And what file system is on your windows partition? If it's NTFS, you'll need to install NTFS support. (Fedora does not include NTFS support because of "legal issues.") Note that partition type 72 NTFS systems are not generally supported.
Use sudo fdisk -l /dev/hd*
to see what drives and partitions you have.
Then modify your /etc/fstab
to contain lines for your file system. Here's some sample lines:
/dev/hdc1 /mnt/WinXP/g ntfs ro,gid=windows 0 0
/dev/hdg1 /var/share/z vfat gid=windows 0 0
Then the file system(s) should be mounted for you during boot. You can mount from a command prompt by, for example, sudo mount /mnt/WinXP/g
Note that the NTFS is mounted RO. That's because M$ has made it difficult to modify NTFS files without using M$ tools, while reading works fairly well.
