NTFS, by being a proprietary FS, is poorly supported in free software (such as Linux (the kernel)).
Currently, there's read support, and experimental, limited write support (read: there's read support, period).
Linux (the kernel) does support FAT, though, so you may want to convert some or all NTFS space to FAT, depending on your needs.
I *order* you to read ESR's `Smart Questions' (GIYF)--your explanations are way too fuzzy. Also, read `Bug Reports' (linked to by ESR's SQ).
I imagine the following should work:
# mount /dev/hdXY /mnt
Otherwise, read man mount and man fstab (that's /etc/fstab).
Post your lilo.conf; rtm if you haven't already.
