Did you upgrade from Windows 7 or did you install Windows 8 on a separate partition away from Windows 7?

If its on a partition, then boot to your Windows 7 installation:

--------------------------------------

Click Start, right click Computer

Click Manage

Expand Disk Management

Select the Windows 8 partition.

Right click it, click 'Format'

You will receive a Warning dialog, click OK to continue.

The next step is to select your file system option, in this case, go with the default which is NTFS.

The formatting process will now begin.

Once complete, the drive will be displayed as a ‘Logical Drive’ in Disk Management.

Right click the ‘Logical Drive’ in Disk Management, on the contextual menu, click the ‘Delete Volume’ option. Click ‘Yes’ when the warning dialog appears.

The Volume you deleted will now appear as ‘Free space’, you will also notice that the disk icon no longer appears in the list of volumes.

Right click the Free space partition, and click Delete, click Yes on the Disk Management warning that appears.

 

The volume will now appear as Unallocated. (good stuff). Our next step is to merge back that unallocated free space with the system partition. Right click the System volume and click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.

A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.

The wizard provides a simple procedure to merge back the unallocated space with the system drive. Once you have selected the space, click Next, at the end of the wizard, you will see the amount allocated.

---------------------

If you upgraded from Windows 7 then you will reinstall Windows 7 from the original installation disc:

Windows 7 came preinstalled on your computer, you can try reinstalling using the recovery partition if there is one available:

 

New computers that come preinstalled with Windows 7 often have what is called a recovery partition. This is used to reinstall the operating system in the event of a system crash. To access it, you will need to boot into when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 or even DEL or Tab key. Consult the owners manual that came with your PC for instructions about how to reinstall Windows.

 

If your recovery partition is not available or damaged, you should contact the manufacturer of your computer and request a recovery disc set you can use to reinstall Windows 7. They might charge a small shipping and handling fee.

------------------------------------

This is how the recovery partition is accessed for the most popular makes

For Dell, press CTRL + F11 directly after powering up the unit

For HP, press F11 directly after powering up the unit

For Toshiba, press and hold '0' BEFORE and during the power up

For Acer, press and hold ALT + F10 as soon as you see the logo

For Asus, press F9 as soon as you see the Asus logo.

For Advent, restart your computer. Then Press F10 repeatedly until the message "Starting System Recovery" is displayed
