't need to worry about those things. I want to do one other thing I read somewhere else as a remedy for this inability to partition the drive before taking the leap and doing the full erase and reinstall.
Here is the link on the internet: http://crounji.wordpress.com/2014/01/28/a-solution-to-your-disk-could-not-be-par titioned-error-on-boot-camp-assistant/.
And I believe another forum has discussed this topic.
Here is another approach I want to try: Boot Camp: Partition alert message when using Boot Camp Assistant

Boot Camp Assistant couldn't partition the drive

Hi everyone,
I recently deleted my windows partition, and wanted to create a new one, however, boot camp assistant told me that I couldn't (I do not know the exact wording). Boot camp assistant said to save my mac drive as an image, reformat my hard drive, and restore the image using disk utility.
SO, I tried to, but something went wrong, because the disc image I have will not mount....
In disk utility, I created an image of Macintosh HD, but I'm thinking I should have created an image of my hard drive "320.07 GB WDC3200..."
Can anyone confirm this?
Also, if anyone knows how I can view the files in my dmg that I created, that would be great.
The message I get with disk utility is: Unable to attach "Macintosh HD.dmg" (No mountable file systems)
So I click okay, and verify the disk, and I get ALOT of incorrect block counts (should be 1001 instead of 1020220) for example..
After checking multi-linked files and such, disk utility tells me to "repair disk" But I cannot mount the image, therefore I cannot repair it. I tried to repaid the DMG itself, but nothing happens.
Any info would be awesome.

converted corrupt DMG to CDR with disk utility. Some data loss occurred, but I got the majority of my files back.

Boot Camp Assist can't partition hard drive

Boot Camp won't partition my 500GB internal HD. I get the message:
"The startup disk cannot be partitioned or restored to a single partition. Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again." I had recently used SuperDuper to replace my original single partition internal HD with the new 500GB HD with three partitions. I had not setup Boot Camp on the original HD. After getting the Boot Camp Assist error message on the new HD I used SuperDuper to clone back from my original HD (which was now external) with a single Mac OS Extended (Journaled) volume. I then ran Boot Camp Assist again and got the same message. I ran Disk Utility Verify Disk Permissions and got some errors which I then successfully repaired. I still get the same Boot Camp partition error. Any suggestions?

When you partition your drive you are given the option to format it for OS 9, if you choose this option your drive will be formatted to be incompatible with Boot Camp. This incompatiblity will remain when you put it back to a single partition unless you go to options and select the top radio button (format for Intel Mac) to create a GUID Partition Table (at least that's what I did and it fixed the problem).

How to install boot camp on a pre-partitioned HD ?

Hi,
I have just done a clean install of my mac. Before installation i used disk utility to create a few partitions, one of them made available for Boot Camp.
Now when i start the Boot Camp Assistant it tells me:
"The startup disk can not be partitioned or restored to a single partition.
The startup disk must be formatted as a single mac os extended (journaled) volume or already partitioned by Boot Camp Assistant for installing windows"
What the h.... do i really have to start over AGAIN?!
I need 3 mac partitions and 1 windows, if i re-install, then use boot camp assistant to create a windows partition i'll be left with just 2 partitions.....
Any help is very welcome at this point.

You don't need to run Boot Camp Assistant since you've already partitioned the drive. Just boot to your Windows disc and follow the installer set up. All Boot Camp Assistant does is partition the drive for you.
However, I'm pretty certain with that many partitions, depending on the order in which you've placed them, you will run into some errors trying to install Windows on the Windows partition you've created. I believe the Windows installer doesn't like to install on anything higher than partition 4. If your Windows partition is #3, and your Mac OS partition is #2, you may still encounter an error, but this has a far easier workaround than having the Windows partition be higher than partition #4.
Let me know how you've set it up.

Boot Camp 5 Windows 8 partition

So I haven't dual-booted in a while, I used to run Windows 7 Ultimate. Boot Camp worked fine. I recently have been trying to install Windows 8 Pro and Boot Camp just will not partition my drive. It keeps saying "An error occurred while partitioning the disk". I've tried it both with a bootable 8GB USB plugged in and an install DVD. I'm giving Windows 45GB and that leaves OS X with 101GB. What am I doing wrong? It's a MacBook Pro 13 inch, Early 2011, 500GB HDD, 8GB RAM, etc. etc.

