Here is How I Re-Sized Win7 Bootcamp - No reinstall of Win7 needed!
I've been using Bcamp many years and done this several ways... this was by far the easiest and worked fine for me.
-basically I used newest WinClone in MacOS to create a Backup Image of my Bootcamp Win7 partition
-this is NOT necessary, but of course recommended in case something goes wrong, also makes sense to have a good image backup
-Winclone took about 8hrs to make a image (400g) to my external WD passport usb drive with a Mac HPFS partition on it for the backup file
-then went to Mac OS and shrink the Mac part down about 50gig
-then go to Win7, get free app MiniTool Partition Wizard Home Edition v7.1
-with this simply increased the Win7 part to use the now unallocated space
-had to use this tool since the area was to left of Win7 part
-this needed to reboot and run, it took about 10-15 min to run
-now Win7 part is 50g bigger and Mac is 50g smaller all is running fine
-ran a chk disk on win to be sure - took about 10 min and all is ok...

**** Here are my more detailed notes on this ***
Mike_Notebook_DisasterRecovery.txt
***** 03/19/12 working on Mac2 made new backup of Win7 partition and resized to get more space *****
-when done BootCamp partition is now 420gig in size
-also now have backup of Win7 image on WD USB drive "Mac2Win7-WinClone031912.winclone"
1. installed / run new version of WinClone 3.0
-run Win7 Chk Disk
-restart Mac2 - hold Option key - boot to Mac OS
-downloaded from
http://www.twocanoes.com 19.95
-I downloaded in Win7 and burned to a CD
-have to make sure installed as a Application - when first comes up with install screen have to drag the Winclone app icon
over to the Application icon in the application screen - kind of a visual install dialog box on screen
-now the app should be in the Finder - File finder - Applicaitons - listed here and started here
-don't want to run from a CD...
-I had tried to run from CD but it would refuse to work because of security errors and running from a write protected media
-so once I copied from CD to Desktop and ran the install dialog to applications it was OK, but has to be installed, not just copied
or run from desktop or CD - this is just the install program dialog box
-connected WD external Hdd Passport to USB port
-first had to use Mac Disk utitity to create a Mac HPFS partition on the usb drive, this is needed to save the image to
-Applications - Utilities - Disk Utility - selected the USB drive - used partition tool to resize and divide the drive to 375g Mac, 375g Win
-now can save the BootCamp Win7 image to the Mac HPFS partition with WinClone
-ran WinClone to make a clone backup of Win7 BootCamp partition
-was saved to WD USB drive "Mac2Win7-WinClone031912.winclone"
-this took about 10hrs to run (400gig+)
--- I tried to use CampTune X to resize partitions - it ran all night and just locked up, tried twice not work as needed
2. Shrink size of Mac partition from 100gig down to 50gig
-boot to Mac OS
-Applications - Utilities - Disk Utility
-Select the Mac Partition - Shrink - type in new size 50gig - apply
-did see warning about the Bootcamp partition but we NOT mess with this here at all
-Now Mac partition is smaller leaving empty "unallocated" space between the Mac and BootCamp Win7 partitions
3. Increase size of BootCamp Win7 partition to use "unallocated space"
-boot to Win7
-downloaded Free copy of MiniTool Partition Wizard Home Edition v7.1
-this version is free from
http://www.PartitionWizard.com
-once installed - run Partition Wizard
-selected the BootCamp partition - Resize - drag slider to left to get ALL now Unallocated space
-then OK
-now go to upper right and click Apply
-it had to restart the Computer - and then did the resize on boot up ins it's own app running before win7 boot
-this took about 10 min to run
-now booted to Win7 and all is ok - Win7 partition is increased in size
4. Ran ChkDisk on partition to be sure all ok
-Control Panel - Admin tools - Computer Mgmt - Disk Mgmt - Rt clk Select partition - Properties - Tools - Error Chking Check Now
-it will schedule a chkdisk on reboot
-reboot system
-Chk Disk runs on boot - takes about 10 min - all was OK
