A+: Clean Install from the Distribution DVD

There are two ways to perform a clean install of Windows Vista from the distribution DVD:

    • Install Windows Vista by running the Setup program from within the current version of Windows. (This is the recommended method.) Insert the Windows Vista DVD. Otherwise, go to the DVD drive in Windows Explorer and double-click the setup.exe file to start the installation.

    • Boot the computer from the Windows Vista DVD. This is necessary if no operating system exists on the computer. If you choose this option, follow these steps:

    Step 1. Make sure the DVD drive is configured as the first boot device in the system BIOS.

    Step 2. Insert the Windows Vista DVD into the system’s DVD drive. (If the drive won’t open while in the BIOS, insert the disc immediately after saving the BIOS.)

    Step 3. Save the BIOS and restart the system.

    Step 4. The DVD should boot automatically and start the installation, but if you are prompted to boot from the DVD, press any key.

Microsoft recommends that the DVD-ROM be used for installations of Windows Vista; however, it is possible to order a CD-ROM version, if you can provide proof of purchase. To do so, visit this site: http://www.microsoft.com/windowsvista/1033/ordermedia/default.mspx.
Keep in mind that unattended installations of 7 or Vista from CD-ROM are not possible due to the fact that the Vista files span multiple CDs.