Boot Camp Assistant creates non bootable Windows drive

Hello all
I've been trying, for the last 8 hours to install Windows via Boot Camp without any success
Some information:
MacBook Pro (13-inch, Early 2011)
OS X Yosemite
Windows source file: en_windows_7_professional_x64_dvd_X15-65805.iso
1. The first problem I had was that Boot Camp wouldn't enable the "Create a Windows 7 or later version install disk"
     1.a) I tried burning a DVD without success
     2.b) I finished by changing Boot Camp Content Folder as instructed here.
2. Once, with the USB installed I partitioned my HD via Boot Camp but, after restarting the computer, I would receive a message asking me to insert a valid bootable drive.
     2.a) I searched some more and found out that only GUID partition type USBs will boot.
     2.b) I checked the USB Partition Map Scheme and it says: Master Boot Record
     2.c) I changed the partition type back to GUID but, of course, when Boot Camp reinstalls Windows it goes back to MBR...
3. Why in the earth would Boot Camp create a non bootable bootable drive???
4. What am I doing wrong?
Thanks a lot!

On Macs with built-in Optical drives as indicated for your Mac (MacBook Pro (13-inch, Early 2011) - Technical Specifications) you need to use a DVD.
There are only a couple of 2012 models which support either USB or OD.
Creating a USB with ISO can be done either using a tool like Rufus or http://technet.microsoft.com/en-us/library/jj200124.aspx . BCA will use the Mac's model identifier to set booting. There is no work around for BCA. You can try these two see if you can make any progress.

Boot Camp Error "You cannot partition an external disk drive"

Hi all - I am trying to install Windows XP Pro via Boot Camp for the first time. I have all four bays of my MacPro (circa 2007) filled with hard drives. I boot off the first bay, and have a cal digit raid card that controls the other three hard drives into a RAID5 array. I believe that the raid card may be the culprit.
I am trying to install boot camp/WinXP on the first drive. I get the error in the title above when I try to run Boot Camp. I have ejected the RAID5, and I have rebooted to no avail.
I cannot wipe my first drive/boot drive clean. I just wish to partition it via BC so I can switch between XP and Mac OSX. Any guidance is appreciated.
Thanks.
Tri

Try removing the other drives is almost always essential with a Mac Pro to get Windows to work. Even Windows 7 doesn't understand seeing Apple GPT/EFI during install - they can be reinstalled later.
Or it could be that any hardware RAID controller also has to be removed. Like Apple's Pro RAID or ATTO FC.
Even w/o the CalDigit and just Apple GPT you would have gotten an error message.
BCA is still after all these years unable to understand and work with a Mac Pro properly. A one-trick/ one-drive only utility that is stumped when it runs into a dual drive setup. Which way why I gave up on using Mac Pro for dual-boot and built some PCs just for Windows 7. I install Windows on PC, then transfer the drive to Mac Pro and it works just fine!

Boot Camp Assistant: Can't Partition Drive

I've been trying to partition my hard drive using the Boot Camp Assistant so I can install Windows XP. However, whenever I try to partition the drive, I get an error message saying that my hard drive needs to be a single Mac OS Extended (Journaled) volume. I opened up Disk Utility to see what was wrong, and it said that my only hard drive, Macintosh HD, was formatted as a Mac OS Extended (Journaled) volume. I tried bumping the partition size down from 15 gigs to 12 gigs; the progress bar was a little under 25% full when I got the error message again. I'm planning on arranging to get support at an Apple Store, but I wanted to see if anybody on here knew what to do first. Any ideas?

okay so i did what you said and i selected restart under superduper clone so i could test to make sure the clone worked...but now i can't get it to restart under my Macintosh HD. the clone works fine but it is on my external hard drive. i need y internal hard drive to be my start up disk so i can use boot camp assistant. i went to system preferences->startup disk but it only shows my clone on my external hard drive. any suggestions?
When you tested the clone, did you change the default boot to the clone? You should have simply booted by holding down the Option key.
I don't know what happened to your HD or original OS, but if you reboot and hold down the option key, your original OS should show up in the selection menu.
If not, boot into the Leopard DVD (press "C" key during boot) and after the language screen, in the menu, top left under Utilities select disk utility and run it, repairing HD and permissions. Then see if you can reboot into the original OS. You may have to hold down Option key again until you boot it and change the default back to the original OS.

Boot Camp Assistant crashes when partitioning drive (exception: EXC_BAD_ACCESS)

I run Mountain Lion, a fresh install, brand new Macbook Pro. HD: Samsung 840 Pro 512 GB SSD.
When trying to go through Boot Camp Assistant / Setup it works fine until it wants to repartition my drive. It then quits unexpectedly and returns these errors:
Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x000000000000003c
Everything else on this new machine works like a charm. I checked permissions, verified the disk - no issues whatsoever.
Can anyone help me out with this?

I had the same problem, so I decided the system had too much going on. I stopped Time Machine and unmounted the disc, then I closed every other running program except Boot Camp, disconnected all unnecessary devices, selected the partition size and then didn't touch a thing, just went and made a cup of coffee. When I came back it had started and eventually partitioned fine.

