Resize Windows Partition

How would I resize my partition for Windows? I had not expected as much updates for Windows to take place and underestimated the amount of space for my hard drive. Please help!

I'll probably give-up on waiting for a compatible Camptune X on ML, however all's not lost as Coriolis whom do both iDefrag and iPartition have confirmed in a rely email that iPartition can resize the Bootcamp partion.
There are apparently a few small things to bare in mind if using iPartition 3. Firstly it is recommended to check the NTFS filesystem for any errors beforehand (obviously a wise thing to do for any partition resizing program) and that you'll have to boot from iPartition running on external media, i.e. USB boot drive etc. This shouldn't be a problem for many as this is how Camptune use to work and I'm probably not confident of a partition re-sizing program that adjusts partitions on the very drive the system is booted into (although that would be a really cool and convenient feature if proven to be 100% safe with no known issues or repercussions - maybe an iPartition 4 might address that if OS X allows).
Additionally it is advised that virtual machines such as Parallels or VMWare apparently may need to be recreated, but I'm a little unclear on wether that simply means 1. re-adding the virtual machin image back to Parallels, OR, 2. copying the virual image over to an external drive and then back after partitioning-resizing has been done in order to just simply 'add' the virtual image back into Parallels, OR, 3. the more undesired concept that the virtual machine would have to be rebuilt from scratch, i.e. re-installing Windows/activation/updates etc. which is the same as simply running Bootcamp assistant and setting up Bootcamp all over again with the now desired partition size. I will have to check back with Coriolis on this, however they are very helpful and quick to answer.
That aside, iPartition 3 does look very impressive and can deal with virtually all disk related partitioning and formatting. I can't help feel that it is what Disk Utility should have been.
A word of caution; I recently used Paragon Hard Disk Manager 2012 Professional for resizing the Bootcamp partition and completely lost the 'GUID' format structure after which was not good. I ended up eventually reinstalling OS X and Bootcamp from scratch.

Resizing Windows Partition - No Longer Booting

Whenever I attempt to setup a Windows/Linux Dual boot I get hit with this same dilemma. I start off with a NTFS format partition with Windows XP on it. As soon as I resize the partition, it no longer boots. Even before installing linux/grub. I defragmented before attempting this, and I took every precaution. In the end, I'm never able to boot my Windows OS. I can boot Linux from the Grub menu, and I can still access my Windows files.
As of now I've reformatted back to Windows. I would just like to know what went wrong because I want to attempt another install later on.

Ward,
windows is weird in that it notes somewhere the block numbers where the system is installed, and when that moves
it does not boot anymore.
Now you are making life more complicated then necessary: if you still have windows resized and installed (and not booting),
you can use the windows install cd and go into repair mode. It will fix the resized windows.
If you are starting from scratch, before installing windows, start a Linux live CD, do not install it, start the program
"gparted" and partition your disk as you want it. Then install windows in one of the partitions.
Instead of the Linux live CD you can also use a Gparted stand alone CD:

How do i resize windows partition?

I am sorry if this sounds like a question that has been answered numerous times, but the answers I have read thus far have not helped me at all. I am more confused than ever and would appreciate anyone who can dumb this down so that I can spend the next few hours methodically: 1. resize the boot camp partition from 40GB to 80GB. 2. Install Windows 7 3. Get on with my life.
Now, the Windows side (NTFS) of my MAC Book Pro doesn't have much on it and I have backed up the documents to an external hard drive. The apps on it can be reinstalled if I have to. Since my Windows 7 is an upgrade to awful Vista, I guess I have to reinstall Vista before I can install 7. I have read about WinClone and quite frankly don't understand at all what to do. I want to know if it would not be simpler to remove all apps and docs from the windows side, then remove the partition completely and start anew? If so, does that mean that I would use disk utility in OS to partition the drive? OR do I start BootCamp, partition, then install Vista?
Thank you.

don't use disk utility to do anything with the windows partition. it should only be modified using bootcamp assistant.
if you don't care about keeping your current windows install you can do the following.
1. run bootcamp assistant and remove the bootcamp partition.
2. then run bootcamp assistant again to create a new bootcamp partition of the size you want.
3. from here you need to install windows 7 on the newly created empty bootcamp partition. if your windows 7 can only be installed over an existing vista install you'll have to install vista first.
I'm really not familiar with windows upgrade processes and I'm not sure if this is necessary. also, keep in mind that even though many people have installed windows 7 in bootcamp, it is not yet officially supported by apple. apple will release windows 7 drivers for bootcamp later this year

