The mount point can be anywhere you want it to be.
Sometimes, mount points will get set up automatically--typically in /mnt or /media
To see what is already mounted, enter "mount"
To see what is already SET UP to be mounted, enter "more /etc/fstab"
From scratch (assuming that Windows is on sda1):
Commands must be run as root
Code:
mkdir /mnt/windows
mount /dev/sda1 /mnt/windows
cd /mnt/windows
ls
You should now be looking at the contents of the windows partition