Boot Camp Assistant won't partition drive

I have a new Mac Pro with a clean install of 10.5. No previous Boot Camp installation, nor has Parallels been installed. I have two 500gb drives and two 250gb drives installed. I want to partition one of the 250gb drives to install Boot Camp and XP. I've tried to use the Boot Camp Assistant but it won't partition the drive. It seems to start the process, but never gets off the progress bar and eventually I have to Force Quit and reboot. The drive I'm trying to partition is freshly erased with Apple's Disc Utility (formatted with Mac OS Extended (Journaled)).
Am I doing anything wrong? I successfully installed Boot Camp on my MacBook Pro using Boot Camp Assistant, but nothing I've tried with my Mac pro seems to work.

Check that it has GUID partition table.
Disk Utility Partitions -> Options
Click on drive (not partition) in First Aid and look at the bottom of the screen.
50/50 partitions?
You could just use Disk Utility, make one FAT, then format it again if needed in XP. That lets you use the first partition outer tracks).
If you choose MRB, BCA will only use the entire drive. I wanted half NTFS and half FAT so I did it on my own.

Boot Camp / Windows 8.1 64-bit / Driver compatibility issues

Hi everyone,
I have been struggling to install Windows 8.1 Pro 64-bit version through Boot Camp on my MacBook Air 13 inch mid-2012 for a few days and I have finally decided to give up and write this thread to see if anyone has encountered the same problems as I have and if they've found a solution.
What I've tried so far:
1. First attempt
     a. Download the ISO from Microsoft (We are a Microsoft Partner and have access to internal use licences of Windows 8.1).
     b. Use the Boot Camp utility to create a bootable USB drive, download the latest Boot Camp drivers and partition my SSD drive.
          Issue: Upon rebooting, I got the "No bootable device found" error message. I still tried to boot on the USB drive, which I was able to, but           when installing Windows, I was unable to format the partition created by the Boot Camp utility as it contained a "MBR partition table"           instead of a GPT.
2. Second attempt
     a. I searched the Internet about the error message about the MBR partition table.
     b. The solution I found was to format the partition created by the Boot Camp utility as "Free space".
     c. I was then able to start Windows installation by formatting the partition I wanted to allot it to through the Windows installation process.
          Issue: The installation went smoothly until my computer rebooted the first time and the "Peripherals preparation" step (sorry about the           approximate translation, I'm used to the French version of it) got stuck at 10% and was brutally followed by a black screen. Forcing the           computer to restart would show the Windows logo and go straight back to the black screen situation...
3. Third attempt
     a. I decided to create a bootable Windows installation USB drive using UNetBootin utility and creating a "Free space" partition through Disk      Utility on which to install Windows.
     b. I then booted on the USB Drive and was able to install Windows properly.
     c. I donwloaded the set of Boot Camp drivers through Apple's wesbsite corresponding to my MacBook Air model.
          Issue: Somehow, the graphics driver installed by Boot Camp made my system crash as I got a black screen when it tried to install. Even           without doing anything and having Windows try to install the right driver by itself, I got a black screen and an unusable installation of           Windows 8.1.
What am I missing here? Why isn't the Boot Camp utility working when it should be so easy? Is there a compatibility issue of my graphics driver (Intel HD Graphics 4000) with Windows running under Boot Camp?
Thanks in advance for your help. I'm in desperate need of a solution as I don't want to go back to using virtualisation softwares such as Parallels Desktop, VMWare, etc. though they work just fine...
Best regards,
Alex

1. Your MBA does not support EFI/Free Space method.
2. You need to ensure that your USB is a USB2 device.
3. The MBR should be checked, because there are known cases where BCA fails to create the MBR.

Windows 8-Parallels 8-boot camp-disk cannot be Partitioned

Ok, I wanted to try out Windows 8 on my Mac, so I got the Parallels 8 bundle pack...but after looking into it...I was led to believe that initially using boot camp and then migrating that to Parallels is a better route. So first question is...Is that true? Should I really start with Boot Camp?. Secondly...(which is what led me to ask if I should really do it this way) I tried to run Boot Camp Assistant and I got "The disk cannot be Partitioned because some files cannot be moved...Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again." Backup, Format, and Restore scares the crap out of me...I'm terrified that I'll lose everything. I have a TB external HDD to which some is partitioned for Time Machine and the rest partitioned as personal storage...personal storage is where I have my iTunes library and iPhoto library stored and a bunch of other stuff. Now some of what I've read is to get a new external HDD, zero it, back up and restore...my question is do I really need to do that with my current set-up? If I already have the external HDD with my time machine back ups on it? I've also read that this may not be necessary...and that it may be possible to restart in recovery mode and "Repair". I apologize for the long winded question...I just want to make sure I give enough info and that someone can help. Any assistance would be greatly appreciated.

