Windows 7 & Vista - Running Checkdisk from a Boot CD/DVD or Windows Desktop

If Windows will not boot in either normal or safe mode, there may be a problem with the file system on your hard drive, or the hard drive itself. Microsoft provides a utility, checkdisk, that can help determine the state of your hard drive.

  2. If you are prompted to Press any key to boot from CD or DVD... do so. If you do not press a key before the message disappears, the computer will not start using the CD or DVD.
  3. After your computer has booted from the disc, select your language and then press Next, as shown below.
