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 Laptop. (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))
If you are unsure or don't want to enter the BIOS then just test the computer by putting the CD-ROM in the drive and reboot your computer. This is the recommended way to install windows.
