but why need to extend system or boot partition? As applications continue to be installed into the Windows system, one day, suddenly you will find that the system and/or boot partition do not have enough free disk space, and when every time the system starts, Windows always prompts the following information:

You are running out of disk space on SYSTEM (C:), To free space on this drive by deleting old or unnecessary files, click here…

This time i will use Gparted (http://gparted.sourceforge.net) , one of best opensource tools available, With GParted you can resize, copy, and move partitions without data loss (**Again i warn you to do a proper backup before proceed**)

-)Load in the Gparted live CD into the CdRom/DVDRom and boot up directly using CDRom/DVDRom, you might need to change your server/pc boot order

Select Gparted Live and press Enter to continue.

Use default setting and  press enter to continue.

Use default setting to use US-English and press Enter to continue.

Use default setting and press Enter to continue.

Select which partition you want to increase/expand.

Click on “Partition” from the Menu and Click on “Resize or Move”

Before Rezising. Drag Bar accross to Max Size

After Resizing.

Click Apply.

-)Done

PS. If your Windows 2003 is running on Virtualization (VMware ,VMware ESX/i, Virtualbox, KVM) , these steps can be followed:

-)Turn off Windows 2003 VM

-)Increase Disk Allocation to the VM for example from 100GB to 150GB

-)Turn on your Windows 2003 VM and boot using Gparted CD/ISO file

-)Follow the above steps before this “PS” section

[ Once Again , do this on your own risk, do backup first before proceed.]
