It is possible its called Dual boot option.
Create/Obtain an Installation Disc
Yes, we’re all aware most motherboards
these days allow you to boot from a USB flash drive, but setting that
up is a guide in itself. We’re going to assume that you either already
have a Windows 7 DVD, or have an ISO file. If the former is true, feel
free to skip ahead to Step 2.
To create a Windows 7 disc, pop a blank DVD into your burner,
and burn it as an image file with any of the countless apps that can
handle ISOs. Our personal favorite is ImgBurn
, but to name some others: Burn4Free CD and DVD
and Ashampoo Burning Studio Free
Create a New Partition
Editor’s note: Before continuing I’d like to take a moment to
acknowledge the fact that data corruption is a possibility. Even though
this guide is absolutely harmless, random software anomalies can and do occur – do yourself a favor and backup your precious data before proceeding.
Moving on to more pressing matters, we will need to create unallocated
disk space by resizing an existing partition in your current hard drive
and then create a new partition on that free space for Windows 7 to run
on. Most of you who are reading this will probably only have one
existing partition, dedicated to the operating system you’re currently
With that in mind, to help you in the process of creating a new
partition we’ll be looking at two separate approaches. While Windows
Vista has built-in utilities to resize active partitions, XP does not,
and thus we must resort to using a third party application (GParted).
Create a New Partition on Windows VistaIf
you are currently running Windows Vista as your primary operating
system, we can use its built-in tools to modify your hard drive
partitions. You can also use a third-party tool called GParted, which
we are recommending to Windows XP users (see below). You can skip to
the XP section and follow the exact same directions if you prefer the
GParted route for any reason.
On Windows Vista, click Start and enter “diskmgmt.msc” into the
search bar. A window titled “Disk Management” should open displaying
basic information about the drives attached to your PC.
Right click the partition on “Disk 0” and select “Shrink Volume”.
This should present you with drive capacity information as well as
the option to enter an amount you'd like to “shrink” your partition by.
The recommended minimum partition size for Windows 7 is 16GB, so enter
a figure of that size or larger and then hit “Shrink”.
You should now see unallocated space on your hard drive in the
capacity you specified, situated just after your now resized original
Before creating a new partition and assigning a letter to it,
be a perfectionist and reassign your optical drives to the next letter
down from what they are now, so that your new empty partition can have
whatever letter follows your first partition (probably “D”).
Right click the newly unallocated space and select “New Simple Volume...” which ought to open a wizard screen.
On your way through the wizard you'll be asked to define the
capacity for your new volume to be; let it occupy the entire size of
the unallocated space you've created, assign it the letter that you've
just freed, quick format the volume using the NTFS file system and
default allocation unit size (volume label can be anything, just name
it Windows 7).
You should now see a healthy primary partition with the capacity and
label previously defined replace the unallocated space. With that, you
can move on to Step 3
