Yes - All versions of Windows 7 are on the install DVD. The file that determines which version is offered is the ei.cfg file in sources but the fact is that most folks and especially OEM system owners do not have a genuine bootable Windows 7 installation CD/DVD and another fact is that you will not be downloading one from Microsoft with an OEM Product Key.
The COA sticker and 25 character Product Key that came with the Dell tell you what Edition (Home, Pro, etc.) of Windows is tied to that piece of hardware.
If you are not sure visit the Dell WWW site and enter the Service Tag number to see what came from the factory with the unit.
You will not be able to download any Windows 7 installation ISO from the Microsoft site with an OEM (Dell, HP, etc.) product key but you can sure give it a try and find out yourself that it will not work.
If you don't have or can't find any installation media, click my profile and message me and I will help you get any installation ISO you need - everybody should have some installation media handy and you are unlikely to get it from Dell but you can sure try. With me, there is no trying - only doing.
After obtaining the matching Windows 7 installation media and performing a clean install, visit the Dell Support site (with the Service Tag) download/install drivers (chipset, video, audio, network), etc.
After you have installed the Dell drivers allowing you to get on the Internet the unit should not have any problem activating right away.
If there is a problem activating do this:
Click the Start button/orb and in the box enter:
Choose your nearest country (United States in the example), call the toll-free number to speak to a human being:
Don't press any keys on your phone, don't respond to any voice prompts, just wait, wait, wait and you will be connected to a human being.
Explain your situation and they should help you.
If they don't help or can't help just hang up and call back again and the chances are good that you will talk to a different person and eventually you should find some nice person that will help you.
