Bootcamp 5 + 3TB HD: The startup disk must be formatted as a single Mac OS Extended (Journaled) volume

Hi all,
I installed a brand new 3TB Seagate Barracuda HD in my iMac late 2009 after read that apple provides a patch to use 3TB discs with bootcamp with 10.8.3.
I tried to install windows in my 3TB disc 4 o 5 times, reinstalling from scratch, formatting the disc from terminal, etc... I tried everything and I keep getting the same message: The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.
The disc has a single 3TB Mac OS Extended (Journaled) partition, but bootcamp keep saying that is not... and doesn't allows me to install windows. I read a lot of discussions here and other communities but as I said, none solution worked for me.
Any of you could manage to fix this issue?? Is Apple aware of that problem?
Any idea will be welcome!
Ivan

Hi,
Anybody in the forum have managed to use bootcamp with a 3Tb disc?? or get any answer from Apple...
Regards,
Ivan

That's essentially what Solving Boot Camp partition creation problems says. What is your question?

Boot Camp error: The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Jounraled) volume or already partitioned by Boot Camp Assistant for installing Windows.

Hi!
I am getting the error:
"The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Jounraled) volume or already partitioned by Boot Camp Assistant for installing Windows."
I read up some on google, but all of them says that they have crated a partition and that is the problem, I only have the standard "Macintosh HD".
I tried to create a partition manually in disk utility but then the error message: "Partition failed with error message: Could not unmount disk."
Can anyone help me? It's driving me crazy.
Thanks.

This message, and threads like yours got asked daily for over two years, now it is only a couple times a week!!
Is it so hard to follow through? you were to have backup already, clones are best, then erase/format and restore.
Then partition.
Some have been able to use Disk Utility booted from OS X DVD or another drive, and repair the drive.
You have to use Boot Camp Assistant (99.9% anyway) to create and achieve a proper Windows Master Boot Record partition.

I need help with boot camp. "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."

This message appears every time I try to partition my disk:
"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 verified my Macintosh HD disk on Disk utility and then tried to repair it, but I am unable to click the repair button.
It says it's not available because the startup disk is selected.
I don't know what to do or how to go about both these problems.
Please, any suggestions?

Odd problem with partitioning the disk-- it says it needs to be a single Mac OS Extended (Journaled) volume, but it already is? (Screenshots in post)

I have a 1 TB Macbook Pro running Mavericks.
My disk is a single-volume...
Here is the information on my disk:
And I'm trying to use boot camp assist to partition my disk, like this:
But when I do, I get this error message:
"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."
It already is a single Mac OS Extended journaled volume. Right? Here is an image from Disk Utility:
Any ideas?

Hey there!
It sounds like you are unable to install BootCamp due to an error that your some files cannot be moved, and to format your disk as a single volume, but you have confirmed that it already is. I would verify and repair your disk permissions with the following article next, if you have already restarted your computer and tried again:
Disk Utility 12.x: Repair disk permissions
http://support.apple.com/kb/ph5821
Choose Apple menu > Software Update to make sure you have the latest version of Mac OS X.Software updates sometimes change a file’s permissions to improve security, so updating your software can solve some permissions problems.
Open Disk Utility, in the Utilities folder in Launchpad.
Select the disk you want to check.You can verify or repair permissions only on a disk with Mac OS X v10.7 Lion installed.
Click First Aid.
Do one of the following:
Click Verify Disk Permissions to test permissions.
Click Repair Disk Permissions to test and repair permissions.
Disk Utility repairs the permissions for files installed by the Mac OS X Installer, Software Update, or an Apple software installer. It doesn’t repair permissions for your documents, your home folder, or third-party applications.
If that does not resolve the issue, I would next verify and repair the disk with this:
Disk Utility 12.x: Repair a disk
http://support.apple.com/kb/PH5836
Thank you for using Apple Support Communities.
Take care,

Installing bootcamp, pauses and reads "Back up the disk and format it to a single Mac OS extended journaled"

I just ran disk utility as promted and checked, the main disk is already formatted to a single Mac OS extended (journaled).
It previously had parallels partitioning, it is still installed and I can't uninstall it, could this be the problem?

No, Parallels does not create a partition, it's just another program.

I had formatted external HDD as Mac OS Extended(journaled) earlier, but now i want to format the same as ExFAT so that i can copy files between PC and MAC. But it is giving 'Can't unmount' error while i try to run Erase

Use the PC to reformat the drive.

Boot Camp - Startup disk must be formatted as single partition

Hello,
I have recently came across an issue. After reinstalling OS X, I wanted to install Windows 7. I went to the assistant, and it stated that it needed
to be formatted as one partiton. The thing is i have formatted only last night while installing os X, with the partition "Macintosh HD", as a Mac Journaled partiton. Now, when i see in disk utility, i see another partition, "Recovery HD". As a Mac owner for several years, the Recovery Partition never appears on Disk Utitliy, and now it thinks its a second partition! I have not touched the partitions since reinstalling only a couple of hours ago. Any help would be much appreaciated.

Thanks, i just deleted the recovery partition because mac has the internet recovery feature!

