Step 3 - What to do with the ISO DVD/USB? How to Change the Boot Order?

Get the Computer to Read the ISO and Install Windows

1.   Once you've got the ISO on a DVD (or USB drive), you'll have to:

             -turn the computer on, put the DVD in the tray,

             -power back down

        (For USB drives, just plug it in before turning the computer on.)

2.   Once the DVD is in the tray, you'll have to tell the computer to boot to the DVD (or USB drive) rather than the hard drive as it usually does. The best way to do this is to catch the computer right after you've powered it on, before it has a chance to load (or attempt to load) the installed operating system.

3.   Press the Power button to turn the computer on and immediately start tapping F9 repeatedly to enter the Boot Order Menu directly.

Could be a different key on a lot of models, but most laptops made within the past 3 or 4 years use the F9 key at power on to enter the Boot Order Menu directly. If your model doesn't bring up the Boot Order menu with F9, the first screen you see after the computer powers on will tell you what F key to press to enter the BIOS. In the BIOS, you're looking for Boot Options and within Boot Options, you'll find Boot Order. If F9 doesn't work, follow the instructions for questions at the bottom of the post.

4.   In the Boot Order Menu, select the CD/DVD/Optical Drive (or USB drive if you're using a USB drive). 

5.   Give the computer some time to load from the DVD (or USB). It should then present you with a Windows Install screen. Most issues here are due to a corrupted ISO. Try just re-downloading the files and recreating the ISO or re-burning the disc. If that doesn't work, follow the instructions for questions at the bottom of this post. Create a new post. Include what error message you're receiving. 

6.    It will ask you for the Product Key. The Product Key is located on a Microsoft label on the bottom of the laptop (sides or back for a desktop). The Microsoft Label will name the version of Windows that Product Key is for. That version must match the version that your ISO is for. (EXAMPLE: A Vista Product Key will not work with a Windows 7 ISO or any other Windows ISO, other than Vista.) How is this legal?

The install will take about 30-45 minutes. Don't interrupt it and be SURE that the power cord stays plugged in throughout the installation.

7.    Another important note: If you had to go all the way into BIOS and change the Boot Order to the DVD drive (or USB), you'll have to go back into BIOS at your convenience and change the Boot Order back to booting from the internal Hard Drive first. If you used the F9 Boot Order Menu, it only changes it temporarily, for that one power on iteration.
