Examples of Editing BIOS Setup Parameters. Part I

If the BIOS interface with the main menu in two columns is used on your computer, there will be the following sequence.

  1. Reboot the computer.
  2. At the initial stages of self-test (POST) press the key to enter BIOS (it is usually Delete or F2). Wait for the main window of BIOS Setup. If you have not press the key on time and the operating system has booted instead of Setup Enter, reboot your computer and try again.
  3. Using the cursors buttons, select necessary partition in the main window (in our case it is Advanced BIOS Features) and press Enter.
  4. Remember or better write down the current values of parameters of chosen partition, in case of wrong action you could reset some settings to their original values.
  5. The parameter defining the first bootable device is usually called “First Boot Device” (1st Boot Device), so select it out of the list. In this case parameter CDROM or CD/DVD must be set up. The value of selected parameter may be changed as follows:
  • consistently press the buttons Page Up/Page Down (or +/- on the numeric keypad) till necessary value of the parameter is set up;
  • press Enter button, select necessary value from the window and press Enter button again. This way is more convenient but it is not compatible with some earlier versions of BIOS.
  1. Quit into the main program menu by pressing Esc button.                                                                                                                                                                                                                               Безымянный
  2. To exit BIOS Setup with saving all changes, select “Save&Exit Setup” and confirm your action in the window that appears by pressing the buttons Y and Enter.


Never log out of BIOS Setup with saving all changes if you have moved some parameters negligently or out of curiosity. In this case it is necessary to log out of BIOS Setup without any changes, then enter it again and edit the desired parameter.

  1. Check the functioning of changes by CD booting.
  2. Reboot your computer again and return the former value of the First Boot Device parameter, then try to start your computer in its normal operation.
