Step 1 - Insert the Windows 7 installation DVD into your DVD drive and restart the computer. When you see the prompt to ‘Press any key” to boot from the DVD, do so. Windows 7 will start to boot up and you will see the following progress bar “Windows Is Loading Files” followed by the “Starting Windows” logo.
Step 2 - The next screen allows you to setup your language, time and currency format, keyboard or input method. Choose your required settings and click next to continue.
Step 3 - The next screen allows you to install or repair Windows 7. Since we are doing a clean install, click on "install now". The ‘Setup’ process will then start.
Step 4 - Read the license terms and click ‘I accept the license terms’. Then click ‘Next’ to continue.
Step 5: What type of Installation do you want: There are two options to choose from, Upgrade or Custom (Advanced). Since you are doing a clean install, select the second option ‘Custom (Advanced)’.
Step 6: Choose where you would like to install Windows 7. Since the drive already has been partitioned, formatted and assigned a volume name (Windows 7 Pro), all you need to do is select the third / Windows 7 Pro partition (since that’s what I’m installing) and click ‘Next’.
Step 7 - Windows 7 starts the installation process and begins by copying and expanding all the necessary files to your hard drive or SSD.
Step 8 - The installation will go through various setup stages and then will reboot your system. Warning: Each time your computer reboots it will prompt you to boot from the DVD. Take no action on your part, please do not touch that keyboard, even though you are prompted to “press any key to boot from CD or DVD” just let the computer boot on its own and the installation will automatically continue.
Step 9: The next set of tasks are completely automated and no user intervention is required. You will see a starting Windows logo.
Note: If you failed to Disable Windows 8’s ‘Fast Start’ option, ‘chkdsk’ may run immediately after a reboot, check each partition on your drive and then reboot again to continue the installation.
At this point “Setup is updating registry settings” message quickly followed by a “Setup starting services” message, finally the “Completing installation” message is displayed (your display may flicker). Your computer will then reboot at this point in the installation process.
Setup will now prepare your computer for first use and check your video performance.
10) You will now be prompted to enter a user name and a computer name. Your username will be will become the prefix for the computer name. Click the ‘Next’ button to continue.
11) Set a password for your account: Choose your password and password hint just in case you forget the password and need to jog your memory.
12) This step is where you perform a “Keyless Install”. You could at this point enter the product key that came with the version of Windows 7 you are installing and then click ‘Next’. But wait, if you choose to activate Windows now and something should go wrong anywhere in the process of installing Windows, installing the device drivers or installing the latest Windows Updates and as a result forcing you to start fresh by reinstalling Windows from scratch, the next time you try to activate it will most likely fail and phone activation will be required; not a good idea, especially if there is a better way.
If you do not enter the product key and remove the checkmark from the “Automatically activate Windows when I'm online” box, you can still proceed with the installation process without entering your product key. After the installation has completed, Windows 7 will run in a trial mode for 30 days, this should be more than enough time to install the device drivers, all the Windows Updates, configure and test your dual boot computer before you need to activate Windows.
13) Help protect your computer and improve Windows automatically: Choose ‘Ask me later’, there is no need to be flooded with Windows Updates after the installation has completed.
14) Set the ‘Time zone’, Date and Time for your location. Note: Because you have performed a “Keyless Install” it is very important that you set the Time zone, Date and Time correctly. Then click ‘Next’.
Note: Changing these settings after the install has completed could result in instantly using up your 30 day grace period.
15) Select your computer's current location: Home users should choose ‘Home network’ option, otherwise pick one of the appropriate remaining two options. Windows will now connect to your network and apply the settings.
16) Select what you want to share if a network is detected and enter a password or simply click ‘Skip’.
17) Windows will finalized your settings, prepare your desktop and finally display the Windows 7 style desktop with a “Real” start button in the lower left corner of the ‘Taskbar.
18) The bland grayish color of the toolbar (Non Aero) is a dead giveaway that the graphics card driver has not been installed. Other device drivers will also need to be installed.
19) Remove the Windows 7 installation DVD and reboot to Windows 8 and create another backup before installing any Windows 7 device drivers. You will note the boot menu now takes on the look of a typical Windows 7 dual boot display with Windows 7 at the top of the list and it is also the ‘Default’ OS that will load if no choice is made before the 30 second timeout.
Use the ‘Down’ arrow on the keyboard to select Windows 8 and press the ‘Enter’ key.
20) Reboot to Windows 7 and install your device drivers.
