If the operating system on your Dell Latitude E6400 laptop computer becomes corrupted or unusable, you may find it necessary to restore the computer back to factory settings. For many computers, this recovery process can be complex and involves finding the system restore disc and downloading the correct drivers to run your system components. Fortunately, Dell includes a partition on the E6400 hard drive that contains the system drivers and restore tools that makes the process quick and easy.
Turn on the computer and tap the "F8" key several times to load the "Vista Advanced Boot Options" menu.

Ensure that you have backed up your system data onto another computer or removable media device before proceeding. The recovery process will take approximately five minutes.
Click "Finish" to restart the computer. Allow the operating system to boot up completely, which completes the recovery process for your Dell Latitude E6400 laptop computer.
