Boot Camp can't create a Windows partition

Hello,
I'm trying to create a new partition to install Windows 7 on, but I am unable to do so.
At first I tried to do this with Boot Camp Assistant, but it didn't work.
Then I tried to create a FAT partition with Disk Utility, which didn't work either.
So I verified and repaired the disk, tried to create the partition again, yet it still didn't work.
I verified and repaired the disk and tried to create the partition while running the OS, in Safe Mode and from the Mac OSX Install DVD.
Neither of them worked.
I noticed while running the OS, the info of the HD said the capacity is 749.81 GB, while checking that from the Mac OSX Install DVD it only says about 700 GB (I mentioned 698.6 GB).
Strange..
It might also be important to mention that I recently (2 days ago) I installed a new HD: Western Digital Scorpio Black 750 GB, and today I swapped my 2x 2GB RAM for 2x 4GB RAM (Samsung).
On my previous HD, the Fujitsu 250GB, this proces was no problem at all. I installed W7 on that drive just a week ago.
I made a clone of the Fujitsu HD and "back-upped" it to my new WD HD. The W7 partition on the Fujitsu HD was 50GB, which is the difference in capacity mentioned above. I'm not sure if there's a link here..
I've got a MacBook Pro from mid 2009.
I'm not sure what to do next... I'm stuck!
Any help is greatly appreciated!

Did you do an upgrade to Leopard? If so, some files may be scattered over your HD, making it impossible for BC to find a single contiguous area on the drive.
Also, be sure you did not have eDisk installed - that's the thing from the TechTools disk that comes with AppleCare.
This is not an uncommon problem. It's not just you.
If you have a complete backup of Leopard, you can use the DU to make a single partition. You may be lucky and not lose any data, but backup anwyay.
In DU, repair the disk, if necessary and verify/repair permissions.
Once you have done this try again.
If BC still fails, you will need to erase the HD and then copy everything back from the backup.
I always suggest a bootable clone for the backup and be sure to test it first to see it works.

Can't create a windows partition

I'm trying to create a windows partition through bootcamp but it refuses to do so because I'm guessing that it's scanning permission that need to be repaired. The message states that I need to run disk utility.
The problem though is, I can't do anything about the permissions cause of a known "bug" (??) on leopard.
It states 3-4 permission need repairing but they can't be repaired. Others have that issue but they probably had windows installed before this happening.
here is an image of disk utility.

Alright I solved the problem. It was a repair disk and a repair permissions check.
Everything is fine now

Can't create a windows partition with bootcamp

Hi
i have a MacBook Air. Standard, no changes from my side.
I have the newest Lion update and BootCamp in Version 4.
So, now i want to install Windows 7 64 Bit.
I start BootCamp Assistant.
The first point, is grey. i can't activate it. This point is to create a Windows 7 Install Disk
Second Point is to download the drivers and so on. This is working. I have the stuff on a usb stick.
Third Point is to create/install Windows 7. So, i have the posibility to decide how big i want my windows partition. 20-32 GB.
when i click on create button. There comes a pop up "Installtions CD is not found"
I have a bootable Windows 7 USB Stick (8 GB - Fat32). The Stick works. When i boot with refit from the stick, the Windows 7 installation starts. But without a partition ... not so good :-)
So, what can i do now? BootCamp don`t want the Windows USB Stick.
I need help :-)
Thanks

You will need a windows install DVD, and 50 to 60G partition.

I get an error message saying, "An error occurred while restoring the disk to a single partition." when I try to use Boot Camp Assistant to remove my Windows partition. Help?!

I'm trying to remove my Windows partition and delete Boot Camp altogether off my laptop. When I try to remove the partition, I get an error saying "An error occurred while restoring the disk to a single partition."
Can someone please help?

Boot from another hard drive or DVD and repair with Disk Utility.

Boot camp not showing ''Create a Windows 7 install disk''

So i am trying install windows 7 64 bit version on my 2008 macbook pro and i dont know if this is the problem or not, it doesnt show ''Create a Windows 7 install disk''.
The other thing that i have not made clear is, when doing a windows 7 cd, do i need to burn ISO file on DVD or should i open it and burn all the files inside the iso image, to the disk?
Is there any specific ways or versions of Windows 7 for bootcamp or i can dowload any tipe of windows 7, put it on cd and use it as a bootable CD?
P.S.: I already had windows 7 ultimate 64 bit installed on the macbook. I installed it from my friends copy of Windows 7 Ultimate and i cant find that CD anymore, so when i tried to do a new copy of windows on CD and do the bootcamp it didnt recognize it, like there was no installation disk. That means i should make a bootable CD with windows 7 files on it or what?
Thanks for help.

