hi lapin,
well, from your first screenshot i would say that the ntfs partition is not mounted...
that's why you can't see it :-)
you should find out how to mount ntfs partitions with the linux distribution and destkop environment you're using...
once you will have correctly setup the system, you will probably find the partition under /mnt or under /media
if you need further help, the best thing is if you can find somebody who can help you with the issue in your neighborhood... otherwise ask in here or on irc...
ciao
