Boot Camp Assistant / Disk Utility Stuck during Partitioning

Hello Apple / Apple customers,
I have a 15" MacBook Pro (Mid-2010) with a 320GB hard drive. I recently partitioned my hard drive to install Windows 7 in order to install and play a Windows game. Everything installed fine, but I discovered that I didn't have enough space partitioned to fit the game (I did not anticipate it taking 14 GB to install). So I deleted the partition. Now I'm attempting to make a larger partition and restore a Winclone image that I made of the previous partition on that new partition. The problem I am receiving occurs when I attempt to make a new partition in both Boot Camp Assistant and Disk Utility. During the partitioning process, Boot Camp Assistant stalls at about 30% and stays that way for hours, and Disk Utility also stalls during the "shrinking disk" part at about 30% as well. Is there anyway that I can fix this? I already tried repairing my hard drive by running Disk Utility via the Installation Disc, and it says that my hard drive is fine. Thanks in advance for the help.

Reinstall Leopard, but first use the Leopard install DVD Disk Utility to reformat the HD to one partition. See:
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh14.html
It's for Tiger, but applies for Leopard as well.

Boot Camp Assistant & Disk Utility First Aid failing?

Hi,
I am trying to open my download of 3DS Max for an assignment but the following problems are stopping me:
1. The message ' The document "Autodesk_3ds_Max_Design_2012_English_Win_32-64bit" could not be opened. The file is too large'
2. After advice on this forum I tried to create a partition with Boot Camp Assistant (of 32gb). But this failed and told me to repair the disk with Disk Utility.
3. Disk Utility gives the following messages after I have tried repairing and also verifying the disk
Would really appreciate some help!
Thanks

Cannot read partition created by Boot Camp in Disk Utility

Ok, so in trying to get a larger Boot Camp drive, I used disk utility to make a back up og my previous drive onto USB, and then removed the Boot Camp drive from OSX. This afternoon, I tried using Boot Camp Assistant to create a new partition to install windows onto, hoping to restore from the disk image on the USB drive.
HOWEVER, when restarting the computer when Boot Camp Asst. told me to, and it booted to WInXP sp2 disk, I can see 3 partitions on my drive. 1 partition being most of the 160g drive, 2nd partition being 116g of the mac drive, and the 35g of the 3rd partition (what I asked Boot camp to make) However, it doesn't say boot camp partition. I cannot install XP onto any of the partitions I see in the startup disk.
After spending nearly two hours on the phone with a very nice and helpful tech rep from Apple, my cell phone died, leaving us knowing that there is more space reportedly being used on my Mac HD than i have folders using space (only using about 73gigs of space before any of this partition work, now reports using 116 GB). I went back into the XP disk and deleted the 3rd partition, and now there is no gain in space on my Mac HD. We're re-verified and repaired disk permissions, and used the Leopard disk to repair the disk itself. Restored from Time Machine, and still no regained HD space.
Essentially I'm missing 35G of hard drive space now, and I can't install Windows.
I can only see the Mac HD partition on my hard drive. Anyone have a suggestion?!?!

Boot Camp Hangs, Disk Utility is very slow and gives an error.

Hello,
I would like to install Windows for some games.
But my problem is that when I try to make the boot camp partition it just freezes/hangs 50% in. I have repaired my Disk and it says it is OK.
Got a tip that I could resize my current partition to a smaller size then, make it bigger. This would help bootcamp, but it did not it just hangs around 50% again... I let it say over night, and when I woke up I got a error saying something like
"partition failed at checking archives".
Now I am lost, and do not know what the next step is, this is very annoying and not as easy as I imagned.
Hope you can guide me.

I assume this was the "slow boat to China" syndrome using TimeMachine over USB.
Sorry 'bout that, #1 before beginnng partitioning and the rest was "backup before beginning with Boot Camp Assistant"
Disk Utilty RESTORE is a clone style backup (or there are other programs but not on OS X DVD so you need to boot from something), and of course a different interface (eSATA wold be nice, so would TB or FW800) which should have cut it down to less than a day to backup.
60GB per hour and 500GB?

