Create a System Repair Disc in Windows 7
Create System Repair Disc
Type system repair disc into the search box in the Start menu.
The dialog box opens where you select the right drive and click Create disc. A CD will be fine as it only takes up 142MB of space.
Using the Disc
If you are having problems with your machine just pop in the recovery disc and boot from it and enter into Windows Setup [EMS Enabled].
After it boots up you can access recovery tools or restore the computer back to a system image
Now you can choose from different recovery options to help you get your machine back up and running.
You never know when an Operating System disaster might occur, but having a System Recovery Disc to boot from should be part of your backup and recovery toolbox in case it does.