Failed boot camp install - how to remove windows partition?

Hi There,
After a failed boot camp install, boot camp no longer sees (or can remove) a windows partition - Disk Utility can't seem to remove it and if I use:
$ diskutil list
It shows up as partition 5 "Microsoft Reserved"
I also have a portion of free space that I can't seem to incorporate back into the main OSX partition - how do I remove the windows partition and make the drive a single OSX drive again?
Any help would be much appreciated
Cheers
Ben
- New Mac Pro
- Installing onto internal 1 TB SSD
- 10.9.3
- Windows 8.1

Just incase others have this issue, this wasn't caused by using Disk Utility (Disk Utility couldn't remove the partition anyway) it was caused by repeatedly trying to format the Boot Camp partition using the Windows installer when Windows refused to install.
The solution is an Apple tech note (I can no longer find it sorry) that sates that no other hard drives besides the internal HD and the Windows USB flash drive can be connected while installing windows.
Cheers

I get an error message saying, "An error occurred while restoring the disk to a single partition." when I try to use Boot Camp Assistant to remove my Windows partition.

i don't know how to do

There is a forum for Boot Camp. This is not the forum for the notebook users.
You should always always have backup that you can use to restore your system incase of a problem.
Try booting into Lion Recoverey or from your OS X DVD and choose Disk Utility from Utility menu and repair the disk; try to remove with DU instead of BCA.

HT5446 If I buy a mac mini with a fusion drive and add windows using boot camp, can I make the SSD function be dedicated to the windows partition?

If I buy a mac mini with a fusion drive and add windows using boot camp, can I make the SSD function be dedicated to the windows partition?

Additional information from Linc's post. Basically, only one additional partition can be added to a Fusion Drive and it resides on the HDD.
Do computers that come with a Fusion Drive support Boot Camp?
Yes. Use the Boot Camp Assistant to create a Windows partition and install Boot Camp. The Windows partition will exist on the hard disk drive, not the Flash drive, and is not part of Fusion Drive Logical Volume Group. 3TB Fusion Drive configurations need to update to OS X Mountain Lion v10.8.3 or later to install Windows 8. See iMac (27-inch, Late 2012): Boot Camp alert with 3T hard drive for more information.

How do you create a windows partition?

I have a conference call with a microsoft program. I was told that I need to create a windows partition. How do I do this??
Thank you!

Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak2, Vista, or Windows 7. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.
Open Boot Camp Assistant in the Utilities folder. In the opening window click on the Print documentation button. Read documentation carefully then proceed to use Boot Camp Assistant to create your Windows partition if that's what you choose to do.

Boot Camp one more partation in windows 7 Professional 64 bit

I installed Marwicks and through Boot Camp Windows 7 Professional 64 bit and After installing windows 7 professional 64 bit I want to create another partation in windows but when i am creating another partation through windows disk management I am able to create another partation but after creating another partation it changes all disks to dynamic disks.
When I am coverting back disks from dynamic to basic disk through third party software it changes disks back to basic from dynamic disk except new partation.
And it leaves new partation as a unallocated space.
Can someone help me how to create one more Partation in windows 7 Professional 64 bit.
Many Thanks in Advance

Once you install Windows on a Mac you can NOT FOOL with any of the partitions in Windows or in OS X.
Hopefully OS X still boots. At startup hold down the Option/Alt key to get the Mac Boot manager/selection screen. Select yopur Mac OS X drive and boot to it. Run Boot Camp assistant and Remove the Windows partition/s if you can.
If not use Time Machine to backup the OS X partition and then you'll need to use the Online internet Recovery system to repartition your drive as One Partition to remove the FUBAR you have created. Then once that ios done restore your Mac from the Time Machine backup you created.
You can then use Boot Camp Assistant to recreate the Windows partition and reinstall Windows. Then do NOT try to make any other partitions in Windows or OS X.

Can i have my windows partition on an external drive?

hello all,
alright, so im looking at a laptop for college and after much research and a few trips to the apple store i want the new, 13-inch macbook pro, with retina display and a 256GB flash hard drive. i love this computer in every aspect except.... you guessed it, its small hard drive. i can always get external drives to make up the differance though, and their is always the cloud so i dont think ill have too much of a problem. but i do need to use some software for college that is only windows based. so rather then splitting up this already small hard drive can i just install windows onto my mac (because i already know i cant put windows on an external drive with boot camp) and make the entire windows partition on the external drive? this way im not losing any native space besides that used to hold windows and im not installing windows to an external drive so hopefully bootcamp wont have a hissey fit. can anyone tell me if this will work? or if this wont work can anyone give me any other solutions to having windows on my mac without splitting up my native hard drive? such as installing windows to my mac and making the partition in the cloud or something? just anything so i dont have to split my already small, yet extremally fast, 256GB hard drive.

