that will let us do just that.
Right-click on your Vista partition
(in this case, C drive) and select “Shrink
Volume” as shown in Figure 2. This
will pop up the form shown in Figure 3.
Vista is now supposed to determine the
maximum it can shrink the drive and
place that value in the editable field
shown. You can look at the other fields
to see what will be left for Vista. For XP,
I recommend at least 20 GB, but it all
depends on how large your drive is and
what you plan on doing with XP. In my
case, I am going to take the default.
When satisfied, hit the Shrink button.
Once Vista has completed the
change, you will have a new
unallocated partition located at the
end of your Vista partition as shown in
Figure 4. Vista may not allow you to get
the space you want. In this case, you
have a couple of options. First, you can
remove your recovery partition. In my
case, it freed up an additional 12 GB.
Vista has a page file that can keep you
from resizing if it’s located near the end
of the partition. If this happens, you
have a couple choices. First, you can
remove the pagefile.sys file then have
Vista build a new one. The easier way is
to back up the drive then restore it.
Most backup software will not back up
the pagefile.sys file. Vista just restores
the file when it sees it’s missing.
My recommendation is to remove
the recovery partition. Before you do
so, make sure you have a backup or a
set of backup disks. Removing this
partition makes for a cleaner install and
yields more space for your XP partition.
Step 3: Prep New Partition
Right-click on the new partition
and select the “New Simple Volume”
option as shown in Figure 5. Select the
default options until you get to the
Format Partition form shown in Figure
6. Change the volume label to XP and
check the “Quick Format” option. Hit
the Next button
and finish the
operation. After a
couple of minutes,
Vista will transform
the partition into a
When this is all said and done, you ■ FIGURE
should have two
partitions on your hard
drive configured as
shown in Figure 7.
Exit the Computer
Management form and prepare to
boot from the Spotmau power suite
software. Before you reboot, you may
want to change the drive label for the
Vista partition. If you change it to
“Vista,” it will make it easier to identify
the partitions later.
Step 4: Hide Partitions
At this point, you need to hide the
Vista and Recovery partitions from the
XP installer. If you don’t, they will get
all mucked up. Insert your partition
utility boot software and restart you
computer. (Another product you can
use for this task is the Acronis Disk
Director Suite.) When PowerSuite 2008
starts, select the advanced mode. You
will be prompted for various boot
choices such as resolution and color
depth. Choose whatever best suits your
computer. I chose the VBE option
when prompted for the display driver.
When the application screen
shown in Figure 8 is presented,
select the Partition Genius
application. Right-click on the
Vista partition and select “Hide
Partition” from the Advanced
menu as shown in Figure 9. It will
give you various prompts; just click
the Apply button as each one
pops up. By hiding this first
partition, we are telling the XP
installer to ignore this drive when
we do the install. Failure to do this
will render the Vista partition
unbootable and will totally muck
up the XP installation, as well.
Step 5: Install XP
Exit the current form by hitting the
small X in the top righthand corner.
When presented with the application
screen, click the Exit icon. You will be

prompted to hit Enter when it’s ready
to reboot. At this point, you need to
remove the Spotmau disk and insert
the XP Install disk.
Reboot the machine to start the
installation process. It will take a few
