    Hi Emilia,
    You cannot format the hard drive on which Windows is
    running, in your case it is C drive.
    You can't format the C drive like you can format another drive in Windows because you're within Windows when you perform the format.

    The solution is to format C drive from outside of Windows, meaning
    you need a way to format a drive from somewhere other than your Windows
    installation.
    The easiest way to do this is to boot from an operating system (with formatting abilities) via a CD/DVD drive, flash drive, or floppy drive.

    Boot to the Windows 7 Setup DVD.

    1. Watch for the Press any key to boot from CD or DVD... message after your computer turns on and be sure to do that.
    2. If you don't see this message but instead see the Windows is loading files... message, that's fine too.
    3. Wait for the Windows is loading files... and the Starting Windows screens. When they end, you should see the big Windows 7 logo with several drop-down boxes.
    4. Change any Language or Keyboard options if you need to and then click Next.
    5. Click the big Install now button the next screen and then wait through the Setup is starting... screen
    6. You should now be on the Where do you want to install Windows? window. This is where you'll be able to format C.Click the Drive options (advanced) link under the list of hard drives. As you can see, several other options are now available, including Format.
    7. Choose the partition from the list that represents your C drive and then click the Format link.
    8. After clicking Format, you're warned that what you're formatting "...might
      contain recovery files, system files, or important software from your
      computer manufacturer. If you format this partition, any data stored on
      it will be lost."
      Take this seriously! it's very important that you're sure this
      is the C drive and that you're sure that you really do want to format
      it.Click Ok.
    9. Your cursor will turn busy while Windows Setup is formatting the drive.When the cursor turns back into an arrow, the format is complete. You are not otherwise notified that the format is over. 
    10. You can now remove the Windows Setup DVD and turn off your computer.
I hope this helps.

Regards,
Lokesh

Hi Emilia!

Drive C is the partition where your Operating System usually is installed. In order to format it, you need to boot the Windows DVD/USB installer and have it formatted.

In any case, if your operating system isn't installed on Drive C, you can format it using Disk Manager.

Warning
  • Formatting a volume will destroy any data on the partition. Be sure to back up any data you want to save before you begin.
Instructions:
  1. Open Computer Management by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, clicking Administrative Tools, and then double-clicking Computer Management. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  2. In the left pane, under Storage, click Disk Management.
  3. Right-click the volume that you want to format, and then click Format.
  4. To format the volume with the default settings, in the Format dialog box, click OK, and then click OK again.

Notes

  • You cannot format a disk or partition that is currently in use, including the partition that contains Windows.
  • The Perform a quick format option will create a new file table, but will not fully overwrite or erase the volume. Aquick format is much faster than a normal format, which fully erases any existing data on the volume.

Hope this helps.