You can install Windows on your internal drive and store your Windows data on any drive you want to use. Keep in mind that any Windows programs you install in Windows will be installed on your internal drive. So make the Boot Camp partition large enough for Windows and any programs you may install now or in the future. You will also need room for swap/page files and other activities such as installing Windows updates.
100GB will likely be a good size for the Boot Camp partition given that it is unknown what programs you will be installing.

If i create a partition for Windows 7, and boot up in Windows using Boot Camp, can I still access the files from the Mac partition (Photo's Music etc.)

Ok Great,
Will installing Boot Camp drivers allow me to both read and write to the OS X Volume from windows?
This is important as if it will it means i can make the windows partition a lot smaller and keep all my files on the OS X partition which would be preferable.

No, OSX will be read only (from Windows) and vice versa. (you can install 3rd party utilities on either or both partitions, to make read/write possible)

Can I partition a 3tb fusion drive on a 2014 imac27", with boot camp, to let me install windows 7?

I have used boot camp to create a partition for Windows 7 on 3 earlier Macs (iMac 24" 2007 / Mac Pro 2009 / Macbook Pro 2009) as well as a recent Macbook Air 2012.
My main reason for this is to use Sage Account/Payroll, and also a couple of other Windows-specific programs.
I have just replaced the old iMac with a new iMac27", with a 3tb fusion drive, and want to partition it to install a new oem copy of Win 7 sp1.
However, I found an article on this (link: http://twocanoes.com/winclone/support/installing-windows-on-a-boot-camp-partitio n-on-a-3-tb-fusion-drive) implying this might not currently be officially supported by Apple & boot camp assistant, and providing a workaround procedure to create 3 partitions. The article begins with this note: "Important Note: This help document is for reference only, superceded by updates to OS X that include support for 3TB drives and Fusion drive in Boot Camp Assistant. Use Boot Camp Assistant to create the Boot Camp partition."
I have two questions:
1 - Can anyone advise if updates have now been made, to provide this support for partitioning the 3tb fusion drive?....and if not, is this likely to change soon?
2 - If this is still not officially supported, can anyone advise if they have successfully created a Windows partition on the 3tb fusion drive & installed Win 7?
Thanks in advance.

Based on Apple's knowledge base. this configuration is supported for Windows 7 x64 and 8 using Mountain Lion 108.3 or higher. Simply use BootCamp Assistant to set it up.

For your application, you might also consider virtualization software like VMWare Fusion or Parallels.
I use both BootCamp and VMWare Fusion. Fusion is much easier to install, more flxible, runs at the same time as your Mac applications etc. For typical applications, there is no notable performance degradation.
If you need high performance graphics for gaming, BootCamp is still the best way to go. For all other applications, I prefer VMWare.

I started Boot Camp on a MAC mini but then had a power failure after 30 secs :( Now when I start Boot Camp the option to install Windows 7 is gone. In it's place is Remove Windows 7. It seems to hang at Partitioning disk Can I recover?

Welcome to the Apple Support Communities
That's because the Boot Camp volume was created, but your Mac hasn't been set up to start automatically from the Windows disc. Insert the Windows DVD and press C key while your Mac is starting to start Windows installation.
If you want to make sure that everything is correct, open Boot Camp Assistant and choose the option to remove Windows 7. Then, open that application again, select the option to install Windows 7 and you will be able to install Windows as usual

I'm trying to create a Windows partition using Boot Camp. An error comes up telling me that I need to reformat my current partition(s) into one single partition. However, it's already formatted in the correct format, and is already a single partition.

As made clear in the title:
I'm trying to create a Windows partition using Boot Camp. An error comes up telling me that I need to reformat my current partition(s) into one single partition. However, it's already formatted in the correct format, and is already a single partition.
My computer recently had a kernel panic, which apparently the corruption was in the system and needed to be erased and re-installed. I have a complete back-up using an external hard drive, and I am definitely not willing to do another one of those to reformat a partition that is already singular. I restarted the computer after ejecting my back-up, and after turning off time machine (thinking that boot camp was recognizing it as a secondary partition), however the error still occurs.
Is there any way to get around this?

/dev/disk1 on /Volumes/Windows7 (udf, local, nodev, nosuid, read-only, noowners)
From my very basic knowledge - it still looks as if there is only one partition (not including the windows 7 CD necessary to install the windows partition).
