To boot a computer from a CD, the CD must contain a bootable program, such as an operating system. In addition, the computer's boot order must have the CD drive listed first. The BIOS varies in computers, so look to the manual for more information on changing the boot order.
- Insert the CD
Turn on the computer, and insert the CD in the disc tray. Next, reboot the computer, and watch the screen during the process. Look for a message at the top of the screen that prompts you to press any key to boot from the CD. If you miss the message, the Windows logo appears; just reboot the computer again, and watch for the prompt.
- Press any key
When you see the message, press any key on your keyboard. If you have done this step correctly, the disc drive spins and makes noise. Give it a few seconds or minutes to gather the information on the CD.
- Run the program
Run the program once the computer boots into the CD. If the CD contains an operating system, follow the instructions in order to ensure everything goes well. If you make a mistake and need to start again, reboot the computer, and start at step two.