HT4818 how to resize windows partition

How do you resize the windows partition in boot camp?

iF you have already created the Windows partition, you can't resize it. To do it, you have to use an app like Paragon Camptune, that will allow you to resize your Windows volume > http://www.paragon-software.com/downloads/camptune.html
The other option is to delete Windows and create the new partition with the size you want in Windows. Make a backup of your data before doing this

Won't boot after resizing Windows partition

So I'm dual-booting Windows 7 with OSX using Boot Camp. The Windows partition had very little space left so I decided to go ahead and resize it. I first used Disk Utility inside OSX to shrink the size of the OSX partition. Worked like a beauty.
I then went into Windows and resized the Windows partition using Paragon's Partition Manager....big mistake.
I would gander a guess that in order to resize, the Paragon software has to reboot and boot into a partition it created. Which is all fine and good except I don't think (version 2010 of Partition Manager) the Mac bootup hardware likes this. Unfortunately, this seemed to have nuked my bootup of anything, including OSX.
Is there a way to recover/repair this without having to do wipe everything and reinstall?

Welcome to Apple Discussions,
You can boot to the Mac OS Install disk that came with the computer and run Disk Utility from from the disk to attempt to repair the Mac OS partition of the logical drive. If it can repair it then you may be able to boot.
Live partitioning is like doing open heart surgery on yourself. Its not a simple process. Doing it with a utility that isn't necessarily made for handling an HFS+ partition table (Like what the Mac OS uses) is tricker still.
Give Disk Utility a try. There are other directory repair programs out there (Drive Genius, Disk Warrior, etc.) that can do deeper levels of repair.
Were it my drive, I would probably just erase it and restore from backup (assuming you have all your data backed up and are confident that the backup is good). You don't want to keep working with a potentially damaged partition table. But thats just me.
Hope that helps.

Non destructively resize Windows partition

Is it possible to resize (expand) the windows partition without deleting the files on it? I have heard of iPartition, but I don't want to pay $50 for something I may only use once or twice.

Hi,
WinClone can do this http://twocanoes.com/winclone/
And in the WinClone FAQs https://www.twocanoes.com/forums/viewtopic.php?t=515 - Section "My current Windows partition is the wrong size, and I want to make it larger. How do I do this?" you find a how-to.

How to restore Windows boot after resizing system partition ?

I have an fairly new HP Pavilion 14-n228ca notebook which I intend to use mostly for Linux, but still wish to occasionally run the WIndows 8.1 that it shipped with.
I installed CentOS 6.5 using the dual-boot procedure I have used many times in the past with XP and Vista, viz. resize the main NTFS filesystem, delete the partition and recreate it smaller at the exact same start byte.
Normally (on XP,Vista) Windows boots from GRUB, but here I get an error "file \Boot\BCD - missing or contains errors"
F9 at boot gets me a hardware boot menu, where I have a choice of "OS boot manager", EFI file, or "notebook hard drive". The last gets me GRUB. The first drops me to a repair menu where I can try autorepair, which fails, or a command
line.
The command line allows me to run diskpart and assign a drive letter to the system partition, at which point I can run chkfs successfully and access files.
If I try "bootrec /rebuildbcd" it finds one valid volume at \\?\GLOBALROOT\Device\HardDiskVolume4\Windows but then says "system cannot find the file specified"
How can I restore the ability to boot the Windows partition, preferably without messing up the Linux one ?

assuming your recovery partition is still extant, you can run that and go back to factory

What do you recommend to resize a partition on Windows Server 2003 R2 Standard Edition SP2?

I am running Windows Server 2003 R2 Standard Edition SP2 and only have 2.74GB of hard drive space left on a 11.9 GB hard drive. My D:\ drive has 37.5GB of free space left on a 124GB Hard drive. I would like to know what software is
recommended to repartition drive size or another way to repartition drive.
Thanks

You just need to shrink partition D and get some unallocated space, and then you can extend the system drive with the Unallocated space. There is no need to delete or format partitions.
The most important is guarantee data security. I have such experience resizing partitions.
The partition tool required reboot to process, after a while power off in my office, I know the Server must be damaged. Later, when I turn it on, I cannot believe, it continue to process and reboot to desktop several minutes later. What a lucky man.

