The steps posted for running Dell Factory Recovery are for Win7.
What type of file do you have for Win7 installer? Is it an ISO? Rightclick on it and look at Properties to see the file type.
The MS tool you referred to is to burn an ISO to DVD or write it to flash stick.
If you do not have an ISO file, then go back to my earlier post here which will show you how to obtain one for the Student deal, and also gives the steps to a perfect install.
