Steps
Installing Windows Using a DVD
Fresh Installation
This method is ideal for users who want to install a completely new operating system on their computer (by erasing all data on the hard drive and installing Windows) or for computers without an existing operating system.

Access the BIOS. Turn off the computer where you want to install the operating system and restart it. When the BIOS screen appears, press the Del, Esc, F2, F10, or F9 key (depending on your computer's motherboard) to access the BIOS system. The BIOS access key is usually displayed on the screen.

Locate the boot options menu. The BIOS boot options menu may vary in position, name, or icon, but you will still be able to find it.
- If you can't locate the boot options menu, search online for the BIOS name (usually found in the BIOS menu) for more information.

Set the CD-ROM drive as the primary boot device.
- Although each computer model is different, the boot options menu typically lists removable devices, where you can configure the CD-ROM drive to boot first. You will see a list of devices in boot order. Refer to the manual or search online if you can't find the boot options menu.

Save the changes. Press the designated button on the screen and select the save option in the BIOS menu to save the configuration.

Shut down the computer. You can power it off by selecting the shutdown option in the current operating system or by holding the power button until the computer turns off.
