Yes that would be the best way. You essentially got the SATA drivers confused with the Chipset drivers. Actually I updated the wiki to add a bit about loading the SATA drivers during the install as I realise a small minority of people have problems with them. You may want to carry out that additional step just in case. In your previous case Windows 7 either downloaded the missing chipset drivers via Windows Update or had one inbuilt. Note as you are using a Retail DVD to reinstall Windows 7 you can make a bootable USB with a Windows 7 with Service Pack 1 .iso  to make a bootable USB/DVD as mentioned here. However using your existing DVD and immediately installing Service Pack after will yield the same result.  
  Hello natakuc4, I am thankful for your wiki list on the OS clean installation. Very informative and wonderful. I see the order of driver installation  A Clean Install of Windows Vista/Windows    1. The chip set then 9. Intel Matrix Storage Manager [if applicable] under SATA drivers.   Now I am in need of replacement of the HDDS in my Dimension 9200 XPS 410 bought in January 2007.   I thought in my case when I install the IMSM that will have the chipset 965 too? I am a bit confused . Should I look fro my chipset separately? to download? I intend to install the Win7 x64 retail OS.   I would appreciate your input..   Regards      
Hi natakuc4 a question with regard to the order of installation?
