   Step 2: Insert your Windows XP installation disc.

   Formatting the C: drive requires uninstalling your current installation of Windows.
   
   To do this, you'll need your Windows XP installation disc.
   
   You can also use any other version of Windows' installation disc.
   
   If you can't find your disc, you can download an ISO of the Windows installation disc and burn it to a blank DVD.
   
   This is legal if you own Windows. , Once you've inserted the disc, you will need to set your computer to boot from it instead of the hard drive.
   
   You can change the boot order from the BIOS, which can be accessed by pressing the setup key as your computer boots.
   
   The setup key is usually F2, F10, or Delete.
   
   You can change the boot order from the Boot or Boot Order menu.
   
   Make sure that the optical drive is set as the first boot device.
   
   See this guide for more details on opening your BIOS and changing the boot order. , Once the boot order is set, restart the computer.
   
   You will see the message Press any key to boot from CD.
   
   Press a key on your keyboard to start the setup program.
   
   The setup program may take a few minutes to load.
   
   Once the setup program finishes loading, press Enter to get started. , You will be shown the Windows XP license agreement.
   
   Since you're only uninstalling Windows XP, you don't need to worry about reading it.
   
   Press F8 to move on. , You will be shown a list of all the partitions on your computer.
   
   Highlight your Windows partition, which is also the C: drive.
   
   Press D to delete the selected partition.
   
   This will delete all of the data on this partition, so make sure you have everything you want saved first. , Once the Windows partition has been deleted, you can format the unpartitioned space.
   
   This will happen automatically if you install a new operating system, or you can manually format by selecting the unpartitioned space and pressing C.
   
   You will need to specify the size of the partition, the drive letter you want to assign, and the file system format.
   
   In nearly all cases, you'll want to choose NTFS as the file-system.
   
   Avoid choosing a quick format, as this will not fix any errors you might be experiencing with the drive. , Once you've formatted your C: drive, you will need to install a new operating system in order to use your computer.
