I can't expand BOOT/OS C DRIVE on Win 2003 Server on VM

I have tried Partition Magic and Easeus and it won't let me expand the C Drive.

Currently the C Drive is 12G.
I gave the VM 8G more in reserve to make the C Drive become 20G.
The OS recognizes the 8G as unallocated space but it won't let me expand the C Drive.

Experts please help.

Thank you in advance.

How to Resize a Partition after Disk Expansion

To re-size a disk, select the Virtual Machine, Select Edit Settings, Highlight the Virtual Hard Disk, and select Edit
there is an option to increase size. This only changes the physical size of the virtual disk, it does not grow the partition on the disk. See below.

Before making any changes to the partition structure of the disk, ensure you have a full backup, not a snapshot.

1. Resize partition with Gparted Live CDROM

i. Download Gparted Live CDROM (http://gparted.sourceforge.net/livecd.php).

ii. Upload the cdrom iso to the vSphere ESX/ESXi datastore.

iii. Mount the cdrom or iso on the virtual machine.

iv. Shutdown and restart the virtual machine booting from the cdrom.

v. Select Resize partition.

Here is a Tutorial Walkthorugh of how to resize a partition with a GParted Live CDROM



2. Using DISKPART.exe

(the system disk cannot be re-sized within the virtual machine, but other disks can be resized, eg. D: E: etc

i. Shutdown the virtual machine.
ii. Remove disks from virtual machine (but do not delete them).
iii. Add the disks to another virtual machine.
iv. Start up virtual machine.
v. Use Diskpart in the OS to extend disks.

see here for details on Diskpart usage


3.Use VMware Converter Standalone to complete a V2V (virtual to virtual conversion).
there is an option to increase or decrease the size of target disks on the desintation at conversion.

Hello and thank you.

So with option 3 - "VMware Converter Standalone", I CAN resize the C Drive ( OS / Boot ) ?
Seems the simplest of the three.

Yes Option2 - "Diskpart" did not let me resize the c Drive.

Yes, VMware Converter, can resize the disk, resize the OS partition, in one wizard based procedure, leaving you with the original VM as a rollback, its easy to use, and its FREE, and the VMware supported method to complete.
