Win7 comes with recovery function to create a system restore disk graphic steps

The Windows 7 system provides users with the ability to create a restore system disk, and the same functionality can be found on the Windows 7 installation disk. If there is no installation disk (such as the OEM version of the laptop), or if the installation disk is lost or damaged, you can restore the CD from the system in this way.
Create System Restore CD in 3 steps:
1. Click on Windows, select “Start”>Control Panel>System & Security>Backup & Restore

Select &ldquo ; Create a system recovery disk & rdquo;.
2. If there are multiple optional hard disks in the system, select CD or DVD from the drop-down menu to burn. Insert the CD or DVD into the drive and click “Create Disk”.

3. After completing the above steps, you will see the system creation process bar. It takes only a few minutes for the Windows 7 system to create a recovery disc. Finish clicking <;OK”

Prepare the Windows 7 system for a rainy day, in case you need it later
