EDIT: all values here are generic and non specific, you'll need to discover the values on your own machine
firstly we need to know the device name of your vista partition e.g. /dev/sda1
then we assume that your vista partition is ntfs format.
you may need to also install ntfs-3g from the debian repositories
once you know all this, you'll need to create a mount point which is just an empty folder somewhere e.g. /media/vista
then the line you add to your /etc/fstab file should looks something like
Code:
/dev/sda1 /media/vista ntfs-3g realatime 0 0
