How to boot your computer from a CD

If you need to boot your PC from a CD

Normally, a computer is programmed to look up boot files from the hard disk it conceals; however, for one or more reasons, a computer may be unable to boot from the hard disk; thus, requiring an external bootable disk or device. Sometimes, you may just want to boot the PC from a disk as a means of troubleshooting certain issues you’re experiencing with the system. But how do you boot a PC from a disk or device?

First Step:

Firstly, you need to change the boot order. The settings for this are available in the Windows BIOS menu. Basically, your hard disk is the default boot drive; so, you will need to change it and put your PC’s CD, DVD, or BD drive as the first option.

To access BIOS, restart the computer and press the manufacturer’s key repeatedly once the brand logo comes on. Use arrow keys to enter BIOS settings and change the boot order.

Third Step:

During the booting process, you will see a message that reads, “press any key to boot from CD…” As the message reads, press any key on your keyboard immediately it appears. If you do not press “any key” as requested, your system will move on to check for boot files in the next disk/device in your BIOS list. However, some bootable disks won’t prompt the “press any key” message – they’ll just boot straight up.
