You need to create a new partition but, as your C: drive is taking up all of
your hard drive space this will need to be shrunk. In other words you need
to shrink your C: drive to give you enough free space to create a second
partition.
While Vista 'can' shrink a partition it isn't very successful at doing it,
for this reason it is better to shrink the partition using third party
software such a Acronis Disk Director or something similar.
Once you have shrunk your C: drive, then create a new partition in the
available free space; I usually allocate around 60GB for Win 7. Again you
can create the new partition using Acronis Disk Director (or use Vista own
Disk Management tools, if you wish).
Once the new partition has been created ensure it has a drive letter and it
is best to 'name' the partition so that you don't get confused when
installing Win 7. For simplicity I would name the partition 'Win 7.'
All that is left to do is to slip the Win 7 DVD into your CD/DVD (making
sure that the CD/DVD is the first boot option in the BIOS - if your machine
is 3 years or less in age the CD/DVD should be the first boot option by
default anyway.)
Once the DVD is in the drive reboot your machine. You will see a screen
which says 'press any key to boot from CD/DVD; just press the space bar or
Enter key for the installation to start. Installing Win 7 isn't any
different from installing any other version of Windows, only slightly
faster. Just make sure you install Win 7 to your 'Win 7' named partition (or
whatever name you have called the partition.)
After Win 7 has been installed and you reboot your computer a menu will
appear asking you which version of Windows you wish to boot to. Just select
either Vista or Windows 7 and the relevant window version will load.
