In order to see the windows partition, you'll need to have it mounted. If Linux didn't let you add it during setup, it's easy enough to do. Make a directory that you want to mount it to, let us say /mnt/windows; you would type mkdir /mnt/windows then almost positively your win partition is hda1 but to make sure type fdisk -l /dev/hda and look for the fat/windows partition and note the hd(?). You can mount it instantly by doing this;
mount /dev/hda1 /mnt/windows
Or to mount on startup everytime, you have to edit your /etc/fstab file and add a line that looks like this;
/dev/hda1 /mnt/windows vfat defaults 1 0
Then it's set to go. If you still can't see files to copy over, you may have an unreadable or too badly damaged partition to read per se.
