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

- 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

How to back up Boot Camp and how to resize FAT partitions

I suppose someone has already addressed this topic herein, but in case someone needs help I am leaving with you what I learned.
I started with a partition sized to 18 gigs and installed Windows XP on it. Soon the drive became full after I installed software and various disc images so I can play games. I wanted to resize the partition to 28 gigs without losing my data, leaving 46 gigs on my Mac partition.
I was not sure what would work so I chose several methods of possible restoration. The easiest was to boot to the Mac and use Disk Utility to make a Disk Image of Boot Camp. The next precaution I took was to back up my settings with the Windows Files and Settings Wizard. Lastly, I booted to Mac and turned on viewing of hidden files. Then I copied all the files off the Windows XP partition onto an external drive. I also tried Acronis True Image while in Windows but it was not compatible.
I also discovered a free program called Winclone (http://www.tuaw.com) that makes an image of the Windows partition and restores it for you, much like Disk Utility works.
In OSX, I ran Boot Camp Assistant again to rejoin the partitions. Then I ran it again to partition the new drive to 28 gigs.
The first thing I tried to do was to use Winclone to restore the Winclone image. That failed with errors. Then I tried to use Disk Utility to restore the drive and Disk Utility would not allow me to restore the disk image onto the drive. I am not sure why Apple is so unsupportive of implementing their Disk Imaging technology within the context of their own self-created Boot Camp technology.
Anyway, the last thing I could try was to copy the files back onto the new partition or to give up and reinstall Windows and use Files and Settings Transfer Wizard to restore my Windows settings.
After partitioning the drive with Boot Camp Assistant, I copied the files over and rebooted. Windows said there was an unsupported drive. Then I realized that I missed a step in the installation instructions provided by Apple for Boot Camp. I forgot to format the drive again using the Windows XP install CD, that the Apple says is necessary.
So I booted up the Windows cd and erased the Boot Camp partition and made it a FAT drive so that I would be able to copy my files over to it from OSX, which I would not have been able to do had the drive been formatted as NTFS.
As XP started to install its software, and it started to copy files from the cd, I pressed the power button to shut down the Mac. (Do this at your own risk. I am warning you that this could damage your computer, so do NOT try this if you feel uneasy about it.)
I booted into OSX. Then I trashed the few files that Windows had started to install on the Boot Camp drive. Then I copied all my backup files back onto the partition.
Here is a widget that will allow you to view hidden files in OSX: http://www.apple.com/downloads/dashboard/developer/hiddenfiles.html
I rebooted the Mac and held down the Option key while restarting. When the Mac and Windows drives appeared at the startup screen, I selected Windows, which booted up successfully. It then recognized the partitioned drive as new hardware and required me to restart, which I did.
I wanted to convert my drive from a FAT drive to a NTFS-formatted drive.
This is how I did that:
http://technet.microsoft.com/en-us/library/bb456984(TechNet.10).aspx
After converting Boot Camp to NTFS file system I noticed an immediate speed increase in Windows XP. I
In conclusion, Disk Utility is a good method of backing up your partition, as it allows you to use a password to make a disk image of your drive. It also allows you to copy the files off the disk image onto the Windows partition. But it would be a lot simpler if Apple allowed them to use Disk Utility to restore the whole image back onto Boot Camp.
Other methodologies I did not get to explore because I am happy with my results:

After copying your files back to the Boot Camp partition you may get this error message when you boot up Windows XP. Notepad opens with this message "[.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\System32\Shell32.dll,-21787". If this happens to you please see this article from Microsoft. I had to perform both Methods 1 and 2 to remove the messages. http://support.microsoft.com/kb/330132

Failed Boot Camp Install during Windows portion - how eject Windows CD?

New iMac owner (intel, 24"). I tried to set up boot camp. I set the partion to 32mb. Then loaded a new Windows XP Home (with SP2). The Windows install crashed (blue screen of death) and my only option was to power off iMac. Now every time I turn it on, it tries to load Windows. How do I get Windows CD out of the superdrive?

