Keep in mind, before doing the task, always take backups for ur necessary data for safe guard.
Ur best bet is to use “DiskPart” utility which is built-in with XP. The procedure is narrated by MShere
AND if u feel troublesome, then don’t worry, simply use one of them like: ubcd4win OR use Knoppix live cd/dvd. They both have same capability to do ur job easily and of course they r free to use.
Once again I remind u keep in mind, before doing the task, always take backups for ur necessary data for safe guard.

i totally agree that you must do your backup 1st. do 1 or 2 backup to make sure the backup is really successful then only you do your diskpart.

You can use diskpart command line as Pdsathishkumar said or some third party software like Partition Assistant Home Edition which is free and safe.

it is quite easy to extend primary partition in XP now, there are several few partition software can help you, they are totally free of charge, but be sure to backup the important files before all operations. download the software here and follow the guide: http://www.partition-magic-free.com/
