Extend system partition for upgrading to Server 2008

Nanday Watt

April 1, 2011
I have a Dell Poweredge 800 server with three hard drives (hardware RAID) that is running server 2003 standard edition. I want to upgrade to server 2008 but the C drive, which is the system drive, is only 12GB and it needs to be at least 16GB to do an upgrade. I would like to resize it to 50 gig. I am glad to find Partition Assistant Server Edition, the software helped me resize this drive. Very cool technologies!

Succeeded in extending a Server Partition, exciting

I just ordered the Unlimited version and I need to extend a C partition on a Windows 2003 Standard R2 server with a dynamic disk. With your help, I converted the dynamic disk to basic disk with a Dynamic disk converter, then expanding the C: partition took 6 hours, may be too large amount of data, and finally succeeded! I’m very excited, thank you for your kindly help!
