Restart the computer from the Start menu in Windows 7 or the Start screen in Windows 8. Wait for the computer to shutdown, reboot and enter the boot screen.
Press the Tab key during boot-up. If nothing happens, and you see the Windows logo, restart the computer again. Try pressing the Del key during the reboot. Some eMachines also use the F2 key to enter the BIOS. Therefore, try each key if you fail to access the BIOS settings screen on the first or second attempt. If you still cannot access the BIOS, refer to your manual for the correct key or keys to press following the reboot.
Enter the BIOS, and make any changes to configure your system. Use the arrow keys to select different menus. Pay attention to the instructions on the screen, as you have to press a certain key to trigger an event, such as Enter to confirm a change or Esc to exit the BIOS.