Boot Camp Assistant says Install rather than Partition

I have a second gen MacBook (Intel core 2 duo) I installed Windows XP via bootcamp back when I had OSX Tiger. Today, running OSX Lion, I deleted the windows partition with boot camp assistant, wanting to increase the hard drive size and install Windows 7. I successfully deleted the windows xp partition, and restarted the computer. Now I want to repartition the hard drive and install windows 7. I open boot camp assistant, click continue (only option) check 'install windows 7' and not 'download the latest windows support software from apple' as I already have this on an external hd and click continue. I choose the hard drive size, and boot camp assisnt has the option to 'install' and NOT 'partition'. I dont know why this occurs. anyway, if I click install, boot camp assistant says 'the installer disk could not be found' even though my windows 7 dvd is in the computer.
So, my question boils down to, 'why can't i partition my disk for windows 7?'
Any help would be greatly appreciated! Thanks!

After restoring, I lost my Recovery HD partition. I am currently working to get a new one. Perhaps I will install it AFTER boot camp is finished, which might solve the multiple-partitions error? I could use some advice here.
At this point, bootcamp is giving me a new error which says some files cannot be moved. I am moving this to a new discussion HERE:
http://discussions.apple.com/thread/3298756
Thanks for your help! Please respond to my new thread if you think you can contribute.

Same thing for me too. I have "downloaded the latest Windows support software from Apple" and put it on my USB stick.
Only if I try to disconnect the USB drive I get this message:
The installer disc could not be found.
Insert your Windows installer disc and wait a few seconds for the disc to be recognized.
Then if I connect the USB stick again, I get this message again:

Any tips on how to solve this would be greatly appreciated!

Disk Utility crashed during partition and DOUBLED partition use - now it's full?

This one has me stumped.
1TB Disk - NON-start-up - had about 450GB of data files on it.
Split it with disk partition so I could reclaim free space.
Disk Utility crashed during the partition.
Relaunched Disk Utility.
Now shows 900GB of the disk are used.
Tried to repair disk with Disk Utility, "Can't Unmount Disk"
Have rebooted now and am trying to find out WHAT that other 450GB of space taken up actually is. (using WhatSize).
Anyone have any clues what the heck is going on? I now no longer have any space to duplicate the partiion files to (though on another drive completely). I can still access the files but not sure what that other space hog could be....?
Thanks anyone.

Techtool Pro was able to determine the directory structure was fubarred - repairing it corrected the structure to report the size correctly.

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.

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.

Boot Camp and Disk Utility giving Error for my Hard Drive Volume

When trying to partition my Hard Drive with Boot Camp, I get an error message after a while saying that it can't be partitioned because there is an error in the volume and that I should check it in Disk Utility. After running Verify Disk, it had told me that the file count was wrong and that I should repair my Disk. I have leopard installed, but only had access to a Tiger Install Disc, so after booting to that and apparently repairing successfully, I booted back onto my Hard Drive and ran Disk Utility's Verify Disk again. Now it said that my Volume Header needs minor repair. I still get the same message in Boot Camp. Running Verify and Repair Disk from the Tiger Install Disc tells me that everything is alright and the Hard Drive doesn' need repairing. I read on an Apple article that verifying a disk that's booted can produce inaccurate results, and that it shouldn't be worried about, but I can't install Windows because of this! What should I do?

Hi,
you have to boot from the Leopard OSX DVD in order to repair the Leopard OSX volume on your harddisk.
Using Disk Utility from an OSX version that is prior to the one you want to repair can indeed cause more errors than before.
So, search for the Leopard DVD.

Disk Utility froze during partition resize.

Hi, i have a 1tb western digital external hard Drive which i use to store all my media and backups.
I set the partition to 950gb for media and the other 50gb for time machine to use to backup. This 50gb got used up pretty quickly, So i went and opened disk utility, deleted the 50gb time machine partition and then resized the 950gb partiton to 900gb so i could have 100gb for time machine.
So my 950gb media partition had over 550gb worth of files so i knew it would take a good few hours to peform this task. so 6 hours later i came back to my imac to check the progress and saw that it was in the "shrinking" stage and the bar was at about 95% complete.
So the next time i checked my imac was when i woke up the next day, it has now been 24 hours since i started and the bar is still on 95% complete and in shrinking stage. I thought it would of been completed by now but i carried on waiting. after 48 hours of waiting and the bar still being on 95% i figured that the disk utility had obviously crashed so i had no choice but to force quit disk utility.
I had a feeling that this would of somehow messed my hardive up and oh look.. it has. When i click on my external hardrive now all i get is a finder window appear with no results and a little spinning loading bar in the bottom right corner of the finder window. Left it for 15 mins but it still didnt load anything.
I am now in the middle of a "Repair disk" operation but it has been 12 hours and the bar is stuck at about 75%.
Any other ideas on whats gone wrong and how i can fix it? i have alot of important files on that hard drive and thousands of pounds worth of media. I will not be happy if ive lost that due to a fault in mac OS X.
Thanks for your time.

