To start this Windows install. First check that the first boot device in your system BIOS is set to the CD-ROM Drive.
( To find out how to access the BIOS please refer to your motherboard manual or the manufacturer of your computer. (The system bios can usually be entered on boot, usually by pressing the F1, F2, F8, F10 or DEL key. Make sure you save the settings before exiting))

You will know that your computer will/has booted of CD-ROM when the following screen appears.
The link above walks you through the process of installing windows 98 from scratch. I recently helped my brother install this over the telephone and found the guide extremely helpful. Some of you might find it useful as well.
