it doesn't mount the windows partitions for you, so you have to mount them manually. first locate a suitable place to mount under /mnt (maybe there is /mnt/win if not you can make a /mnt/win with mkdir command). then use "mount windows-partition mount-location". your windows partition should be /dev/hdXY where X is the letter of your drive (a for master on primary ide channel, b for slave on primary ide channel, c for master on secondary ide channel, d for slave on secondary ide channel) and Y is the partition number. you can see the partitions on your drive with the cfdisk command (be carefully with it though) for example if you enter
cfdisk /dev/hda
you'll see the partitions on your master drive, note the number of the windows partition, then use mount command to mount it
mount /dev/hda3 /mnt/win
just be careful when you quit cfdisk with the quit command, and not the write command, or you may change the partition table.
