Aug 26, 2013 4:54 PM in response to Darbyqby Kappy,★HelpfulThe problem:
- You are asking for more contiguous space than is available on the drive.
- The drive is highly fragmented.
Here's what you need to do:
Request a smaller Windows partition. If that isn't feasible then do the following:
Cheap and Easy Defragmentation
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.
1. Get an empty external hard drive and clone your internal drive to the
external one.
2. Boot from the external hard drive.
3. Erase the internal hard drive.
4. Restore the external clone to the internal hard drive.
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. 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 upward pointing arrow button.
After startup do the following:
Erase internal hard drive
1. Open Disk Utility in your Utilities folder.
2. 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.
3. 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.
Restore the clone to the internal hard drive
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. 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.

Aug 26, 2013 5:00 PM in response to Kappyby Darbyq,I don't have a readily available external hard drive to defrag with, is it possible to just erase the drive and start fresh?
I've already backed up the few files I need to save and the rest are applications I can reinstall easily.

Aug 26, 2013 5:13 PM in response to Darbyqby Kappy,★HelpfulYes, you can do that if you don't mind losing all your data or already have backups and can update the backups before you erase the drive. You would do the following:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
Note that the above only erases the OS X volume. It does not repartition the drive which is something you cannot do using Lion.
If your computer came originally with Snow Leopard on the installer DVDs, then you can repartition the drive using the Snow Leopard DVD:
Drive Partition and Format
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select your 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.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
Update the Snow Leopard system by downloading and installing Mac OS X 10.6.8 Update Combo v1.1. You can now upgrade to Lion by re-downloading the Lion installer from the App Store. Look for it on your Purchases page.

Aug 26, 2013 5:21 PM in response to Kappyby Darbyq,My system came with Lion installed, can I still re-install from my purchases in the app store anyway?
-
Aug 26, 2013 5:29 PM in response to Darbyqby Kappy,Yes, you can. Your system should be fixed by simply erasing and reinstalling Lion:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears.

Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

I've come across this problem myself, so I attempted this procedure, although I receive an input/output error when trying restore my internal hdd to my external. I have never a problem with either. Could I instead create an image using DU and save it to the external drive then extract that image to my internal drive later? If so, is there any additional steps I need to take?
