How to Use a Recovery Disc
If you turn on your computer and the operating system will not load, there are several troubleshooting methods you could. If those fail, you can reinstall the operating system using your recovery disc. The recovery disc includes the Windows operating system and may contain default programs that were added by your computer manufacturer.
Locate the recovery disc that came with your computer. It will be a CD with “Recovery Disc” or similar wording on it.
Insert your recovery disc. Click the Windows "Start" menu and select "Restart." If your computer is off, you will have to boot up your computer, put the CD in and then restart the computer.
With the CD in the computer, the computer will boot from the recovery disc.
Select the option to recover the system without formatting the hard drive. This may say "recover" or it may say "repair." Use this option first, especially if you have personal files on your system that you don't want to lose. The recovery process will begin.
Answer any questions that may appear after the recovery process is complete. Your system will restart, and you may have to set your computer up again with the the date, time, computer description and other information.
Check your system to make sure your personal files are still there. If the files are missing, you will have to reload them if you have a backup. Also check your Internet settings and email configuration.
