Found an extra partition on Win XP, what is it?

I recently upgraded my win XP laptop and wanted to put dual-boot linux on it.  I used Gparted (Partition editor) to look at the 100GB hard drive.  There was the main NTFS C: partition, a much smaller HP recovery partition (D:) and an unlabeled 1GB NTFS partition.  The unlabeled partition contains files like boot_2G.ini and CLLauncher.exe.  Is this  a malware partition?

 

If this should be on another discussion forum, please let me know.