Hi,
I am so glad I found your post. I tried to install Windows XP with BootCamp and was not successful. Anyway, I'm on a MacBook Pro with no no left mouse button. How do I eject the disk?
Also, can I shut down the MacBook with the error message "Press Ctrl-Alt-Del" to restart showing? I tried plugging in a keyboard but it did not work.
I see that you are in Germany and it is about 2:00AM there, so unless anyone else sees this message, I'm going to have to power down my laptop and see what happens.
Thanks!

Failed Boot Camp Install of Vista 32 has broken one of my RAID arrays

Attempted to install Windows through Boot Camp on my Mac Pro, I have a RocketRaid 2320 controller card, RAID was built through Disk Utility. No redundancy, I built 2 separate 1.8TB RAIDs (4 x 500MB drives) in each of 2 separate cabinets. Windows install attempt brought up the HighPoint BIOS, then failed to install Windows and I got the well-known "Select CD-ROM boot type" message. Now, one of the 2 RAID arrays appears to be broken. Disk Utility still sees all 4 drives, but only recognizes 3 of them as a RAID slice with a GUID Partition Table. The other shows up as "disk5s1" with a Master Boot Record as the partition map scheme. While much of what was on this array was redundant with the second, I have a lot of work that was only on this one, so any help in how to fix and/or reconnect the drives of this array would be incredibly appreciated!

1. I remembered RocketRaid 2320 don't provide EFI64bit from Highpoint website so you can't set boot camp.
2. Does your Highpoint raid management utility(Highpoint engineer also called WebGui)
provide any message for your broken raid?I am also a Highpoint user, I give you some suggestion:
A.(1)If your WegGui in Manage--Array show your broken raid status is "Critical"and your bad HDD, please replace bad HDD then select Maintenance items of upper right corner of the page
(2)This will open the Array Information dialog box, select Add disk button to choose the replaced HDD then press "Submit", you can rebuild your RAID array.
B.(1)If your WegGui in Manage--Array show your broken raid status "Disable", you just can use one of Webgui function--"Keep old Data"(But it still have high risks to lose your data, it is the final method to use, I suggest you try the A method best.)
(2) Select "Maintenance" items of upper right corner of the page, from the "Array Information" dialog box, select "Delete" button, and prompted a warning: the array of data will be deleted whether to continue, choose OK..
(3)Back to Manage--Array page, this time the array has been deleted, double-click the "Create Array"
button to display the page to create the disk. From the Initialization Method field select “Keep old Data”, the remaining arrays in strict accordance with the original set of parameters, the required attention parameters include: Number of RAID member disk, Array Type, Block Size, Sector Size.
(4)Click "Create", the initialization process will start automatically, RAID
recovery complete, prompts to create a successful, choose OK.
(5)See your volume in Mac Disk Utility if your data is recoveryed

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.

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.

Should my boot camp install see my OSX drives?

HI folks. I"m trying to run Windows 7 under boot camp and thought that a Windows boot camp install could see my mac partitions so I could access the same data when I boot to my mac or my windows 7 boot camp partition. They are formatted OSX Extended Journaled. Should I be able to see them? Thanks.

Windows 7 uses a NTFS formatted file system. OSx uses a Mac only file system, so the answer is you can't without third party tools. Search these forums or search Google. Your question has been asked and answered in these forums several times. The search button is in the upper right of this page.
If you install Windows using a VM like Parallels or Fusion it is a little easier to share files between Windows and OSx.

If you have Lion installed, and run Boot Camp, it will create the boot flash for you, just followe the tutorial on screen. As far as I remember, this was not possible prior to Lion.

I have a copy of Windows 7, and I am trying to bring up Boot Camp on my MacBook with Snow Leopard. But my Snow Leopard install disk is too old for Windows 7, so attempted Boot Camp install of drivers fails.

I have hand-installed the NVidia graphics driver, and I have keyboard, minimal trackpad, and hardwire to internet all working. So the WIndows machine is usable. But I am hurting for wi-fi, better trackpad, and whatever else is delivered by Boot Camp. I can't use any of the Boot Camp upgrades because I do not have XP or Vista.

While we all have MacBooks in this forum not all of us use Boot Camp. There's a Boot Camp Support Community where everybody uses Boot Camp. You should also post this question there.

"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.