Hi, Ralph,
The problem is that I did erase the partition, using disk utility, but I can't go back to my original disk size pre-partition, as disk utility won't let me do it and gives the message "Couldn’t modify partition map because file system verification failed." When I try to use Boot Camp Assistant it won't let me select the third option to remove windows.

How do I delete a Windows partition and resize the MAC HD partition to orig

Resize windows 8 partition on OSX Yosemite

When I initially setup my Windows 8 partition through Bootcamp, I split my HD roughly in half. I've now come to realise that I don't need that much space on the Windows size, and require more on the Mac side (win for mac!).
I'd like to resize the Windows partition to make it smaller -- how do I do this?
Kind regards,
Jeremy

There are no Apple tools which support this. The Apple direction is explicit. From Boot Camp 5.1: Frequently asked questions - Apple Support
Can I resize the Windows partition after installing Windows?
No. Back up your important files, then use Boot Camp Assistant to delete the old partition and create a new one.
There are third-party commercial tools like Winclone and Camptune which do that. You may be able to Gparted, but I have not tested it.

Computer shut off while resizing my Windows partition

So, I was resizing my windows partition using gparted, like I often do, however, I stupidly decided to do it without plugging in my power supply for my macbook, and the computer ran out of battery while the resizing process was happening. Now, gparted states that dev/sda4, my windows partition, has an unknown filesystem, and my windows partition also doesn't show up in Mac OS X finder or the option-key menu at boot anymore, which leads me to believe that either the file system information or the boot information was lost when my computer shut down. Also, I was resizing my windows partition from 115 to 135gb, and gparted states that dev/sda4 is 135gb, so my computer probably shut off after the size-increasy part. I have two ideas of how to fix it at the moment. I have a Windows 8 installation disk that I can use as a repair disk, and I was also going to try using ntfsprogs in a Ubuntu live CD to see if that fixes it. However, since I'm too scared of losing my data before I accidentally overwrite anything, I decided to try and back up my important files, so I dried to mount it in Ubuntu. Strangely enough, when I ran fdisk in ubuntu, it stated that dev/sda4 was actually fat32 system instead of ntfs, and I have no idea why. I tried to mount dev/sda4 as both a fat32 system and a ntfs system, however, in both cases, terminal stated that dev/sda4 did not exist, even though it showed up in fdisk.
Anyone else accidentally shut off their system during partion resizing? There's probably different levels of severity based on where the process was, but I hope none of my personal files were deleted. I really don't mind if I have to erase my partition and reinstall Windows, (although I'd rather not) but I do want to find some way to mount the drive to back up my important files?

Disk utility resize mac partition resulted in 'no bootable disk' while starting from bootcamp windows partition

my macbook air had two partitions for Mac OS and Windows XP. Because XP partition is too small, I used disk utitility in Mac OS to shrink the Mac partition, and make a new FAT32 partition, which I expected to use it in windows. Till now, I can find three partitions in disk utitily, MacOS/FAT32(which is totally free)/Bootcamp(windows). And in system preference->boot disk, I can see both Mac OS X and Bootcamp Windows.
But when I reboot the computer and press "option" key while rebooting, I only see two boot device options, "mac os" and "recovery", no Bootcamp Windows.
Anybody can give me a hand to recover my previous windows and use the freed partition in windows? Thanks.

Hi Stefan!
I have a rather similar problem having a BootCamp Windows 8 Partition. I actually have 2 NTFS partitions for windows and 1 for Mac OS. The situation is:
0 - for Mac OS
1 - BootCamp windows (NTFS - boot) - 60GB
2 - Windows (NTFS) - 100GB
After updating to Maverick I have no idea why, but now I have:
in Mac OS:
0 - Mac OS
1 - BootCamp - 160G
In Windows:
0 - Mac OS
1 - BootCamp - 60GB
I have tried recovering the partition with a windows program, but all it could do is find it, but without any files on it.
How can I restore my partition table to the way it was?!
WHY did Mac OS mess up my windows partition table?
WHY didn't I get a warning that the Boot Table will get altered?!
Thank you for any help

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:
