If your computer's system is severely damaged and you can't access the System Recovery Options menu on your computer, you can access it using the Windows 7 installation disc or a USB flash drive, or using a system repair disc if you created one earlier.
Insert the Windows 7 installation disc or USB flash drive, or a system repair disc, and then shut down your computer. On the Install Windows page, or on the System Recovery Options page, choose your language and other preferences, and then click Next. If neither the Install Windows page nor the System Recovery Options page appear, and you're not asked to press any key, you might need to change some system settings.

If you've used Windows Complete PC to create a system image backup as part of your backup plan, you can use the system image to restore your computer.
A system image is a copy of the partition on your hard disk that contains Windows. It also contains everything on that partition on the date you created the image, including Windows, your programs, and user data—such as documents, pictures, and music. You need to have created a system image beforehand to use this option. When you restore your computer from a system image, the contents of your hard disk are replaced with the contents of the system image.
This means that any changes you've made, programs you've installed, or files you've saved after the system image was created will likely be lost unless you have a recent backup of your data. Restore from a system image using the Windows 7 installation disc or a USB flash drive, or a system repair disc.