New Macbook Pro retina boot camp install issue - Windows 7

Trying to complete a boot camp install but can't get past creating a partition. I am able to download the windows drivers through boot camp, it burns them to a DVD, verifies the DVD (couldn't use CD-R as it kept saying burn failure after verifying files) and then takes me to the make a partition page. When i click install the partition, it pops up saying "can't find the installer disc" and wants me to put one in the super drive. What gives? I have that disc in the drive, also tried the Windows 7 disc and got the same error. So basically I can't create a partition to install windows 7 that I have.
Any thoughts?

The disk was from my other PC system, however it is an OEM upgrade disc. Maybe that is the problem but if that is the case why did it work when I installed it through VMware and it worked fine? The disc can be used as a self full install of windows 7. I have also it on another PC with no issues. Trying to convert to Mac finally but this is causing a hiccup.
The next question then is do I really need to go the boot camp way? I only need it to run quickbooks (need windows version for reasons) and a couple of other programs but thought it may run better as a boot camp install rather than VM plus I couldn't figure out how to reduce the size of the partition that VM installs, it takes too much space from me for no reason (60Gb).
Thanks for any input.

Cannot install Boot Camp 3.2 upgrade for Windows 7 64 bit

I recently installed Windows 7 64 bit on my macbook. I also installed Boot Camp 3.0.1 after Windows 7 installation, however, WiFi did not work. Therefore, I needed to upgrade to the latest Boot Camp 3.2. However, when I tried to install Boot Camp 3.2 upgrade for Windows 7 74 bit, I got an error message saying that I needed Boot Camp 3.1 installed first. I CANNOT find Boot Camp 3.1 upgrade for Windows 7 64 bit on Apple website at all. Can someone please help me on this? Is there a way to get the complete Boot Camp 3.2 package that can simply be installed on version 3.0.1??

here is the link to bootcamp 3.1 for windows 7 64 bit http://support.apple.com/kb/DL1336 .. and no there is no package that can be applied to the windows side to go from 3.0.1 to 3.2

Snow Leopard Boot Camp Install Woes

I'm having some trouble installing boot camp. I have a MBP 2.2 and I have just installed OS 10.6 and I am trying to reinstall my boot camp partition. I am using an HP external USB DVD drive (which has been used to installed boot camp successfully in the past and is what I used to install SL). Anyway, 10.6 installs with no problems and then I am able to use boot camp assistant to set up the partition and the computer restarts. Then the disc attempts to spin up (I am trying with both Windows 7 32-bit and Windows XP... both discs have been used successfully in other situations) and then the screen usually stays grey/blank. Sometimes I can hold option and I get the HDD icon and it hangs. If I disconnect the drive and start the computer I get the apple icon and then it flashes a circle with a line through it and goes no further. Does anyone have any ideas? I am pretty sure the drive and the discs are good because I have used them to install windows on other macs with no problems.

I've also got this problem, after upgrading to Snow Leopard I couldn't access my windows partition anymore, the startup screen would hang after clicking the arrow under Windows HD. We removed it with Boot Camp Assistant and now when we try and re-install Windows (XP), the installations progresses until it hangs on a grey screen (we don't make it to BIOS) and we have to restart.
Additionally after the installation attempt, we can't get past the grey screen of death on startup (we get the startup noise - no apple logo) and have to use reset my Mac's PRAM and NVRAM to progress.
Also, after going through this process a Boot Camp disk image is created but it's empty.
Disk utility isn't detecting any problems. Could we have removed the partition incorrectly and something is jarring the process?

Boot camp is getting stuck while windows support software

I am using macbook air and currently trying to install windows 7 using bootcamp 5. The bar is stuck and is not progressing further no matter for how much long i keep it. Can anybody guide me on what might be wrong

Thanks for the note. But neither link lists our MacBook Pro mid 2014.
And how can I use Boot Camp Assistant to write the Windows.iso to USB-stick because it forces the download of support software (it is selected and grayed out).
The following page recommends using BCA for the MBP mid 2014.
https://support.apple.com/en-us/HT204048
I guess I could write the Windows.iso to USB using Windows (in fact I already did and it boots the MBP) and then try if the aforementioned software packages (which one?) contain necessary drivers for our MBP.
But I'd rather do it the recommended way letting the Boot Camp Assistant do the dirty work.
