If for any reason this solution does not work, you can use the "System Restore" option by choosing a restore point created when your computer was still working perfectly. You will be explained, step by step, how to perform both procedures. Read on to find out how.

Method 2 of 2: Use the Windows 7 Installation or Recovery Disc

If your computer turns on but cannot start Windows, you can solve the problem using a Windows 7 installation disc. If you have created a recovery disc, you can use it instead of the installation disc.
If you don't have a Windows 7 installation or recovery DVD, but you have the option of using a computer with a burner, you can use it to create a new installation disc.

If you are using a Windows installation disc, the "Windows Setup" dialog will be displayed; if you are using a recovery disc instead, the "System Recovery Options" dialog box will appear.
