Hi, there's a couple of ideas that MIGHT work. It sounds as though you have one operating system on a FAT32 partition and another on NTFS. So, either put in the floppy start-up disc from another OS e.g ME and 'fdisk', removing the FAT32 DOS partition and keep the NTFS or go to active patitions and delete the NTFS OR put in your XP disc and when it asks where you want to install.............select the partition you DONT want and press 'D' to delete it. Then using the options format and partition using the NTFS and reinstall. Hopefully you can maybe get somewhere with that. Good luck.........
