I suggest speaking (typing) in whole words and sentences---it will make your posts easier to understand.
When you say "mount Windows", do you mean mount the Windows partition? i.e. is Windows already installed in a dual-boot setup? If so, look in /mnt or /media for a mountpoint that has already been setup. Chances are you can mount the partition be simply entering "mount <mountpoint_name>"
In the graphical interface, you can probably find the mountpoint in "My Computer", and simply rt-click and select "mount"
If in doubt, post the results of "ls /mnt" and "ls /media"
