We found the solution for Windows XP Disk partition issue.
In the provisioning template under Post OS installation mode it needs some time to do the extended partition. So what we have done is just we have added one more task called "Wait for some time before extend the partition" in that we have given 60 seconds to wait, then we have added the extended partition (Disk 0, partition ID 2 and size “0”)
Now it has resolved our problem :-)
Great Thanks a lot for the solo effort