Bootcamp Yosemite 10.10.1 "The startup disk cannot be partitioned or restored to a single partition."

I'm trying to install Windows on my Mac via Bootcamp. I start up Boot Camp Assistant, the introduction pops up, I press continue and then I get this error message.
"The startup disk cannot 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."
So I head over to Disk Utility, the only partitions I have are Macintosh HD and EFI. I thought there might be some hidden partition, so I went into debug mode in Disk Util and there's nothing (Also used terminal, I'll put results below*). So that brings me to my current problem; it's already "formatted as a single Mac OS Extended (Journaled) volume" and I can't make it "partitioned by Boot Camp Assistant for installing Windows." because this error message prevents me from doing that. Maybe there's an easy fix, but the information provided is so unhelpful/circular it makes me want to laugh and punch something at the same time. I saw that someone fixed this problem by merging their partitions, but as I already have the minimum number of partitions so that wouldn't fix anything (unless EFI is unnecessary, which I'm fairly sure it isn't).

Thanks for your help in advance ;3, I hope this is an easy fix

I had a similar issue after doing a fresh install of Yosemite. Bootcamp assistant seems to want a Core Storage scenario before it will continue.
To convert your drive use the following command in Terminal:
diskutil cs convert disk0s2
Bootcamp will then let you proceed as normal. Be warned though!
After the windows install completes you may end up with something like my situation:

How to fix this error? The startup disk cannot be partitioned or restored to a single partition.

Hey guys,
I am trying to install windows 7 ultimate 64 bit via bootcamp assistant. I open bootcamp assistant from utilities and i get the second window and try to click continue and i get a pop up, saying "The startup disk must be formatted as a single Mac OS Extneded (journaled) volume or already partitioned by Boot Camp Assistant for installing Windows." I looked around on the internet, i found that my internal HD must be set to OS Extended (Journaled). I went into disk utility and i clicked partition tab and the option was set to OS extended (journaled). Any ideas on how to overcome this error so i can install windows 7?

Error is:
1: common
2: misleading and poorly worded
3: space must be:
A: contiguous, that means unfragmented and in ONE section, not multiple
B: files cannot be loced, anchored or in such a manner as to prevent or block partition operation
C: to move, unlock and shuffle files requires booting from another drive or device
Shrink the HFS+ volume by as much or more than you need to set aside to use
If that does not,
Try iDefrag from another hard drive or by burning and using its own CD that is just for consolidating free space
Clone your system (should have backups already, clone is just bootable)
Erase and restore from clone - SuperDuper does consolidate files and free space and result in unfragmented (99% success rate)
None of which has to do iwth what that error message says. This error has been almost a daily threat topic - has gotten less but has not "gone away."

Why i can't find the external HDD plugged to airport extreme. i already format it with mac OS extended (journaled)

Why i can't find the external HDD plugged to airport extreme. i already format it with mac OS extended (journaled).
Does only certain branch of HDD can be connected to aireport extreme?
I collect some information and i knew i have to partiion the HDD into Mac OS extended (journaled),
and i did so. Still the usb HDD cannot be found.
The other question is, can i partition the HDD into two sections, one of it is Mac OS extended(journaled) while the other is Fat32?
I want to share Fat32 section with another PC with windows system.
Thanks a lot if you have any suggestions.

I had tried to set up the connection via usinb a powered usb hub as the bridge between external HDD and the airport extreme. i still cannot found the HDD in the "airport utilities".
This is my setting.
1. Set airport extreme as "sharing-single-ip" mode. The wireless network functions correctly.
2. Connect external HDD to MBA. Partition it into single-partition with Mac OS extended (journaled).
3. The HDD can be found if i plugged it directly to my MBA.
4. Connect a powered usb hub to airport extreme.
5. Connect external HDD to the powered usb hub.
6. Open airport utilities.
a. Select "airport extreme" in the sidebar.
b. Change the "Disks" sheet.
7. Cannot find an external Disk
Is there any problem here?
Please help me. Thanks a lot!!

I'm getting this error with bootcamp "The startup disk does not have enough space to be partitioned"

Here's the story...
I had a dual boot configuration on my mac with Mac OS X Lion and Windows XP (made with bootcamp).
I decided to reinstall windows.
I deleted the windows partition using BootCamp.
Tried to recreate the Windows partition with Boot Camp and got: "The startup disk does not have enough space to be partitioned You must have at least 10 GB of free space available"
After reading several posts on this forum I decided to defrag the hard drive and try again.
The defrag did not work and I'm still getting the error, I have 22 gb of free space on my drive.
Any suggestions?
Also, I tried repair disk and repair permissions
Hmm, my external harddrive says on the box "OS X 10.5.8 or higher (32-bit kernel only)" Could the 32-bit requirement be an issue? Is lion 64-bit?

