How to System Restore From BIOSby Amy Scott
System Restore can help restore your computer to a previous working state if you find you are having serious problems with it. This can be useful if you install a program that causes issues with the computer or believe settings have been changed. Even if your computer will not start up, you can perform a System Restore from the BIOS with the Windows 7 installation disc in the drive.
Open the CD drive of your computer while your computer is off and place the Windows 7 installation disc that came with your computer in the drive. Close the drive.
Press the power button on your computer to turn it on. Wait for the prompt to press a key to start Recovery Mode. Press any key on the keyboard to start.
Use the drop-down menus to select your preferred language, time and currency settings and keyboard input preference. Click the "Next" button.
Click on the "Repair your Computer" option.
Click on your Windows 7 operating system in the list provided and click "Next."
Click the "System Restore" option to begin the System Restore process.
Click "Next" to start the wizard. Click to select the restore point you would like to restore from the list that is presented to you and click "Next." Click the "Finish" button on the next frame to restart and restore your computer to that point. Click the "Restart" button when prompted to restart your computer to its restored state.