You do not need to use Boot Camp nor install Windows on a Boot Camp partition in order to use Parallels. I think you may have misunderstood. If you already have Windows installed in Boot Camp, then Parallels is able to use that installation for it virtual machine.
On its own Parallels creates its own disc image on which it installs Windows. That disc image functions as a normal Windows hard drive. You can create any number of virtual machines where each one has its own separate disc image.
"The disk cannot be Partitioned because some files cannot be moved...Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
The above error occurs because you have asked for an amount of space for the Windows partition which cannot be accommodated because Boot Camp Assistant was unable to find sufficient contiguous space to satisfy the request without having to move some files. However, those files could not be moved. The solutions are: 1. reduce the size demanded until Boot Camp is able to accept it; 2. re-partition the drive back to a single volume, reinstall OS X, create the desired Boot Camp partition, then restore all your files.

Low disk space (Boot Camp) - can I repartition my hard drive?

Hi there -
I am a MacBook user through and through. However, I partitioned my hard drive 3 years ago using Boot Camp to do some light Windows-only work. I only partitioned 8 GB to Windows, which wasn't a problem til now. I'm now trying to use some Windows-only software again, but am faced with a "low disk space" message. I cleaned up as much as I could with 8 GB, but it's still not enough. Can I re-partition the hard drive to more like 20 GB without losing any of the data and/or installed software (I don't have access to the install disks...)? I tried to install WinClone but I have OSX 10.5.8, and it said it only runs on 10.6 or 10.7. Can anyone offer advice on an option to re-partition with Boot Camp, without losing the installed software and files/data?
I have a MacBook running OS 10.5.8 with 2.16 GHz Intel Core 2 Duo and 2 GB 667 MHz DDR2 SDRAM (I know, it's old!!!)
Thanks

How do you Install Win XP using Boot Camp without use of an optical drive?

So I'm about at my wits end. I'm try to get Windows XP on my OS 10.5.5 MacBook Pro. I've run into what seems to be a bit of a dead in. Unfortunately my optical drive has gone stupid on me and won't allow me to get through the entire set-up. The Mac has know trouble seeing the Installation Disc. After my partition has been created and I click start Windows Installer, the computer reboots in a normal fashion up to when you get the apple with spinning progress wheel. At this point the screen goes black and I get a "-" blinking in the top right corner of the screen. I figure it's just trying to boot from Win Install disk but it just kinda sits there. So here's my question. Is there some way to boot this Windows Installation from anything else but the CD? I luckily have an image of the WinXP CD in about 5 formats. I'm going absolutely crazy because I had just Installed WinXP not more than an hour before I ran into this initial problem but wanted to change the WinXP partition to FAT 32 as opposed to the NTSC format I accidently used. I would really appriciate any help in my dark hour.

Kirkdan:
I really would like to help you and get your issue resolved in your dark hour as you said. I am afraid that I do not have good news for you. This is because the limitation put on by this entire process of installing Windows via boot camp.
The answer to you question to install windows from any other medium other than your built-in optical drive is a NO. This won't work since once Windows begins to install then it will not have all the drivers installed to recognize the external CD drive (USB/Firewire) and installation will halt.

"No Bootable Device" after failed Boot Camp installation (Windows 8 - 1TB Fusion Drive)

On my new iMac /w a 1TB Fusion Drive, I tried to install Windows 8 (still technically unsupported) using the following method:
http://arstechnica.com/information-technology/2012/11/no-support-no-problem-inst alling-windows-8-on-a-mac-with-boot-camp/
Everything was proceeding just fine; I had Boot Camp copy all of the Windows 8 files (a legitimate, store-bought copy) to a bootable USB drive - a feature only available on new Macs running Boot Camp Assistant that don't come with an internal optical drive - and create a 102 Gb partition on the Fusion Drive. It then rebooted and was proceeding through the Windows 8 setup wizard as should be expected, but it couldn't modify any of the partitions on the Fusion Drive and wouldn't proceed. I accepted defeat and decided I would just wait until Windows 8 is officially supported before trying again.
Now, every time I turn the computer on, I get an error message saying "No Bootable Device...", unless I hold down the Option key and manually select "Macintosh HD" (the only boot device listed). I already removed the primary Windows 8 partition, but it hasn't fixed the issue.
I'm thinking that it's one of the 'hidden' partitions causing it to behave like this, or something wrong with the EFI bootloader, but I don't know how to proceed. Any thoughts on this?

I actually did try this (forgot to mention it), and it didn't fix the problem.
However, I just resolved it on my own, doing what I probably should have tried before anything else: running "Repair Disk" in Disk Utility updated all of the boot preferences as it should have.
