How to Do a Clean Installation of Windows 7 from the Windows Desktop
This shows how to do a clean installation of Windows 7 from the Windows 7 desktop, using only an ISO - Disk Image File; though you will have to supply a valid, purchased Windows 7 activation key for the Windows 7 version you install.

This method is very helpful if you don't have a way to boot the Windows 7 installation media, whether the CD/DVD drive is not functioning or not present, as in a Netbook; or the PC is not capable of booting independently from a USB stick.
warning   Warning

Be advised: You must make back-ups of any personal data you need to save to external media before you start this process as it will over-write all data on the Windows 7 partition and it will not be recoverable at all after this installation is finished, this is not an upgrade.

You will have to reinstall all the programs/apps that you use as they integrate themselves into the Windows registry and are not moveable from one Windows installation to another so be sure to save the program installers and the product activation keys where applicable.

As there is no upgrade path to go from 32-bit to 64-bit, or vise-versa, this method will not work for that, that has to be a true, complete clean installation from scratch.
This works exactly the same to clean install Windows 7 from the Vista desktop.
If you need information on how best to extract the Windows 7 installation files from an ISO to the Windows 7 desktop, have a look at the tutorial at this link.
ISO - Disk Image File : Extract to the Desktop
If you want to copy the Windows 7 installation files to the Windows 7 desktop from a Windows 7 installation DVD, have a look at the Copy To method of this tutorial.
Context Menu - Add Copy To Folder and Move To Folder
Let's get started!

1) Right click Setup and select Run as Administrator and enter your user credentials for the UAC prompt, then click OK to start the process.

3) You'll get Setup is Starting; then this Get Updates dialog box, just select to not get updates during the installation process, it just seems to go smoother this way, Windows will auto-update later, after the installation has completed.

Hello RJ,

No worries. The items highlighted in the screenshot is what is supposed to be selected.

However, you could also just let it sit and automatically choose for you when the timer runs out at step 7 and 8 to continue with the installation.
