Well, first of all you need to check on which partition is your Win.
For e.g. : hdaX, where X is for the parition on which you have Win.
You need to make also a new directory: mkdir /mnt/win
After the u need to edit /etc/fstab
U need to add last line similar to:
/dev/hdaX /mnt/win vfat default 0 0
And in the end you just need to mount it:
either by mount -a
or mount /dev/hdaX /mnt/win
And after that, you will be able to see you windows partition in :/mnt/win
Hope that i'm right
Cheers
