Your hardware system BIOS controls many basic functions of your computer. This chapter discusses the need for being able to boot from a DVD/CD-ROM. You can find out how your system BIOS handles DVD/CD-ROM booting by displaying the BIOS Setup or Configuration screen on your computer. To display your current booting options by looking at your BIOS:
1. Display your computer’s BIOS Setup or Configuration screen. How you do this varies with the machine, but common techniques are to press F1 or F2 during the system bootup process. Other keystrokes or combinations may be used, such as Del, Ctrl+Alt+Esc simultaneously, or F10. Another way is to hold down a key on the keyboard while booting. The BIOS often sees the error and gives you the option to go into Setup. If none of these works, study your computer’s documentation, or carefully read all screens during system boot.
2. Look for settings for boot order or boot sequence. This usually involves using the cursor keys to position the cursor over a field, then pressing the spacebar or Page Up/Page Down to step through the settings.
3. Step through the choices available on your machine.
4. If available (and with your instructor’s permission), choose a DVD/CD-ROM boot, and save and exit the Setup or Configuration screen.
5. Insert your operating system DVD/CD-ROM disk and reboot the computer. Did the DVD/CD-ROM boot your computer? What error messages did you see, if any? Can you reconfigure your system to boot from your hard disk drive?
