Hello Dell-Royan S,
I tried your link but after I got into "Repair Your Computer" and logged in as Administrator, I did not get an option for "Dell Factory Image Restore.
The only options I have are;
System Image Recovery
Windows Memory Diagnostic
System Restore will not work and System Image Recovery states that Windows cannot find a system image on this computer.
Ok, got it figured out.
Now I have the option "Dell Factory Image Restore" after going into F8 Repair your computer.
The problem is that nowhere does it tell you that your system needs to have Dell's Backup and Recovery Manager software installed and have created a system backup disc prior or else you won't get this option.
Our laptop did not have Dell Backup and Recovery Manager factory installed. I had to download and install it from Dell's site.
