How I resized a Windows partition

Moved from How Parallels "Desktop for Mac"

I successfully resized my Windows 2003 installation today using the following process.

Copy the HDD drive image file and rename
Use Image Tools to resize the original HDD file
Change your VM profile to boot off of the copied HDD image and add the original, resized image as a second hard disk
Once booted, open CMD prompt and run DISKPART
View volumes in DISKPART with the command list volume. Note which volume is your original, resized partition
Select that partition using the DISKPART command select volume # where # is the partition number.
Enter the command extend
Enter the command exit
Exit Windows and change the VM profile to once again boot from the original, resized image file. You can disconnect (and delete?) the copied image file from the VM profile.

I don't know if DISKPART can be used on Windows XP, etc. but I know that you can download it from Microsoft. Google diskpart windows download.

As mentioned, this worked for me though I cannot guarantee that this will work in all situations.

I can personally vouch for the fact that they work with Windows XP Pro Service Pack 2 I just went from 8gig to 20gig. Just some notes to help those that also want to do this. 1. When you do "List Volumns" you will be hit with 2 volumns that say the same size, so remember you've setup your backup copy as the boot so that will be the C: and you added your resized one and that will most likely be the E: (D: being the CD/DVD).

You'll need to use Image Tools to resize the hard drive image in step 2 of my original post

If this is found in the Configuration Editor, I'm not sure what to do. You guys must already be Windows saavy (or programming smart). Any help would be appreciated, thanks, Paul

When you first start Parallels Workstation, you'll see the property page for the current VM. If you click on "Hard Disk 1" under the resources section, you'll be shown the Configuration Editor page and "Hard Disk 1" will be highlighted. Under the "Image File" field on the right side of the screen, browse to and select the copied, renamed image file. That will make the copy the new boot drive.

Now, Click the Add... button at the bottom, left side of the screen. Choose "Hard Disk" then click Next. Choose "Use an existing hard disk image" then click Next. Browse to the original, resized image file then click Finish. Now, you'll see a "Hard Disk 2" entry on the left on the Configuration Editor page. Click OK to close the Configuration Editor window.

Start your VM and follow steps 4-8 in my original post.

Shutdown your Windows guest OS and wait for the VM property page to appear. Once it does, click on the Edit button to display the Configuration Editor again. Highlight "Hard Disk 2" then click Remove. Select "Hard Disk 1" and browse to and select the original, resized image file under the Image File field on the right side of the screen. Click OK to close the Configuration Editor window. Click Save to update your VM properties.

Restart your VM and you should see that your guest OS drive is now up to the size you reset it to.

Download the live cd from http://gparted.sourceforge.net/download.php Boot your VM from the live cd iso Select default values until gpartd starts Select partition to resize Resize and apply Disconnect iso Reboot Windows should run chkdsk automatically.

Perhaps, but resizing a partition I don't have a copy of seems unnecessarily risky, so I wouldn't advise not copying it first just in case something goes wrong.

Heh, how come I always feel like I'm the only one who runs a backup system?

So I found a workaround using Image Tools and gparted. My original disk image was 4GB resizable. Here's the steps I used: 1) Resize from 4GB to 10GB using Image Tools, keeping as resizable. 2) Boot into gparted. 3) Try to resize to partition to 10GB. BUT I got an error during the resizing operation. I assumed it was because of the resizable partition - still not sure. 4) Quit qparted and use Image Tools to convert the image from resizable to "plain" format (still 10GB). 5) Reboot into windows. Still showing C: as 4GB. Didn't work. 6) Boot again with qparted. Showed the partition was full 10GB, but with 7.5GB used instead of 1.5 GB used. 7) Resize partition to next smallest value available. This was successful. 8) Reboot back into Windows XP, and how I have 8GB free. I think the key was getting gparted to actually do the resize operation by slightly shrinking the partition size. This rewrote all the data and properly set the free space.

All,

This technique worked exactly as mentioned. I was able to expand a single 4 GB NTFS boot volume (C:\ drive) with about 250 MB of free space to 8 GB.

I extended the virtual hard drive file using the Parallels Image Tool to 8 GB (perhaps I could have used gparted to do this too), booted the VM to the mounted gparted 0.2.5 live CD ISO image and resized the original partition from 4 GB to 8 GB.

After restarting the VM (booting off the hard drive), Windows XP did a checkdisk, restarted, launched a dialog mentioning some device was found/changed (I suspect this step might not always happen to you), restarted and now I have an 8GB partition in a single virtual hard drive file.

I agree, this should be a FAQ entry or sticky topic!

Thanks Batman!
