Need to resize "C" partition

Server has 12 gig on C drive, and 125 on  D.  I need to expand the C drive to about 25.  Windows updates, etc. have bloated and we have less that 1 gig left.
Thanks for help.

You might want to use some system backup application such as acronis or ghosting software. Do a backup and recover it to a bigger HDD space.

Hope information helps.

Hi kgallbreth,

This is a tough one. You'll need something like Partition Magic, I don't think the standard edition will let you resize a server disk, you will need the Enterprise edition, I think.

Personally, I would backup, format and restore...

To free up more space check to see if the pagefile.sys file is on the C:\ or D:\ drive. If on C:\ move to D:\. That should free up some hard drive space. Also look for *.dmp files to delete.

The best way to do this would be to use a software package like Partition Magic or GParted ( ). I recommend GParted because I have used it many times and that it is totally free. Before you proceed please backup your data just in case - I have never lost data before doing this, but it is better to be safe than sorry. Burn the disk and boot off of it. You can then follow these instructions to resize the drives:
 I hope this helps. Good luck.

I agree with oks1977.  Ghost or a utility like it will be the fastest and safest way to do this.  Not only will it work, it will make a backup while doing the imaging to protect your data.

No matter what way you do this, follow andrew_aj1's good advice and be sure to get a good backup before you do anything.  Just the act of making a backup will reduce the 'karmic chance' that anything will go wrong during the operation.

Good Luck,

Hi Ken:
12 GB is plenty for an OS partition:

Check out this article and tell me what you think:

As chief states that article is perfect.  I want to add resizing your boot partition is extremely risky and if it fails down goes your OS
I have resized a boot partition many times without issues, but as I stated always backup your data before you do just to be safe. You should have no issues with GParted as long as you take your time and follow the instructions.
Good luck.
To support andrew_aj1, GParted has worked great for me as well.

Simple.   Download the free demo version of Boot-It NG (, which is an exceptionally good partition management tool (Well worth buying and keeping in your "toolbox"); and use it to do the following:

(1)  Resize D: to free up some space
(2)  "Slide" D: to put the free space adjacent to C:
(3)  Resize C:

Done :-)    You can use this technique to make C: as large as you want.

Here's a bit more detail on the process:

Note:   Since you only need to use Boot-It to do the operations I listed above, you don't need to install it on the hard drive.

After you create a bootable CD (or floppy), just do the following:

Boot;  select CANCEL; then OK.   Click on Partition Work.   You'll now "see" the partitions you need to work on.   Just highlight the 2nd one (this is D:); then click on ReSize ... wait for it to complete;  then "Slide" it (putting 0 free space after so all the newly freed space is before it);  then highlight the 1st partition (this is C:); click on ReSize, and add all of the free space to it.

The two ReSize operations will be very quick (especially for C:).   The Slide will take a while.  (it's got to move all of the data in D:)
I also can vouch for garycase's post using bootitng.  It really works too.  But even if you already do backups, Get A Backup First!
