To create a system repair disk for Windows 7, go to the Start Menu, select All Programs, then Maintenance and finally Create a System Repair Disc. In the dialog box, select an optical disc drive. Insert an unused disc in the selected drive, and click Create Disc.
Another way to open the dialog box for creating a system repair disc in Windows 7 is by typing the "recdisc" command in the Run dialog box or going to the Backup and Restore applet in the Control Panel. Creating a system repair disc requires a disc-burning optical drive and a recordable CD, DVD or Blu-ray disc. The computer may ask for the credentials of an administrator account or a Windows 7 installation disc before it can proceed. The time required to create a system repair disc is approximately five minutes.
To use the disc, restart the computer, and boot from the disc. Configure the BIOS settings if the computer fails to detect and start from the disc.
A system repair disc provides access to built-in recovery tools and helps fix problems that prevent Windows from loading normally. These tools include Startup Repair, System Restore, System Image Recovery and Windows Memory Diagnostic. Keep the disc in a secure location when not in use, and label it properly.
