How to manually reinstall Windows Vista on old DELL computers

In certain cases, you may need to manually reinstall Windows Vista operating system on your Dell computer.

Before you begin

  • Restoring your computer to its original factory settings takes less time than reinstalling Windows Vista. Going back to factory settings could be a better solution for you. Keep in mind that after reinstalling Windows Vista, you will no longer have this option.
  • An optical drive is required to reinstall your operating system using the Windows Vista CD/DVD. If you don’t have an optical drive, you can send in your computer for repair or purchase an optical drive.
  • If your computer has more than one hard drive and a RAID configuration installed, refer to your User’s Guide for instructions on how to configure it for reinstallation.

You will need

  • Dell Operating System Reinstallation CD/DVD
  • Dell Resource CD/DVD (also available on the Dell Drivers and Downloads page)
  • Any software and/or documentation for your Internet service connection
  • Any program installation discs

  • If you did not receive installation media with your Dell computer, access backup and recovery software without installation media.

It’s a good idea to back up important files and data regularly, especially before you reinstall Windows Vista. If you don’t back up your data, you could lose your personal files.