Boot Camp must be able to allocate a contiguous block of space on the drive. If it cannot find 10 GBs of contiguous space, then you cannot create the Windows partition.
You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive.
Get an empty external hard drive and clone your internal drive to the external one.
Boot from the external hard drive.
Erase the internal hard drive.
Restore the external clone to the internal hard drive.
Clone the internal drive to the external drive
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive and click on the downward pointing arrow button.
After startup do the following:
Erase internal hard drive
Open Disk Utility in your Utilities folder.
After DU loads select your internal hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed. Do not quit Disk Utility.
Restore the clone to the internal hard drive
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the internal hard drive. Source means the external startup drive.
Note that the Source and Destination drives are swapped for this last procedure.

Hello, Trying to run Bootcamp on my 15" Macbook Pro (Maverick).60 gig available on my computer's hard drive and 250 gig on a separate hard drive that I have attached which is single partitioned. Keeps saying "The startup disk does not have enough space"

Hello,
I'm trying to run Bootcamp on my 15" Macbook Pro (Maverick). I have 60 gig available on my computer's hard drive and have 250 gig on a separate hard drive that I have attached, which is single partitioned (MS-DOS FAT). It keeps saying "The startup disk does not have enough space, you must have 28 gig of free space available" Does anyone know what I'm doing wrong? Any help would be much appreciated.

Thanks for the advice Bob The Fisherman. I'm just reading what turbostar has kindly written and it appears that perhaps, if I take advice from you both, I need to free more space up on the computer's hard drive?
With the external hard drive; would it be advisable to defragment? Know of any defrag freeware for Mac OSX?
Many thanks to you both.

Bootcamp error, 'the startup disk cannot be partitioned or restored to a single partition.'

I am trying to set up bootcamp for gaming purposes.
I attempted this several months ago and was able to proceed to the point of accessing the Windows disk utility but noticed that I was running out of memory on the partition. I believe I deleted the partition through mac OS, thinking I would simply re-run Bootcamp. Honestly, I have forgotten the details but now am unable to get past an error message on Bootcamp saying, "The startup disk cannot be partitioned or restored to a single partition."
Also, when I look at my disk utility settings I see I have two Macintosh HD with exactly the same numbers, i.e. 1.94 TB free of 2.09 TB.
Any assistance with this would be appreciated.
Thank you.

Hello,
I've been stuck for some hours now trying different things to install Windows 7 on my Macbook Air, and I think now is the time to call for some custom help.
I'm using OS X 10.9.5 Mavericks.
So some months ago I just wanted to run Linux on my laptop so I installed rEFInd, shrunk the Macintosh HD partition by 25GB and booted on a linux live USB flash I burned using dd.
Then I used gparted to create my linux partitions.
It worked just fine, even though disk utility from OS X seemed quite unhappy about this (it seemed to have incorrect informations about the filesystem on these partitions, seeing them as journaled Mac OS while they were clearly not). At this point already, the Recovery HD from mac showed up in disk utility, which I found weird but didn't bother me.
But recently I needed windows on my Mac. So after a few tries for the triple boot, I managed to create a bootable USB stick with boot camp, which already showed me the message "The startup disk cannot be partitioned or restored to a single partition" and hence refused to partition/install himself.
So I thought "OK, that's no big issue, I can just partition with disk utility and then boot on the USB stick and everything will work fine". But when EFI booting on the USB flash drive I got stuck at the beginning of Windows installer with no keyboard or mouse support.
After some hours spent googling, I was unable to find a working fix for that, and as there was no support for my case (where I used bootcamp to create the bootable flash but NOT to partition/reboot) I decided to give bootcamp a try.
So I erased my linux partitions, and cleaned up everything I could on the HD with disk utility. That means I now have two partitions showing in disk utility : Macintosh HD and Recovery HD.
When using disk utility from terminal, the list is :
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            80.0 GB    disk0s2
   3:                  Apple_HFS Recovery HD             650.1 MB   disk0s3
But boot camp still isn't happy, and the message "The startup disk cannot be partitioned or restored to a single partition" keeps popping after the intro and I can't partition/boot from bootcamp.
So, as I don't understand what is wrong here anymore, any help would be greatly appreciated!
I will be watching the thread a lot because I really would like this resolved (or windows installed one way or another) this weekend; so any questions on my past manipulations or config just ask!
Thank you.

keyboard issues are also something of a common issue.
I wish the best threads were voted to the top of forums, something! Me, I literally burned out here, but after installing 10 Preview, wanted to "see what was going on" after hiatus of a couple years and see if anything had changed (no, not really!)
Also, these new Communities are not putting "more like this" and failing to help too.
I think rewriting Boot Camp Assistant's built in help and pdf would help a lot, and needs to be clearer and go into details. And Yosemite was not it seems tested against Boot Camp, and drivers for new Macs + new OS also lag behind. Again, common and no sign of improvement or change.
One of the tricks to the "can't partition" is rather simple - of course backup is step #1 and is spelled out - SHRINK the main HFS+ partition! then stretch it back to full length. Sometimes a reboot is needed, and sometimes even do a Safe Boot - not sure what but Recovry Mode might be a good option too. That does seem to consolidate free space, move files that are locked and cannot be moved otherwise, and allow BCA to partition, jusst be sure to have enough space left and large enough for a proper Windows install (and fudge factor).