Unfortunately West Digital external drives have a very poor track record with Macs. I would recommend replacing it with a higher quality drive, something like a OWC, Lacie, or G-Tech.
In addition putting your backup and additional storage on the same external HD is a recipe for disaster. The reason is very simple, if that drive dies (and all eventually do) you will lose both your data and backup! Here is a recent article from or Macworld that discusses backup strategies, while I think the author is a little over the top having redundant backups is a very wise idea. Because external HD's are relatively inexpensive there really isn't any reason not to.

Boot Camp Assistant says "The disk cannot be partitioned because some files cannot be moved." What can I do?

I am trying to install Windows 7 Ultimate on my MacBook Pro that runs OS X Lion. I have read through a lot of the other threads and I think I understand that the I need a clean, defragged part of the hard drive to do this on. Boot Camp Assistant tells me to "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." That's all good and everything, but I don't have any idea how to do that. I don't want to risk losing any of my data and I don't want to download any "freeware" to try and help me accomplish this task. I would like a step by step guide on how to make this work. Also, is there anyway that I could have prevented this error? I don't understand why Boot Camp Assistant is even on my MacBook Pro if everyone that uses it will get the same error. I have done nothing but taken it out of the box and started using the Apple software that came installed on it. If there is not a simple way to do this in the Disc Utility, then I don't want to do it at all. I really don't like the idea of putting all my data on an external hard drive just to have this done.

Just installing OS updates and programs will
Write the installer
Uncompress the file at say 7x and write the actual installer in a free area that often may be anywhere but at the far end of the partition is common.
Write new version or copy of the files being changed/updated (myfile.new and myfile.old)
Delete the entry in the directory for the temp files and versions.
A program that can show your hard drive and where files are and where free space is, and show fragments.
OS X tries to eliminate small files with fragments when they are rewritten and when it can find contiguous free space to write the new file.
That can actually work against you, as it might fragment the free space also.
When a drive gets down to 20% free space there is a performance hit, you are using slower areas of the drive (inner tracks are usually 50% slower) and having more trouble finding filles and where to write files.
Clone Mac OS is one of the easiest and safest methods.
Click on source (Mac Harddrive), click on or drop the backup partition / drive into target icon.
Click "Run"
you end up with bootable (test it to be certain) exact copy.
Unplujg and keep it on a shelf
Update it before you inistall a new version etc of OS X or make changes.
Have two: one safe on the shelf from Week #1 and new Week #2
Disk Utility can do that.
With huge hard drives free space should not be an issue. The lack of a feature to defrag as part of Boot Camp or Disk Utility is why there are iDefrag and others, but they are slow and best run from.... a 2nd hard drive running OS X rather than from CD. and never great idea to do w/o backups or on live system.

Boot camp assistant ignores legit disks if the boot disk has a raid slice

I don't know if this is the right place to post... sorry if not.
Here's my setup:
disk0
Mac OSX HD
OS Share
Mirror (RAID slice)
disk1
Mac Fast
Windows Fast
Mirror (RAID slice)
disk2
Time Machine (one big Journaled HFS+ partition, that's it)
I wanted to use the assistant to make a new BOOTCAMP partition on disk2, but it never let me get past the opening screen because the startup disk had been partitioned outside of the assistant (true, it was) and was not a single Journaled HFS+ partition (also true). But disk2 is perfectly ripe for the, uh, boot camping.
I got rid of the RAID completely, and the assistant was happy to let me create the BOOTCAMP partition on disk2. After I got that working, I went back and re-created the RAID on disks 0 and 1. Everything works perfectly now.
Was I doing something wrong, or is this just a (subtle) bug in the Boot Camp Assistant?

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 Assistant hangs at partitioning process?

Hello,
I'm trying to install Windows on my Mac Pro. But when I run the Boot Camp assistant and assign the Windows partition, the Boot Camp Assistant hangs at the process of partitioning. The progress bar just keeps on moving, but it wont finish the partitioning.
Screencap link: www.laspalmas.nu/hang.jpg
Sorry, the OS language is in finnish but "Osioidaan levyä..." = "Disk partitioning..."
Does anyone have advice, why does this endless hang happen at this point?
Thanks for the replies,
Lauri

BACKUP before you start.
Repair your drive.
Would help to know how much of the free space is actually in a large enough unfragmented single chunk.
You may need to backup / initialize / restore.
